Helping Hands Community

UX Researcher · Contractor

Helping Hands Community (HHC) is a nonprofit product org (founders from companies like Uber/Google) that built technology so food banks could offer home delivery at scale. The platform connected partner organizations with local end users who carried out deliveries, and used Lyft and Uber APIs for rideshare logistics. My research sat at that intersection: what partners needed to integrate and run the program, and what end users needed in the app to complete deliveries and come back.

Driving Engagement at Flyhomes

Flyhomes · Former employer · 2022

62% of qualified leads abandoned the platform before completing their first search or tour, and the home search feature, Flyhomes' key experience, was only engaged with by 11% of traffic. Usability testing exposed why: almost nobody realized they could search for homes on the site. A second phase tested the rebrand and a redesigned homepage centered on search to better match buyers' mental models.

FinTech Rewards, A Measurable Usability Jump

FinTech · Anonymized

A user opens the rewards screen, taps "redeem," and bounces. That single abandoned flow hid a usability problem worth millions. We benchmarked it, redesigned against the data, and proved the lift with the same numbers leadership trusted.

  • 58 → 81System Usability Scale
  • +53%task completion
  • −47%redemption drop-off
Read the full case study

The business question

A user could open the rewards screen, tap redeem, and leave three steps before completion. That moment made the problem concrete for the team: a high-value flow was losing qualified users before they could understand what had gone wrong.

How I framed the work

I paired a baseline usability benchmark, including System Usability Scale scoring and task analytics, with a heuristic teardown. The baseline gave the team a shared way to describe the problem before discussing solutions.

What we tested

Three rounds of moderated testing examined redesigned redemption flows. Each iteration focused on the moments that made the task harder to complete, then returned to the same baseline measures so the team could compare progress rather than rely on preference alone.

What changed

System Usability Scale scores rose from 58 to 81, task completion increased 53%, and redemption drop-off fell 47%. Measuring the before and after states with the same yardstick gave leadership a credible basis for moving the redesign forward.

Evidence boundary

Client identity, interface details, population definition, and underlying task analytics remain confidential. The approved figures describe the measured redemption flow only. They do not represent a portfolio-wide or post-launch business result.

Journey research and service design

Why Volunteers Deliver Once and Disappear

Helping Hands Community · Nonprofit contract · Jul–Dec 2021

During COVID, Helping Hands Community, a tech nonprofit founded by ex-Google and Lyft leaders, mobilized volunteers to home-deliver food boxes to at-risk neighbors. Deliveries were happening, but volunteers were quietly churning after a single shift. As contract UX researcher (and part-time designer), I stood up the org's first formal research practice, prioritized the work by business and user impact, and treated retention as a journey problem. Interviews, mobile-first usability tests, service blueprints, and synthesis produced six friction themes, POV statements, a future-state volunteer flow, and 18 concrete recommendations the team could ship against.

Three-act case study

Making a digital front door easier to enter

Regional health system · Client anonymized

Patients could lose trust before they reached scheduling. Eight moderated sessions showed that the core issue was not page polish. It was finding the right path with confidence.

  • 8screened participants
  • 60 minscenario-based sessions
  • 2page templates
  • Landing → schedulingjourney covered
Read the full case study
  • RoleLead UX Researcher
  • GoalIdentify findability, trust, and scheduling friction across the patient journey.
  • MethodEight 60-minute, scenario-based walk-the-store sessions, plus open card sorting.
  • ConstraintClient, patient data, interface screens, and downstream conversion data remain private.
01 / Setup
The patient journey started with uncertainty.

The team needed to improve a journey from the landing page to appointment scheduling while validating Orthopedics and Cancer Care templates. The key question was simple: could people find the right service and feel ready to act?

The turning point

Participants did not experience trust as a branding problem. Buried symptom checkers, unclear layouts, and weak calls to action made the next step feel uncertain.

02 / Act II: Investigation
Follow the patient journey before judging the page.

Participants completed realistic scenarios across two page templates. The sessions focused on finding information, interpreting service options, and deciding what to do next, not on visual preference alone.

01
Scenario-based navigation

Sessions recreated the moments when people need to understand symptoms, services, and the next action.

02
Walk-the-store observation

Following the full path made handoffs and dead ends visible instead of treating each page in isolation.

03
Open card sorting

Card sorting tested how patients expected services and support content to be grouped.

Research decision
Improve the path people can understand, not only the pages they can see.

The study put information architecture and progressive disclosure ahead of visual refinement.

03 / Action
Turn uncertainty into a clearer next step.
Recommendations
  • Align the information architecture with patient mental models.
  • Surface symptom support sooner in the journey.
  • Use progressive disclosure so complex choices do not arrive all at once.
Research value
  • Created a strategic baseline for navigation and template decisions.
  • Connected service discovery, trust, and scheduling in one journey view.
04 / Evidence boundary
What this case does and does not claim.
This case covers
  • End-to-end patient journey research from landing to scheduling.
  • Findability, trust, and information architecture recommendations.
This case does not claim
  • No patient outcome, appointment-conversion, or later redesign result.
  • No client identity, private screen, or patient information.
Three-act case study

When invisible security feels like no proof

Smart-home security team · Client anonymized · Applause era

A camera-free security experience could sense motion, but Wi-Fi latency sometimes left people without reliable proof of what the signal meant. Two rounds of diary research turned that trust gap into a focused set of diagnostic, visualization, and feedback recommendations.

Research evidence at a glance
Decision at stake
How might a camera-free security experience make sensed activity understandable and credible?
My role
Co-lead UX Researcher.
Why this approach
A seven-day comparative diary study could capture trust during repeated use, while a single session could not.
Strongest evidence
Across two research rounds, eight participants encountered a “silent entry” moment in which Wi-Fi latency made the meaning of a sensed event unclear.
What the evidence enabled
Recommendations for pre-installation diagnostics, floor-plan visualization of motion data, and active audio feedback. Implementation and outcome are not claimed.
Public evidence boundary
The client, product names, competitors, technical screens, launch status, and downstream performance remain private.
  • 8participants
  • 7 dayscomparative diary study
  • 2research rounds
  • 3recommendation areas
Read the full case study
  • RoleCo-lead UX Researcher
  • GoalUnderstand whether a camera-free security experience could earn user trust.
  • MethodTwo-round comparative diary study with daily surveys and final video testimonials.
  • ConstraintProduct names, competing products, technical screens, and launch details remain private.
01 / Setup
Security without a camera asks for a different kind of confidence.

The team needed to test setup, feature discovery, and the emotional effect of protection people could not visually verify.

The turning point

Wi-Fi latency created a silent-entry failure. The system had a signal, but users had no reliable proof of what it meant.

02 / Research
Let the first week change the second.
01
Two rounds, not one static study

Daily diary evidence shaped the focus of the second round while the experience was still fresh.

02
Trust as a mental model

The research tested whether people could understand and believe an invisible form of coverage.

03
Engineering in the room

The finding linked user doubt to data quality, not just to interface wording or education.

Research decision
When the signal is late, the product has to explain what users can trust.

The design question shifted from feature discovery to visible evidence and better diagnostics.

03 / Action
Make trust observable before asking users to rely on it.
Recommendations
  • Build a pre-installation diagnostic to filter poor ISP data.
  • Visualize motion data on a floor plan.
  • Add active audio feedback to make system response clearer.
Research value
  • Turned a vague trust concern into a specific failure loop.
  • Gave product and engineering a shared direction for resolving it.
04 / Evidence boundary
What this case does and does not claim.
This case covers
  • Iterative diary research on security trust and setup.
  • Recommendations for diagnostics, feedback, and understandable proof.
This case does not claim
  • No client identity, commercial launch, acquisition, or product-performance result.
  • No private technology, competitor comparison, or interface detail.

Rebuilding a self-service menu around customer language

Major U.S. bank · Client anonymized · Applause era

The existing voice menu made common tasks hard to find. Tree testing and card sorting moved the conversation from internal menu logic to the language customers used for self-service.

  • 17tree-test participants
  • 30card-sort participants
  • 26tasks categorized
  • 2recommended menu clusters
Read the full case study
  • RoleLead UX Researcher
  • GoalImprove task findability and language for a 24-hour self-service voice system.
  • MethodRemote tree testing plus open card sorting across 26 banking tasks.
  • ConstraintClient, internal menu artifacts, and the baseline failure percentage remain withheld pending public-use clearance.
01 / Hook
A self-service menu is only useful when people can find themselves in it.

The team was introducing new do-it-yourself options, but the existing structure did not match how customers grouped everyday banking tasks.

The turning point

Findability evidence showed that the problem was structural. Better labels inside the same menu would not be enough.

02 / Research
Test the tree, then ask customers to build a better one.
01
Tree testing

Remote sessions exposed where people expected to find common self-service options and where the current hierarchy failed them.

02
Open card sorting

Thirty participants grouped 26 tasks in their own language, making natural customer clusters visible.

03
Decision synthesis

The team received a clear rationale for changing the top-level structure rather than tuning individual prompts.

Research decision
Organize around what customers came to do, not how the organization described its services.

The evidence supported a simpler structure centered on self-service and money movement.

03 / Action
Turn findability evidence into a menu decision.
Recommendation
  • Restructure the menu around Self-Service and Money Movement clusters.
  • Use customer language as the basis for naming and grouping options.
Research value
  • Connected a known findability problem to a defensible structural change.
  • Provided both diagnostic and generative evidence for the same decision.
04 / Evidence boundary
What this case does and does not claim.
This case covers
  • Tree testing and card sorting for a self-service voice information architecture.
  • Evidence that informed a new top-level grouping model.
This case does not claim
  • No post-launch completion, handle-time, or company voice-AI outcome.
  • No internal IVR map, client name, or withheld baseline percentage.

A dashboard cannot earn trust on fragmented data

People analytics platform · Client anonymized · 2023 – 2024

Leaders wanted more proactive people analytics, but interviews showed they were still managing fragmented data and reactive workflows. A five-tier framework made the product tradeoffs visible.

  • 45 minsemi-structured interviews
  • 5framework tiers
  • 1roadmap decision model
Read the full case study
  • RoleUX Researcher
  • GoalAlign a people analytics roadmap with executive priorities and data realities.
  • MethodThirteen 45-minute interviews with HR, DEI, and talent leaders.
  • ConstraintClient, third-party systems, release details, and commercial results remain private.
01 / Setup
The opportunity was not another dashboard. It was a path from reactive data to useful action.

The team needed to understand how leaders used people analytics across a complex software ecosystem and where a product roadmap could create real value.

The turning point

Participants described a recurring constraint: fragmented historical data and integration gaps made advanced insights hard to trust.

02 / Research
Create a decision hierarchy before designing advanced features.
01
Leadership interviews

Conversations with HR, DEI, and talent leaders surfaced the difference between what teams wanted and what their data could support.

02
Five-tier framework

The Hierarchy of Needs moved from keeping the lights on through safety, efficiency, team health, and belonging.

03
Data integrity first

Research made the case for standardizing data before asking leaders to act on predictive signals.

Research decision
Proactive intelligence only matters when the underlying data deserves executive trust.

The roadmap moved from feature excitement to a staged sequence of integrity, visibility, and prediction.

03 / Action
Give leaders a path from signal to decision.
Recommendations
  • Standardize data integrity before leadership rollout.
  • Prioritize proactive alerts for retention deviations.
  • Use customizable headings and a unified dashboard to make insight easier to act on.
Research value
  • Created a shared framework for C-suite, product, and engineering tradeoffs.
  • Connected data quality to the credibility of predictive AI features.
04 / Evidence boundary
What this case does and does not claim.
This case covers
  • Strategic research, framework development, and recommendations for people analytics.
  • Data-integrity and predictive-alert tradeoffs from executive interviews.
This case does not claim
  • No released feature, adoption, retention, or revenue result.
  • No client, third-party platform, or proprietary data detail.

Why case studies matter

Strong work still needs a strong argument.

  • Case studies are crucial for landing interviews in a competitive market.
  • Weak studies can actively hurt your chances.
  • Memorable storytelling connects design decisions to business goals.
  • A portfolio with focused, credible studies builds confidence in your craft.

What compelling studies do

Answer the questions behind the hiring decision.

  • Frame it. Name the problem, user impact, and business relevance.
  • Prove it. Emphasize measurable outcomes, not output volume.
  • Connect it. Link the problem, your decisions, and the outcome.
  • Edit it. Aim for a focused read of less than five minutes.
The Minto Pyramid Principle

Lead with the answer. Then earn it.

Structure the story from the most important result down to the evidence. Open each layer to see what belongs there.

01 Start with the answer Present the single most impressive result first.
  • Include the timeframe and business impact.
  • Quantify the result with a key metric.
  • Connect the result directly to your contribution.
02 Support with key arguments Offer two or three insights that explain the result.
  • Show clear cause-and-effect relationships.
  • Include specific observations and supporting metrics.
  • Turn findings into actionable insights.
03 Provide additional clarity Use evidence to validate the argument and result.
  • Include the numbers and data that matter.
  • Explain testing methods and results, including A/B test specifics.
  • Make your methodical approach easy to follow.

Show your thinking. Validate your claims.

  • Explain the why behind decisions, not only the what.
  • Highlight the tradeoffs and challenges you navigated.
  • Back claims with research, analytics, and credible testing results.
  • Include implementation details and metrics when they add context.
  • Treat UX writing quality as part of the experience.

Avoid the familiar traps.

  • Don’t bury the point in an overly long process diary.
  • Don’t force every project into the same generic structure.
  • Focus on business impact, not a catalog of tools and workshops.
  • Write for hiring managers and answer their key questions.
  • Proofread carefully; the details signal how you work.
The wider portfolio

Choose proof that matches where you’re going.

  • Show functional UX work. Prioritize apps, platforms, and meaningful product flows over static pages.
  • Early career? Demonstrate industry-style experience and sound decision-making.
  • More senior? Consider a concise deck centered on the problem, influence, and impact.
  • At every level: quantify business benefits when you can and maintain a professional online presence.

The strongest case study is not the one with the most artifacts. It’s the one that makes your judgment, and its impact, easy to understand.

Mentorship

Research gets stronger when researchers do.

I mentor UX researchers through difficult study decisions, stakeholder dynamics, and career moves, the messy middle between knowing the craft and making it matter.

  • Sharpen the work

    Frame the decision, challenge the method, and find the clearest story in the evidence.

  • Build influence

    Connect findings to what stakeholders need to understand and decide next.

  • Navigate what's next

    Make career and portfolio choices with a practical, experienced sounding board.
