About Me
Hi, I’m Dat Nghiem — a UX/UI designer passionate about crafting inclusive, intuitive digital experiences that serve real people with diverse needs. With a strong foundation in user research, wireframing, prototyping, and front-end development, I approach each project with empathy, clarity, and a focus on usability. Accessibility isn’t an afterthought — it’s a core part of how I design. I believe inclusive design is not only ethical, but essential to innovation. From early research to final implementation, I advocate for solutions that empower users of all abilities and create a more equitable digital world. I’m experienced in collaborating with cross-functional teams, running usability tests, and translating complex problems into clear, user-centered interfaces. I'm comfortable working across tools like Figma, Webflow, Adobe Creative Suite, and writing clean HTML/CSS when needed. When I’m not designing, you can find me exploring design systems, refining portfolio case studies, or bringing playful ideas to life in Webflow. Let’s build experiences that are both beautiful and inclusive — together.

Data analytics NS

Analytics play a crucial role in optimizing the Build Your Own Plan questionnaire and increasing conversion rates. By tracking user behavior, drop-off points, and engagement metrics, we can identify where users lose interest or abandon the process. A/B testing different question formats, layouts, and CTA placements helps refine the experience for higher engagement. Heatmaps and session recordings provide insights into navigation patterns, allowing for UI improvements that enhance clarity and ease of use. Additionally, analyzing conversion funnel data helps pinpoint which steps lead to the most successful sign-ups, enabling data-driven optimizations that make the journey more seamless, personalized, and effective.

Data Analytics NS 2

Monitoring daily user engagement is crucial for understanding how users interact with the app and identifying areas for improvement. By analyzing active users, session duration, feature interactions, and drop-off points, we gain insights into what keeps users engaged and where they face friction. This data helps optimize the Build Your Own Plan questionnaire, refine the UI, and enhance overall user experience. Higher engagement directly correlates with increased conversions, customer retention, and long-term success, making daily tracking an essential tool for continuous app improvement.

UBS

Project Goal

UBS wanted to design a new vision for their Consumer Facing Products. I was designer in a team of 3 people. The project was broken into two phases and lasted over 7 months. I communicated with stake holders and helped lead the team, which included 2 other Senior UX Designers.In phase 1 we delivered a design language that demonstrated across several products. Phase 2, we dove into the experience of the products, focussing on navigation, search, and notifications. Both phases used heavy usability testing, analysis, and iteration.My core responsibilities included design, design strategy, , field research, prototyping, usability testing, and presenting work to clients.Core deliverables for the project:
-Design language with 400+ components
-UX/UI documentation
-Hi-fidelity product designs
-70+ interviews and usability tests with stakeholders and users
-10+ prototypes illustrating hero flows and use cases
-30 person workshop with key stakeholders
-Design research deck
-3 online Usability Hub tests delivered to 150 participants

Deliverables

Design Research

We spent the first few weeks of the program immersing ourselves in the environment. We interviewed Financial Advisors (FAs) and Customer Service Advisors (CSAs) from four different UBS locations at their desks to watch them use their current tools.

Job overview

I was the only UX designer that had 2 teams at Power HRG. One team focused on supporting accounting and the other corporate finance. I led over 20 different projects and successfully launched them.

Research & Analysis

Initially I developed a list of questions to identify what works and what doesn’t for our users. These questions were specifically designed to find the “bread and butter” of what users log into the application for. Ex.What device do you use most when using the app?How often do you log onto the app?What are you typically looking for when you’re on the app?Do you navigate to other pages to find your data?I also included a couple of usability tests to determine the pain-points for users when navigating throughout the app.

Power Statistics
After gathering data form the feedback and tests I was able to analyze the “MVP” of the application. Users are typically logging on the app through their phone every morning and when they are out on appointments. They’re typically looking for their financial status and their previous appointment statuses
Whiteboard and Sketching
Power Whiteboard
I presented my data, partnered up with the lead developer and project manager to develop the architecture of “SalesBook”. The data led me in the direction of making this a mobile first experience. After finishing up the creation of a persona and user flow, I started sketching out 7 different iterations and had my ux team vote to narrow down the best version.

UX Research Portfolio: Data-Driven Insights from Meal Delivery Prototype Testing

Role

UX Research/ Data Analyst

Company

Jenny Craig

Project Overview

This UX research project analyzed user testing of a meal delivery service prototype, focusing on non-customers (female, aged 45–50). Using data analytics, I identified user behaviors, preferences, and pain points to improve the user experience. The prototype included a homepage (HP), secondary page (SP), related content sections (RCs), and Club Advantage (CA) membership.

Methodology

🎯

Objective

Uncover non-customer insights for meal plan comprehension and value perception.

👥

Users

10 females, 45–50, never purchased NS before

🛠

Tools

Google Sheets · GPT-4 · Miro · Userlytics · Figma

📈

Focus Area

Meal plan clarity, pricing, and brand differentiation

Key Findings

Data analytics uncovered critical insights:

  • Meal Quantity Focus: 100% of users prioritized meal counts over other benefits. 60% struggled to identify quantities due to unclear presentation.
  • Pricing Clarity Issues: 70% found pricing ambiguous, with 50% unsure if prices were weekly or monthly. 40% miscalculated HP/LC meals, assuming one meal/day.
  • Club Advantage Confusion: 80% were confused by CA’s inclusion as a “plan,” with 60% unclear about its $70 base price and meal model.
  • Plan Differentiation: Only 30% initially understood HP/LC vs. JC differences. After prompting, 90% identified distinctions, but branding had no impact.
  • Visual Appeal: 100% appreciated food photos and nutritional callouts. All scrolled plan cards, but only 40% recognized four distinct plans.
  • Program Perception: 80% viewed the Program as comprehensive (3 meals/day, 7 days/week). Only 20% noted its regimented structure.

Recommendations

Based on quantitative and qualitative analysis, the following UX improvements are proposed:

  • Highlight Meal Quantities: Use numeric digits (e.g., “3 meals/day”) on SP and RCs to reduce 60% confusion.
  • Clarify Pricing: Add time references (e.g., “per week”) to SP prices, addressing 70% of concerns.
  • Redesign CA: Visually separate CA from meal plans to clarify its membership model, reducing 80% confusion.
  • Simplify Plans: Use icons or tables to highlight HP/LC, JC, and Program differences, improving comprehension beyond 30%.
  • Strengthen CTAs: Replace CA’s “Select Meals” with “Explore Meals” to boost engagement (0% engaged in prototype).
  • Expand FAQs: Address delivery, meal freshness, and logistics, as 50% sought more details.

Impact

Implementing these recommendations is expected to:

  • Reduce user confusion by at least 50% for meal quantities and pricing.
  • Increase plan selection confidence, particularly for CA, by clarifying its value.
  • Enhance conversion rates by streamlining decision-making for busy, health-conscious users.

Conclusion

This project showcases my ability to leverage data analytics in UX research, quantifying user feedback (e.g., 80% CA confusion) to deliver actionable insights. The recommendations enhance clarity, navigation, and trust, creating an intuitive experience for the target audience.

Company

Nutrisystem

Project Overview

Goal: Improve user engagement and content discoverability on a high-traffic marketing website.
Tools: Google Analytics 4 , Heatmaps (Clarity), UX heuristics

Analytics-Driven Discovery
Summary Metrics
  • Active users dropped by 16.6% and engagement time by 18.2%, signaling potential content fatigue or slower page loads.
  • ‍New user percentage increased by 10.4%, but engagement dropped, indicating poor first impressions or irrelevant landing experiences.
Trends
  • Spikes around late Feb and end of May suggested campaign impacts.
  • These were aligned with specific marketing pushes — but did not lead to sustained engagement.

Key Findings

UX Decisions Based on Device and Region Insights

  • 54.1% of users were on mobile, yet mobile experience had longer load times and more friction in event flows (scroll, CTA taps).
  • Chrome on Android dominated browser/OS combos → Focused testing on that environment.
  • Top geographies: U.S. was leading, followed by untagged traffic ("not set") — prompted improved UTM tagging for email/social campaig

Event-Level Behavioral Insights

  • Page views vs item list views were nearly equal → Users skim product listings but often don't go deeper.
  • User engagement was only 5.4% of total events → Indicated need for more interactive content or clearer calls to action (CTAs).
  • Scroll depth was low → I redesigned the homepage to surface more value above the fold and simplified nav structure.

Event-Level Behavioral Insights

  • The homepage (/) captures 58% of sessions but has a 46.7% bounce rate.
  • The “(not set)” landing page also draws significant traffic (50%) but with a 99.5% bounce rate, likely caused by misattributed or broken campaign links.
  • Audited tracking issues for “(not set)” to properly route attribution.

Event-Level Behavioral Insights

  • Conversion spikes are rare and inconsistent, with most days seeing low purchase volumes.
  • The “(not set)” landing page also draws significant traffic (50%) but with a 99.5% bounce rate, likely caused by misattributed or broken campaign links.

Recommendations

Based on quantitative and qualitative analysis, the following UX improvements are proposed:

  • Content Reprioritization: Above-the-fold redesign to match high-interest content from view_item_list trends.
  • Mobile Optimization: Reduced hero image size and decluttered UI for faster load and easier navigation.
  • Behavior Tracking: Added custom GA4 events for CTA clicks and exit intent on mobile.
  • The highest peak (~700 purchases) occurred late February, possibly linked to a promo or campaign (worth replicating).
  • Suggested A/B testing hero sections and simplifying above-the-fold content on the homepage to reduce bounce.
  • Optimized /shop/apparel subpages with better filtering and product previews.
  • Recommended aligning UI changes with campaign schedules (e.g., updating hero banners or promo sections).
  • Proposed adding urgency indicators (like countdown timers or “limited stock” badges) on product pages to lift conversions.
