Piggy bank
UX / UI design
Google UX Certification Project
Project overview
PiggyBank is a financial literacy app designed to help adults build saving habits through goal-setting, progress tracking, and light gamification. This project was completed as part of the Google UX Design certification and represents my full end-to-end UX process — from user research and persona development through wireframing, prototyping, and usability testing.

The problem
Most financial apps overwhelm users with complexity before they've built any confidence with their money.
The opportunity wasn't to build a more powerful tool — it was to design a simpler, more human one. Research surfaced a consistent pattern: adults who struggled with saving weren't lacking willpower, they were lacking a clear starting point. The design challenge became: how do you make the first step feel achievable?
My role
Lead UX designer
As the Lead UX/UI Designer, I led the design process from research to final prototype, focusing on creating an intuitive and user-friendly interface. I conducted user research, developed personas, created wireframes, and high-fidelity prototypes, and conducted user testing.
Process
The UX/UI design process for the savings app involved user-centered research, iterative design, and user testing to create a functional and user-friendly product.
Research came first — and it reframed the entire project. Interviews with potential users revealed that the barrier to saving wasn't knowledge or tools, it was the feeling of not knowing where to start. That insight became the design's north star: every decision had to reduce friction at the entry point, not add features at the top.
From there I developed personas and journey maps to identify where existing apps were losing users emotionally, not just functionally. Wireframes were built around those drop-off moments, tested early with real users, and iterated based on what they actually did — not just what they said. The prototype went through two rounds of usability testing before reaching high fidelity, with each round tightening the onboarding flow and the goal-setting experience specifically.
The solution
An app that offers a personalized, goal-based savings structure with a visually appealing interface, gamification elements, and an intuitive design.
PiggyBank provides users with a personalized, goal-based savings experience. The app features a clear, visually appealing dashboard that tracks savings progress, sets custom goals, and provides motivational prompts. Gamification elements, such as earning badges for achieving milestones, help keep users engaged and motivated. The clean, minimalist UI ensures an intuitive experience, making the app accessible even to users with limited financial knowledge.
What I learned
This project sharpened my understanding of where UX and behavior design intersect.
Designing for motivation is different from designing for usability — a user can understand exactly how to use a feature and still not use it. The gamification elements (milestone badges, visual progress indicators) weren't decorative decisions; they were responses to a specific research insight about how users emotionally disengage when progress feels invisible. Testing validated this: users who saw visual savings progress in early prototypes reported feeling more "in control" — a word that came up unprompted across multiple sessions.
