A mobile app for traffic enforcement officers working roadside, where every interaction has to survive real field conditions: one hand free, poor light, and a driver waiting. The core challenge was compressing a slow paper process into a few taps: look up a plate, see the vehicle and owner record, check whether fines are settled, and issue a violation on the spot with photo evidence attached.
I designed 84 screens across 16 flows in Figma, covering layered authentication (password, biometric, and 2FA officers carry sensitive records), a patrol dashboard with paid/unpaid status at a glance, plate search with full result states, violation creation and reporting, evidence capture with media upload, and outcome states like ID collected and vehicle impounded. The interface leans on a calm navy system with high-contrast status colours, so payment state and violation severity read instantly without an officer having to stop and interpret the screen.

A mobile app design for FieldSync, a data-collection tool built for field enumerators, the people gathering survey and census data on the ground. The core challenge was designing for real working conditions: fast, low-friction data entry, clear navigation for non-technical users, and a clean interface that stays legible in the field. I designed the full experience in Figma, from a focused onboarding and login flow to the data-capture screens, using a calm, high-contrast visual system that keeps the focus on the task. The result is a purpose-built product UI that makes collecting accurate data quick and simple.

A complete website design and build for Growth Mindset Learning Foundation, an NGO focused on early childhood education and family well-being.
I designed the full experience in Figma, a warm, trustworthy visual system with a clear content structure across Home, Programs, Impact, and Get Involved, and then built it out with integrated donation functionality so supporters can give directly on the site.
The result is a clean, credible, mobile-responsive presence that helps the foundation tell its story and convert visitors into donors.
