About

Product-minded engineering with strong visual taste.

I combine frontend craft, backend practicality, and disciplined delivery to ship products that feel modern, useful, and ready for real users.

I lead delivery across product, design, and engineering at Tallen Tech — building mobile and web software that ships on time, works in production, and earns user trust.

My work across agriculture, healthcare, and e-commerce taught me that great products need more than good code. They need clear interfaces, stable architecture, and someone who owns the outcome end to end.

How I Work

Design clarity, stable engineering, and release discipline.

  • Design systems that feel modern without sacrificing clarity
  • Architecture decisions that keep teams fast after launch
  • Code review, refactoring, and release quality as delivery habits

Sector Fluency

Built for teams solving operational problems, not just demos.

How I Help

Three ways I can move your product forward.

Whether you need a new mobile app, a better web presence, or someone to clean up what you already have — here's how I work with teams.

Start a Conversation

Mobile App Delivery

Cross-platform mobile apps built with React Native and Expo — from initial architecture through App Store and Play Store release.

UI Polish & Refactoring

Take an existing app or codebase and make it feel finished — cleaner interfaces, better component architecture, and faster iteration cycles.

Experience

Leading delivery, not just contributing code.

My current role combines hands-on implementation with architecture decisions, code review, product execution, and team direction.
