What I'm looking for

I seek collaborative teams building user-focused mobile or web products, with opportunities to modernize stacks, mentor peers, and grow into full‑stack or platform roles.

I am a results-driven mobile and web developer with a background in React, React Native, and JavaScript-based back-ends. I build performant, maintainable applications and focus on improving code quality through testing and reviews.

My experience includes migrating and modernizing frontends — notably rewriting Angular apps into React — and transitioning mobile apps from Cordova to React Native to boost performance and scalability. I also implement back-end endpoints and PostgreSQL queries using Express.js.

I have contributed to cross-functional teams at TomTom, Venture IQ, and Elements, taking part in feature development, unit and end-to-end testing, bug fixing, and peer code reviews. I help teammates adopt new technologies and improve team workflows.

I bring a practical full-stack perspective supported by formal coding education and freelance experience building web solutions for small businesses. I prioritize collaboration, clean code, and shipping reliable user-focused products.
