What I'm looking for

I seek roles where I can lead frontend/mobile development, drive technical quality, mentor teams, and deliver scalable user-centered products in agile environments.

I am a driven senior software engineer specializing in frontend development with extensive experience in React, React Native, Angular and Node.js. I lead technical projects, deliver user-centered applications, and have improved product adoption and delivery outcomes across hospitality, project management, and logistics sectors.

I have repeatedly acted as technical lead and sole mobile developer on projects, mentoring junior engineers, enforcing code quality with strict reviews and testing (Jest), and deploying solutions using AWS, CI/CD and agile practices. My background includes international experience in Europe and the US markets and a track record of scalable component design and API integration.
