What I'm looking for

I seek frontend-focused roles where I can drive modern web architecture, mentor teams, work on UX-centric products, and modernize legacy systems in collaborative settings.

I am a Senior Frontend Developer with over five years of experience building Angular and React applications, mentoring junior developers, and bridging frontend and backend concerns to deliver scalable, performant solutions. I have led migrations of legacy apps to modern stacks, implemented cross-platform delivery with Tauri and Ionic, and contributed to enterprise projects for major clients.

My background includes full-stack exposure from early backend work in C#, .NET, SQL and WPF, which informs my pragmatic approach to API integration and architecture. I prioritize user-centred design, clean code, and collaboration, and I enjoy designing UX mockups and improving developer workflows through upgrades and refactors.
