What I'm looking for

I seek a full-time senior/lead frontend role where I can drive architecture, mentor engineers, collaborate on UI/UX, and optimize high-performance web and mobile products.

I am a frontend developer with over a decade of experience designing and building web and server-side applications, focused on high-performance React and React Native solutions. I lead architecture, create features, optimize performance, perform code reviews, and mentor team members.

At my current role I designed a modular core + web + mobile architecture for a customizable multi-asset trading platform, enabling very high-frequency UI updates and coordinated web and mobile experiences. I collaborate closely with designers to ensure strong UI/UX and product alignment.

I have led small frontend teams, participated in hiring and task management, built microservice ecosystems, and implemented SEO-friendly interactive landing systems, AMP pages, and adaptive mapping services. I consistently drive performance improvements and maintainable architectures.
