What I'm looking for

I seek front-end roles where I can build performant, accessible UI with React/Next.js, collaborate with designers and backend teams, and grow into technical leadership.

I am a Front-End Engineer focused on building clean, accessible, and high-performance user interfaces using Next.js, React, TypeScript, and Tailwind CSS. I take complex product ideas and turn them into responsive, pixel-perfect web experiences.

At Lagetronix I pioneered high-performance web interfaces with Next.js, authored 15+ modular TypeScript components, and connected 25+ third-party APIs to enable real-time features. My work improved page load speed by 30% and sped feature delivery by 25%.

Previously at Pro-Ice Limited and Lexjon Technologies I refactored legacy UI codebases, built 11+ interactive apps, and implemented reusable components and state management patterns that reduced bugs and re-renders significantly. I consistently delivered cross-browser compatible, responsive layouts and integrated numerous RESTful APIs.

I collaborate closely with designers and backend teams to align UI architecture and data flow, emphasize performance optimizations like code-splitting and lazy loading, and maintain a strong focus on developer ergonomics and product outcomes.
