What I'm looking for

I'm seeking front-end roles where I can build performant, responsive React/Next.js apps, solve UI performance challenges, work with cross-functional teams, and grow in animation and real-time features.

I am a Frontend Developer with 4+ years of experience building responsive, high-performance web applications using React, Next.js, TypeScript and Tailwind CSS. I focus on polished UI, smooth animations, and performant real-time features that keep users engaged.

At my current role I implemented real-time chat with Supabase, replaced Axios with Fetch for performance gains, and built complex interfaces like a Supervisor Inbox and Flow Generator with centralized state (Zustand), advanced filtering, animations and scalable component structures. I added features such as undo/redo, drag-and-drop, multi-select, MDX live preview, and light/dark themes while maintaining version control and CI/CD practices.

I also deliver client-facing projects and portfolio apps—ranging from 3D integrations to secure auth systems—and hold certifications in JavaScript and responsive web design; I enjoy debugging, collaborating with designers, and continuously improving developer experience.
