What I'm looking for

I seek a collaborative, learning-focused team where I can own front-end features, apply best practices, and drive practical, high-impact solutions.

I am a frontend developer specializing in React, Next.js and TypeScript, experienced in building and scaling modern web applications for healthcare and e-commerce. I lead migrations, design reusable component systems, implement role-based access control, and optimize data fetching to improve performance and reliability.

I've reduced page load times, cut API traffic, and lowered production bugs through testing and refactors, while collaborating closely with product and design in Agile teams. I seek a team that values continuous learning and best practices where I can own key features and deliver practical solutions.
