What I'm looking for

I’m looking for a team where I can own end-to-end React Native/React features, collaborate in an agile environment, and ship scalable, high-performance experiences that balance clean code, great UI/UX, and measurable business impact.

I’m a Front-End Engineer with 3+ years of experience delivering end-to-end, high-performance mobile and web applications. I build user-centric solutions in React Native and React.js, integrating complex features with secure authentication, role-based access control, and maintainable state management.

Across remote and freelance work, I’ve shipped cross-platform products supporting 5,000+ active users, integrated 20+ REST APIs, and improved operational efficiency by up to 30%. I also use AI-assisted workflows (Cursor, Claude, and MCP) to speed development while keeping code consistency, performance stability, and a polished UI/UX.
