What I'm looking for

I want to build React-powered, high-performance SPAs in an Agile/Scrum team—owning frontend architecture, performance, and testing. I’m excited to work on complex API integrations, real-time features, and accessible, pixel-perfect UI with measurable impact.

I’m a Frontend Developer with 5+ years of experience building scalable, high-performance Single Page Applications (SPAs) for enterprise clients. I focus on measurable outcomes—improving performance by up to 40%, reducing defects by 25%, and accelerating feature delivery.

Across healthcare, logistics, e-commerce, insurance, and public safety, I’ve shipped React.js solutions using Redux Toolkit, TypeScript, and modern JavaScript (ES6+). I’ve integrated REST and GraphQL (Apollo Client), implemented JWT authentication with silent token refresh, and built real-time experiences using WebSocket/Socket.io—always with attention to reliability and smooth user sessions.

I also strengthen quality and maintainability through CI/CD practices, Jest and React Testing Library, and code-quality habits like ESLint. From route-level code splitting and virtualization to accessible UI with Semantic HTML and ARIA roles, I consistently turn designs into pixel-perfect, production-ready interfaces.
