What I'm looking for

I’m looking for a React/TypeScript frontend role where I can lead SPA architecture, integrate REST APIs, improve performance, ensure accessibility, and ship quality-tested features in an Agile team.

I’m a Senior Frontend Developer with 7+ years of experience building scalable, high-performance web applications. I specialize in React.js, TypeScript, and Redux to deliver responsive Single Page Applications (SPAs) with complex state management, REST API integrations, and unit testing.

In healthcare and e-commerce/digital marketplace domains, I’ve led frontend architecture, implemented secure authentication and authorization UI, and optimized performance—improving application performance by 30%. I collaborate in Agile (Scrum) environments, ensure cross-browser compatibility and accessibility compliance, and mentor junior developers through code reviews.
