Frontend developer building React products with end-to-end ownership and performance focus.
IndiaWhat I'm looking for
I’m a Frontend Developer who’s built and owned user-facing experiences end-to-end for Brand Kiln’s AI recruitment platform, TalentForce X. As the sole frontend developer for TalentForce X, I take features from design through production, shipping across a large surface area of pages and components.
Earlier, as a React Developer at Arthalab Solutions, I architected and implemented 80% of frontend components for a high-traffic marketing application. I improved performance with lazy loading and code splitting (55% reduced initial load time), built an API integration layer that lowered backend processing load by 30%, and used UI analytics to increase retention by 35%.
During my Frontend internship at LiftU.Tech, I optimized a test-taking platform by implementing server-side rendering with Next.js, improving page load speeds by 40%. I’m energized by building polished UI/UX, integrating secure payments, and setting up reliable CI/CD pipelines—always with accessibility, responsiveness, and measurable outcomes in mind.
