What I'm looking for

I seek frontend roles focused on React/Next.js with opportunities to integrate AI, improve performance, and work in collaborative cross-functional teams; open to remote or on-site, immediate joiner.

I am a Frontend Software Engineer with 2.7 years building scalable, SEO-optimized web applications using React, Next.js, and TypeScript.

I design reusable component systems, improve performance through SSR/SSG/ISR, code splitting and lazy loading, and ensure responsive, accessible UIs across browsers.

I have hands-on experience integrating AI APIs (OpenAI, Gemini, Claude) to automate workflows and enhance user experience, delivering measurable improvements in load times and retention.

I collaborate closely with backend and AI teams, lead feature architecture in cross-functional teams, and consistently ship production-ready pages and components that reduce development time and bug reopens.
