What I'm looking for

Looking for a Full Stack Developer / Frontend Engineer role focused on React, Next.js, TypeScript, and modern web technologies. Interested in building scalable applications, solving complex technical challenges, and contributing to high-impact products while continuing to grow as a software engineer.

I’m a senior full-stack developer focused on delivering production-grade web applications end-to-end—architecture decisions, API contracts, code quality, and team velocity. Over 6 years, I’ve built and led frontend and backend work in fintech and enterprise banking, with a strong emphasis on performance and maintainable system design.

At TCS, I was the sole frontend architect of a B2B workflow platform serving 10,000+ APAC internal users. I redesigned the UI from a page-per-feature monolith to a shared component system, established internal documentation and standards, and improved caching and code-splitting performance—plus mentored a team of engineers through weekly reviews.

At Capgemini (Barclays), I architected and led a greenfield migration from a Django-template monolith to a React 18 + Vite micro-frontend SPA. I reduced page load from ~4s to ~1.1s, cut release cycle time by 40%, shipped 12 production REST APIs with JWT auth and RBAC, optimized Oracle-backed query performance, and supported adoption of tooling like GitLab Duo AI.
