What I'm looking for

I’m looking for full-stack, frontend, backend, or API-integration roles where I can ship production systems—React/Next.js UIs, REST APIs, AWS deployments, and AI/LLM integrations—with clean architecture and strong ownership.

I’m a Full Stack Developer with 3+ years of experience building scalable, production-ready web applications end-to-end—from database architecture and REST APIs to responsive, high-performance frontends. I focus on clean architecture, strong ownership, and shipping reliable products.

In my recent role, I designed and developed full-stack apps with React.js and Next.js, and built backend services with FastAPI and Express.js using PostgreSQL and MongoDB. I implemented secure JWT authentication, query optimization, and schema design—then deployed and maintained AWS infrastructure with Docker and GitHub Actions CI/CD, sustaining 99%+ system uptime.

I also integrate AI/LLM APIs (OpenAI, Gemini, Claude) into production workflows to automate data processing and reporting, reducing manual workload by 40%+. With automated validation pipelines and backend reconciliation, I improved data accuracy by 20%+, and I enjoy collaborating cross-functionally to deliver smooth, reliable product experiences.
