What I'm looking for

I’m looking to build end-to-end production web applications—scalable APIs, secure auth, and AI-powered features—while owning real-time workflows, clean deployment pipelines, and high-quality automated testing.

I’m a Full Stack Software Engineer with over two years of professional experience building and shipping production web applications end-to-end. I specialize in TypeScript, React/Next.js, Python/FastAPI, PostgreSQL, and AWS, and I enjoy turning complex product ideas into reliable systems.

In my recent work, I built a full EdTech ERP and created a biometric attendance pipeline that eliminated manual roll-call entry. I also engineered automated grade computation, an AI-powered OMR checker, and an institutional RAG chatbot using LangChain and vector search.

I’ve shipped scalable, secure full-stack features remotely as well—building Next.js/TypeScript production applications with JWT authentication and RBAC, performance-focused architecture, and safe Stripe payment flows. Across both roles, I containerize services with Docker, automate CI/CD to AWS/Vercel, and support production quality with comprehensive Jest/Pytest coverage.
