I’m a Full Stack Engineer who builds end-to-end products with a strong bias toward clean architecture, typed implementations, and reliable delivery. I’ve designed and shipped user-facing systems and internal tooling, from authentication and onboarding to end-to-end payment and enrollment flows.

Most recently, I architected ElevIQ from scratch, selecting the stack (React, TypeScript, Node.js, Express) and delivering scalable foundations as the team grew. I implemented session-based HTTPS cookie authentication with OAuth, authored onboarding documentation, and mentored engineers through structured PR reviews and branch protection practices.

On the Medicoed side, I built a large-scale OPD clinical simulation with a scoring engine powered by semantic similarity and LLM evaluation. I also designed RAG pipelines that parse and chunk large medical PDFs, store metadata-rich typed records, and enable hallucination-free retrieval for high-stakes content.

I thrive in real-time and AI-heavy builds, like recreating a research chat room with UI overhaul, file transfer, and re-architected video conferencing using LiveKit’s SFU model for 10+ concurrent participants. I’m comfortable with deployment and operations too—Dockerized services, shipped CI/CD with GitHub Actions, deployed to GCP, and ported apps to Android and iOS via Capacitor.
