What I'm looking for

I’m looking to build and ship end-to-end products across web and mobile, using Next.js/Node.js and AI automation (OpenAI, RAG, agentic workflows). I want a team that values clean architecture, fast iteration, and reliable deployment.

I’m a Senior Full-Stack Engineer with 5+ years building production-grade web and mobile applications across healthcare, AI automation, and Internal Tools. I focus on shipping end-to-end—from architecture through deployment—so products work reliably in real-world workflows.

I’ve delivered pixel-perfect redesigns and modernized legacy experiences using Next.js and design-to-development execution based on Figma. I also build agenticAI solutions, including an AI room-booking chatbot that uses OpenAI with MongoDB Atlas Vector Search to support natural conversation and knowledge-base querying.

On the product side, I’ve shipped cross-platform mobile apps and feature updates—building iOS MVPs with Expo, implementing biometric login, and improving healthcare communication experiences used by thousands of medical professionals. I’m comfortable spanning frontend polish, REST API integration, and debugging high-impact issues.

From MERN-stack e-commerce and POS systems to AI-driven tools, I’ve implemented authentication, role-based access control, third-party API integrations, and payment workflows. I bring a practical engineering mindset—clean APIs, scalable databases, and CI/CD-backed deployments on AWS and cloud infrastructure.
