About

Full stack, end to end.

I'm a full stack developer focused on the MERN stack and scalable backend systems. Across roles at Invoidea, Truwix, GlobalLogic, and Dehix, I've built and maintained production platforms spanning HR, commerce, property, and education.

My work leans on modular Node.js and Express APIs, message queues and caching with RabbitMQ and Redis, and pragmatic use of cloud infrastructure. More recently I've worked on GenAI tooling — local LLM inference and retrieval-augmented workflows for security log analysis.

I care about systems that keep working after the demo: measurable performance, clear architecture, and code that the next person can reason about.

Principles

How I approach the work.

01Build for production
02Keep systems simple
03Measure before optimizing
04Design for scale

Contact

Let's build something that ships.

Open to full stack and backend roles, and interesting problems in between. The fastest way to reach me is email.
