Turning Ideas into Production Code

A developer who ships. From concept to deployment, I build things that work.

Hey, I'm Raghu 👋

I'm a Computer Science student at IIIT Delhi with hands-on experience building and shipping real products. From deploying CampusPYQ — a platform serving active users — to building enterprise-grade GenAI chat systems at Alpine Privacy, I focus on creating software that actually works in production.

My sweet spot is at the intersection of full-stack development and AI. I've designed RAG architectures for document querying, fine-tuned ASR models for low-resource Indian languages under the Bhashini government initiative, and built everything from donation management systems to faculty admin portals.

I believe in shipping fast, communicating clearly, and writing code that's maintainable long after the project ends.
