I build the part of AI that has to actually ship — agents, retrieval pipelines, and the infrastructure underneath them.

About

I care about what happens after the demo.

I'm a final-year CSE student and AI/ML engineer based in Pune, working mostly in Python and FastAPI. I build agents and retrieval pipelines on Neo4j knowledge graphs and Milvus vector search, with LangGraph holding the orchestration together.

What I enjoy is the unglamorous infrastructure — the part that turns a slick demo into something grounded, reproducible, and ready to put in front of real users.

Experience

Where I've worked.

Jan 2026 — Jun 2026 Surat, India

Python AI/ML Intern

Toshal Infotech

  • Architected a Neo4j knowledge graph for multi-hop reasoning a flat vector store can't do, structuring AI concepts and their relationships.
  • Built the Milvus RAG layer that keeps answers grounded in real source material and cuts hallucinations on out-of-distribution questions.
  • Shipping Usebox — an AI tutor that teaches business users AI concepts through conversation, then auto-generates hands-on labs at their level.

Things I've built.

Data Center Cooling Optimization

A reinforcement-learning agent that learns continuous cooling control for a multi-zone data centre — holding every zone in bounds while cutting power. A custom Gymnasium environment models the thermal dynamics; a Soft Actor-Critic agent learns the policy.

IronLog

An offline-first PWA for logging workouts and tracking splits — installable, mobile-first, and works with no signal in the gym. Persistent local storage with sync, plus a clean UI for managing exercises, sets, reps, and rest.
