Neeraj Chormale

AI/ML engineer & backend developer

I build the part of AI that has to actually ship — agents, retrieval pipelines, and the infrastructure underneath them. These days I work mostly in Python and FastAPI, on top of Neo4j knowledge graphs and Milvus vector search, with LangGraph holding the orchestration together.

Currently a final-year CSE student, building Usebox at Toshal Infotech.

01 Work

Python AI/ML Intern, Toshal Infotech

2026

Building Usebox, an AI tutor that teaches business users AI concepts through conversation and then generates hands-on labs pitched at their level. I architected the Neo4j knowledge graph that lets it do multi-hop reasoning a flat vector store can't, and the Milvus RAG layer that keeps answers grounded in real source material instead of guessing.

AI Intern, iLink Digital

2025

Built an Intern Companion Agent in Copilot Studio and an attendance portal in Power Apps, then wired the two together so they ran as one workflow for the intern programme. Also pitched in on UI for the team's Power Apps projects.

2024

Rebuilt the company's WordPress storefront — cart, wishlist, inventory — and put in the SEO groundwork that took organic traffic from roughly 130 to 2,500 visitors a month over the summer.

Data Center Cooling Optimization

GitHub

A custom Gymnasium environment that models a multi-zone data centre — thermal dynamics, power draw, the lot — where a Soft Actor-Critic agent learns continuous cooling control while keeping every zone in bounds. Comes with live temperature, power and reward plots so runs are actually reproducible across seeds.

IronLog

GitHub

An offline-first PWA for logging workouts and tracking splits across the week. Mobile-first, installable straight from the browser, with local storage and sync so it works with no signal in the gym.

ReWatch

GitHub

A content-based recommender for wristwatches. It engineers features from both structured fields and free text — one-hot, scaling, TF-IDF — and matches taste with cosine similarity.
