My story

I'm Vinay Singh Chaudhary, a student of the BS in Data Science & Applications at IIT Madras. I have completed the Foundation level and both Diplomas — Programming and Data Science — and I'm now working through the Degree level.

I enjoy the full journey of data: collecting it, modelling it, and turning it into something people can use. That has taken me from Kaggle-style ML competitions and a real-business analytics capstone to production-style web apps (Flask, Vue, Celery, Redis) and autonomous LLM agents built with LangGraph and Gemini.

In September 2026 I became a Microsoft Certified: Fabric Analytics Engineer Associate (DP-600), which grounded my interest in modern data platforms — OneLake, Delta Lake, medallion architecture and semantic models in Power BI.

Outside code I love teaching and tech education, creating content, and contributing to open source. I'm looking for opportunities where I can learn fast, ship real products and grow as a data/AI engineer.
