The Shinobi's Path

AI & Data Science graduate from Saveetha University (SIMATS). I build production-grade intelligent systems — LLM-powered tools, RAG pipelines, ML classifiers, and full-stack analytics dashboards.

13 projects shipped. All open-source. All working. From code review assistants to interview coaches to live stock dashboards — each one solves a real problem.

Cisco & networking certified. Internship-tested at Orion EdTech. Presented at IIT Chennai and SIMATS Tech Star Summit. Currently open to work.
