Data analytics and GenAI engineer building ML/DL APIs .
IndiaWhat I'm looking for
I’ve spent 10.6 years working with Python, Pandas, NumPy, OOPS, Scikit, and visualization libraries, and I’ve focused on delivering data solutions that ship. On the GenAI side, I’ve worked with LLMs and tooling like LangChain/LlamaIndex, plus Copilot, Claude, and Gemini.
Most recently, at Tenjiku-Equities (Senior Quant Analyst), I designed and optimized Python backend systems with FastAPI, Pydantic v2, and Loguru for scalable ML/DL deployment. I built data pipelines with Pandas, NumPy, and DuckDB, and developed interactive Plotly dashboards for trading insights, then delivered production-ready APIs for trading and risk workflows.
Before that, I trained and developed in Python/AI roles at HCL GUVI, PW-Skills, and delivered data-science/GenAI programming for clients through Alchemy solution PVT.Ltd (Vodafone) and IWS (Airtel). I’ve also handled Linux security and web infrastructure/security work earlier in my career, combining Python with VAPT tools and Bash scripting.
