πŸ‘©β€πŸ’» About Me

ML Engineer Β· AI Architect Β· Agentic AI Builder

πŸ“ Bangalore, India

I build AI that drives real business outcomes β€” not demos, not POCs. I work across domains β€” from marketing intelligence and finance to consumer apps β€” wherever there's a hard problem that AI can genuinely solve. Specialising in RAG Systems Β· Multi-Agent Workflows Β· Predictive ML Β· Full-Stack AI Apps.

AI-native by design: I compress 6-month roadmaps into 6-week deliveries using LLMs, vector search, and agentic frameworks.

πŸ”§ Open Source Contributor: statsmodels Β· SciPy Β· Microsoft AutoGen Β· LangChain Β· featuretools

πŸ“© If you're hiring for Senior ML / AI Architect / GenAI roles β€” I ship fast, think in systems, and make AI work for your business. Let's talk.
