What I'm looking for

I seek senior roles building production GenAI/ML systems with strong Responsible AI practices, measurable ROI, and cross-functional collaboration.

I am a Senior AI/ML engineer with 12 years of experience building production machine-learning and GenAI systems, focused on LLMs, RAG, agentic workflows, and scalable inference. I have launched enterprise GenAI assistants for audit, tax, and customer support that achieved roughly 70% autonomous resolution and drastically reduced response times.

My work spans recommendation engines, multilingual virtual agents, and enterprise data platforms; notable results include a recommendation engine that increased CTR by 60% and revenue per visitor by 10%, and automation initiatives that cut routine query handling by ~70%. I design domain-governed RAG stacks, implement privacy and Responsible AI guardrails, and productionize low-latency endpoints with measurable ROI dashboards.

I partner with product and stakeholder teams to drive adoption and mentor engineers, bringing hands-on expertise in FastAPI, LangChain/LangGraph, Hugging Face, vector databases, and cloud deployment to deliver safe, auditable, and high-performance AI solutions.
