What I'm looking for

I seek roles building production GenAI/LLM systems with strong MLOps, low-latency inference, multi-cloud deployment, and collaborative engineering culture.

I am a Senior Machine Learning Engineer with over 10 years building production-grade AI/ML systems across NLP, computer vision, and time-series forecasting. I design and deploy LLM-driven solutions, RAG pipelines, and low-latency inference stacks using tools like Triton, ONNX, and multi-cloud GPU infrastructure.

My work spans fine-tuning and quantization (LoRA, QLoRA, 4-bit/8-bit), building MLOps ecosystems with CI/CD, monitoring, and auto-scaling, and integrating retrieval systems using LangChain, FAISS, and Pinecone. I have driven measurable improvements such as 40% reduction in hallucinations, sub-500ms inference latency, and 60% latency improvements under load.

I partner with engineering and data teams to deliver reliable GenAI applications—document Q&A, summarization agents, voice assistants, recommender systems—and emphasize model governance, observability, and cost-efficient, multi-cloud deployments to turn ML research into production impact.
