What I'm looking for

I seek roles building production NLP/ML systems where I can lead model development, optimize inference, and drive measurable business impact in collaborative, product-focused teams.

I am a seasoned Machine Learning Engineer with 10+ years of experience in NLP and data science, skilled at designing, developing, and deploying end-to-end machine learning solutions that drive measurable business impact. I specialize in large-scale data processing, model optimization, and enterprise AI systems, translating complex business challenges into scalable AI-driven solutions.

My recent work includes building RAG-based question-answering systems on Azure, developing PDF segmentation, NER and relation-extraction pipelines, feedback-validation services, and high-accuracy document classification services. I emphasize production-ready deployment (FastAPI/Flask, Docker, Kubernetes), model optimization (quantization, distillation), and cross-team collaboration to improve operational efficiency and decision-making.
