What I'm looking for

I seek roles where I can lead production-grade AI/ML systems, mentor teams, and deliver measurable product impact in a collaborative, product-driven environment with strong MLOps and scalability focus.

I am a Lead Data Scientist with over six years of experience building and deploying scalable AI/ML solutions across NLP, recommendation systems, computer vision, and MLOps. I translate complex product problems into data-driven solutions using cutting-edge technologies such as LLMs, PyTorch, Neo4j, MLflow, and Azure OpenAI.

I have a proven track record of improving model performance and driving product adoption — examples include architecting a Neo4j-powered personalized recommender that increased user acceptance rate by 80% and deploying production-grade RAG chatbots and LLM guardrails to enhance security and engagement. I have led cross-functional teams to migrate legacy data platforms and significantly reduce processing times.

I take an engineering-first approach to MLOps and productionization, delivering end-to-end systems from data pipelines and drift detection engines to model retraining and monitoring. I prioritize measurable business impact, operational reliability, and continual improvement of models in production.
