What I'm looking for

I seek senior Data Scientist/ML Engineer roles where I can build production ML systems, lead teams, apply NLP and deep learning, implement cloud-native MLOps, and drive measurable business impact in collaborative, agile environments.

I am a Data Scientist and ML Engineer with 9+ years building predictive models, NLP solutions, deep learning systems, and data-driven analytics across healthcare, media and research domains. I specialize in turning complex, messy data into actionable insights and production-ready ML services.

I have designed end-to-end ML pipelines, deployed models at scale using cloud-native tools (AWS, Azure, GCP), and implemented MLOps practices with MLflow, DVC, Airflow and Kubernetes to shorten time-to-market and improve model reliability. My work includes fine-tuning transformer models, building recommender systems and applying advanced feature engineering and dimensionality reduction to improve performance.

I lead and mentor cross-functional teams, document model assumptions and KPIs, and collaborate with stakeholders to align analytics with business goals. I focus on clear communication, reproducibility, and measurable impact while continuously refining models through monitoring, A/B testing and root-cause analysis.
