What I'm looking for

I seek roles delivering production ML at scale with strong MLOps, model governance, and cross-functional collaboration in regulated or high-throughput environments.

I am an AI/ML Engineer with 4+ years of experience building production-grade machine learning systems for regulated financial services and industrial applications.

At Zest AI I designed scalable fraud detection pipelines processing over 1M daily transactions, improving precision and reducing false positives while cutting cloud and training costs significantly.

I specialize in MLOps, real-time deployment, and explainability—implementing CI/CD, drift detection, and RAG-based anomaly explainers to accelerate releases and reduce analyst investigation time.

I hold an M.S. in Data Science and bring hands-on expertise across PyTorch, XGBoost, Spark, AWS SageMaker, Kubernetes, LangChain, and model governance to deliver reliable, compliant AI solutions.
