What I'm looking for

I’m looking for a team where I can build reliable GenAI (RAG + agents) and scalable AWS ML pipelines—focused on low latency, strong evaluation/guardrails, and production MLOps practices.

I build production-grade machine learning and Generative AI systems that actually ship: LLM-powered knowledge automation, retrieval-augmented generation (RAG), and agent workflows with structured outputs. At EPAM Systems, I designed and deployed Generative AI using guardrails and validation layers to improve reliability and reduce hallucinations, while also optimizing inference performance (about 25% latency reduction).

I’m equally focused on scalable data and reliable delivery—building data and ML pipelines on AWS, integrating model deployment workflows, and using distributed processing patterns. I also bring strong practical foundations from freelance work on credit risk and hybrid recommender systems, plus analytics experience using Tableau and PowerBI, and SQL-based big data engineering to support forecasting and analytics pipelines.
