What I'm looking for

I seek roles building production ML/LLM systems with emphasis on RAG, evaluation/monitoring, cost optimization, and scalable pipelines in collaborative teams.

I am an AI/ML engineer with hands-on experience developing and evaluating LLM-driven systems in production, focused on RAG evaluation, automated benchmarking, anomaly detection, and scalable ML pipelines. I have built automated evaluation frameworks, internal agent evaluation tools, and optimized batch processing and APIs to reduce costs and improve reliability.

My background includes end-to-end ML system development, computer vision projects using YOLO and OpenCV, and production-facing services using Flask and FastAPI. I deliver measurable impact—such as reducing evaluation and data retrieval workflow costs by over 40% and achieving 92% accuracy on CV detection tasks—while emphasizing robust monitoring, regression detection, and reproducible benchmarking.
