01 Profile

AI/ML engineer who turns messy enterprise data into predictive systems and LLM products that move real business metrics.

I design end-to-end machine learning and generative-AI solutions — predictive analytics, deep learning, NLP, time-series forecasting, fraud detection, and RAG-based assistants — and carry them all the way to production with MLOps/LLMOps discipline. My work spans telecom, banking, and healthcare, where reliability, governance, and explainability are non-negotiable. I care about the unglamorous parts: clean pipelines, monitored models, and outcomes you can measure.
