I built an end-to-end fraud detection system using LightGBM, with cost-based decisions, drift monitoring, and automated retraining. On an unseen month, it caught 78% of fraud and cut losses by 62%; its FastAPI service ran at 36ms p95.
I’ve also developed a grocery-delivery recommender that reached 7.5ms p95, and worked on ERP backend features at Reqpo.com, AI-enhanced automation at phaseup.ai, and reinforcement-learning robotics simulation at ACluster LLC. My projects span ML, recommendation and search, MLOps, and LLM applications.
