At GlobalLogic, I build production LLM agents and workflows for Hitachi, including a financial report validation system that reconciles figures across four Excel reports and traces discrepancies to their source. My AI workflows have cut document verification time by about 90%.
I also designed a Linux-based workflow that runs the client's original VBA macros in an on-demand Windows and Excel runtime on AWS EC2, avoiding about $2,600 per year in licensing per bot. I present solution designs, results, and next steps directly to Japanese Hitachi stakeholders in English.
As a freelance data scientist and AI/ML engineer, I delivered data science, machine learning, and automation projects for clients. One project forecast volatility-index and ETF direction using cross-asset features and walk-forward evaluation.
In a freelance BTC trading project, I combined PPO, A2C, and TD3 with a deterministic risk engine; on a held-out 372-day test, it achieved 15.82% alpha versus Buy & Hold and reduced maximum drawdown from 47.86% to 19.90%. I also combined YOLO object detection with a PPO policy for an autonomous drone, testing it first in simulation and then on a physical drone.
