What I'm looking for

I'm looking to build and ship production AI systems, especially RAG, agentic workflows, and applied ML products, while growing in TypeScript and React.

I've built VERITAS, a multi-agent RAG copilot for auditable analysis of SEC filings, combining hybrid retrieval, cited claims, and a 94% retrieval hit rate.

My projects apply AI to practical industrial problems: Circuit Guard Pro reduced manual asset-inspection time by 80% using YOLO, while an XGBoost/LightGBM energy-loss prediction solution placed top 2% among 1,500+ teams in the Zelestra × AWS ML Ascend Challenge.

At Apptad, I built a multilingual OCR and translation pipeline with FastAPI, EasyOCR, and Llama 3.2. I enjoy shipping reliable AI services with FastAPI, Docker, CI/CD, evaluation harnesses, guardrails, and human-in-the-loop controls.
