I built AI platforms for D2C customer support, live code review, and research automation using Python, FastAPI, LangGraph, retrieval systems, and knowledge graphs. My AI Customer Support Agent System delivered 2â4s end-to-end latency, improved R@1 from 25.6% to 66.7%, and added safeguards for PII, prompt injection, hallucinations, and sensitive actions.
With CodeTurtle, I shipped a local AI code-review platform for GitHub repositories and live pull requests, indexing 2.5Kâ3.7K+ files and mapping 350+ dependency edges in Neo4j. I also developed Helix Research, an automated research pipeline that reduced collection-query latency from approximately 40 seconds to 4 seconds through retrieval, caching, model routing, and evidence consistency checks.
