Winston Karanja

I'm building analytics-grade AI workflows over enterprise data, including an Oracle NL2SQL agent for KPLC that turns executive questions into SQL across sales, finance, operations, and customer warehouse domains.

At Computech Limited, I also built BidBuddy, an internal tender-to-submission platform spanning six procurement portals and a sequential CRO-to-CGO approval process. I delivered digital service forms with role-based access, live e-signatures, reporting, and CSV export.

At LSL, I built a context-aware LangChain chatbot with persistent history, memory, conversation forking, and tool calling. I've also implemented FastMCP automations, Celery and Amazon SQS async pipelines, and Pinecone-powered RAG search.

My work includes fraud and anomaly detection workflows for on-chain data, a KCAA flight-log pipeline that cut billing backlog by 30%, and computer-vision models such as a YOLO pest detector with 94% precision across 102 classes.
