Building and deploying production AI systems for engineering, manufacturing, and field service teams.
• Designed and built SELTALKS, a multimodal RAG assistant (Gemini + LangChain + FAISS) that helps engineers and customers diagnose issues across Selec's product line using text, code, or images — with an automated OCR pipeline that ingests wiring diagrams and tables straight from technical PDFs.
• Built an LLM-as-a-judge evaluation layer that scores every AI response against retrieved context in real time, plus a self-learning feedback loop that lets verified corrections be injected into the live system without redeployment.
• Built a debug copilot for our Grid Tie Inverter production line, combining structured SOP matching with semantic search, and a text-to-SQL assistant that lets operators query production/defect data in plain English.
• Developed an AI-based computer vision system for automated PCB wiring and solder inspection, using OpenCV (HSV color masking, contour detection, spatial analysis) to verify wire routing and origins, and a YOLOv8 model to detect and count solder joints/valleys across PCB images captured at multiple angles. Combined both into an automated Pass/Fail evaluation pipeline with a Tkinter GUI for visual fault indication — replacing manual visual inspection with a repeatable, automated check on the production line.
• Working across the full stack — model integration, retrieval, evaluation, reliability, and security — to get these systems trusted enough for daily production use.
