Message

At Workify, I founded and engineer a fleet-maintenance platform with an AI repair assistant. I built a multimodal RAG backend that answers questions from service-manual PDFs using text and diagrams in English, Burmese, and Japanese, and shipped it in two products.

At Uber, I built Spark and Kafka pipelines processing 200M+ records daily and cut $290K a year in compute. I also co-built an iOS app at UC Berkeley Data Lab and earned second place at the Masumi Hackathon with Aeruku, an autonomous AI sales agent.
