Lead Data Engineer | AI & Computer Vision | Team Leader | R&D
Lead Data Engineer with 8+ years and a Master’s in Computer Science from UFPE, currently leading a multi-squad R&D group at a top-5 Brazilian retailer. My work spans both sides of the data/AI boundary: dimensional warehouses, event-driven services and search platforms on one side, computer vision and LLM systems on the other, all running in production at retail scale. Adept at bridging technical and business needs, leading cross-functional teams in agile environments, and translating research into high-impact, production-ready systems.
