Senior Data & AI Engineer · Solutions Architect — Belo Horizonte, Brazil · Remote (US time zones)

20+ years designing and delivering enterprise data platforms: data warehousing, data modeling, ETL, and analytics on the Microsoft stack. Currently the technical owner of BI and data architecture for a US financial services client. LLMs run through my daily development cycle, and a full-stack product background means I can own the whole path: schema, pipeline, and the application on top. Seeking senior IC and architecture roles: deep technical work, no people management.
