What I'm looking for

I'm looking to build practical AI and automation systems that integrate with real business workflows, while partnering closely with non-technical teams through discovery, expectation management, and training.

I turn AI into daily workflows for editorial, healthcare, and data operations teams. My multi-agent book-collation program reduced a 6–10 week manual process to under 90 minutes and cut literary translation from 2–5 months to 2–5 hours with humans in the loop.

At Asi Company Tecnologia, I build AI agents and scalable ETL/ELT pipelines for classification, semantic normalization, enrichment, and data migration. Across 20+ years in software engineering, I’ve modernized systems for Healthequity, led backend teams at modalmais, and delivered .NET, cloud, and distributed systems across fintech, healthcare, and public-sector organizations.
