About

Marcelo Santos

Data Scientist & Applied AI Developer · Brazil · Remote

I'm Marcelo Santos, founder of MJS Planejamento e Projetos. I work at the intersection of data science, applied AI and process automation — always focused on solving real business problems.

Over the past years I designed and shipped to production systems that integrate construction-industry ERPs (UAU, TOTVS RM), automate sales, receivables and legal operations, and apply semantic search and autonomous agents over corporate data.

My edge is combining domain expertise (construction, ERP, finance) with solid software engineering: resilient pipelines, Docker Swarm deployments, and AI that actually reaches production — not just the notebook.
