What I'm looking for

I'm looking for a remote independent-contractor role where I can build and evolve scalable backend services, event-driven integrations, and enterprise platforms across architecture, delivery, observability, and production support.

I've designed and delivered an end-to-end fiscal document processing platform, from architecture through production support, processing approximately 1 million NFCOM documents per billing cycle in around six hours with C#/.NET, Apache Kafka, PostgreSQL, and MongoDB.

Across more than 20 years in enterprise software, I've built REST APIs, integrations, automated delivery pipelines, and resilient event-driven workflows. I also supported and evolved TOTVS Protheus for approximately nine years, translating industrial, commercial, and administrative needs into AdvPL customizations and enterprise integrations.
