At Preâmbulo Cloud, I led a multi-company billing migration that moved more than 1,500 subscriptions with zero billing incidents. I redesigned product ownership, invoicing, and payment routing, releasing the changes incrementally behind feature flags.
I integrated Brazil’s national NFS-e system, including automated issuance and product-specific tax rules. I also automated the Pipedrive-to-signed-contract flow, from creating client records to sending contracts for e-signature.
I built an AI assistant in the admin panel that streams answers based on internal documentation. I also developed a Python and Flask API to provision multi-tenant databases on Kubernetes and configure networking.
Previously, at Vendas Brasil, I built web systems to centralize client, partner, and quote data, along with a responsive PDF quote generator. I focus on tested, maintainable backend systems and have worked with PHP, Laravel, Python, and cloud infrastructure.
