I've built production systems at Spaay, Grupo Bringel Oficial, and IB Investimentos, spanning backend APIs, automation, frontend interfaces, databases, and deployment.

At Spaay, I developed more than five Python and Playwright RPA workflows, cutting manual execution time by approximately 30%. I also automated REST API, webhook, and scheduled-job workflows that reduced repetitive operational steps by approximately 40% and optimized backend processes and queries by up to 20%.

At Grupo Bringel Oficial, I worked end-to-end on SISUMS, from requirements and relational modeling to Django REST APIs, Angular interfaces, integrations, testing, and production deployment. I built SISREG processing workflows for more than 1,300 records and automated communications through Meta API and webhooks.

As a technical lead and full-stack developer for IB Investimentos, I designed and delivered a financial ERP for an investment portfolio of approximately R$2 million. I implemented contracts, installments, payments, and administration workflows while integrating Evolution API instances that automate more than 5,000 messages each month.
