Backend engineer with 13+ years of experience building production systems end-to-end, from database schema to Kubernetes cluster. Co-founded TipsterTrade, a sports betting tips marketplace that grew to 30,000+ users and R$10M+ GMV. Designed the platform from scratch. 15+ Go microservices, GraphQL and REST APIs, real-time messaging, payment processing, and a full observability stack, then led the technical transition through acquisition by Odds Scanner Group. Before that, spent 5 years as an independent contractor delivering systems across healthcare, smart cities, e-commerce, and data warehousing, which is where I moved from PHP to Go and never looked back. I care about simple systems that are easy to operate. I'd rather write a straightforward function than introduce a framework, and I'd rather fix the root cause than add a retry loop.
