Rockstar🎓
Top SchoolGuilherme Castello is a pragmatic software developer based in São Paulo with a track record of delivering integrations and scalable services across ERP and CMMS domains. Over the last six years he has evolved from electronics and maintenance roles into full-stack engineering, bringing a systems-minded approach to API design, microservices, and migrations from legacy platforms. At TRACTIAN he leads integration projects using Python, Typescript, Go, Kafka and Clean Architecture, while prior roles delivered React/Next.js front-ends and Java/Spring backend systems for large-scale ERP deployments. He’s comfortable owning end-to-end solutions—from designing integration strategies to implementing Dockerized services and Redis-backed pipelines—and has real-world experience handling SOAP and public invoicing systems unique to Brazil. Guilherme’s interdisciplinary background (electronics technician to systems analyst) gives him a practical edge when balancing operational constraints with clean software design. Always focused on pragmatic results, he thrives on turning complex business processes into reliable, maintainable systems.
