Summary
👤
Senior🎓
Top SchoolRafael Barreto is a backend developer with 8 years of web and cloud engineering experience and full EU work rights, currently based in Toronto. He designs and implements scalable, privacy-conscious backends for healthcare and startup platforms using Node.js/TypeScript, PostgreSQL/MongoDB, Redis, Docker, and AWS, and is experienced with Medstack, Stripe, and CI/CD-driven Agile delivery. His earlier career as an SAP Basis/DBA gave him deep operational expertise—performance tuning, migration strategies and automation—that he brings to modern distributed systems. Rafael frequently partners with product owners to translate requirements into prioritized backlog items and robust APIs, and has built microservices, auth systems (OAuth2/JWT), and telemedicine data flows in production. Comfortable across the full backend lifecycle, he blends enterprise-grade reliability with startup velocity and a practical focus on data protection and performance. An uncommon strength is his cross-era perspective: decades of systems administration through contemporary cloud-native practices.
