Summary
🤩
Rockstar🎓
Top SchoolAllan Fernandes is a Tech Lead and senior software engineer based in São Paulo with 8–10 years of experience designing and delivering cloud-native e-commerce and integration platforms. He’s led end-to-end migrations and real-time synchronization projects—replacing legacy iPaaS with custom Node.js/TypeScript services and Redpanda—to cut costs and boost reliability while mentoring mid-level engineers. Comfortable across backend (Node.js, PHP, Python), frontend (React, Vue), and cloud tooling (Kubernetes, AWS/GCloud/DigitalOcean), he blends architecture decisions with commercial outcomes, having driven launches for global brands and marketplace integrations. Pragmatic and curious, he champions engineering standards and automation (iPaaS, Celigo, n8n) to make systems more maintainable and business-aligned. An early game-developer background gives him a hands-on debugging edge and a knack for tackling low-level problems when needed.
