Hey there 👋 I'm Angelo 🇵🇭

Product-Focused Backend Engineer • SaaS Development • Real-Time & Event-Driven Systems • Occasional debugger of production fires 🔥

WakaTime

Badge of Honor

🧠 What I do

I build backend systems that power SaaS products — especially features that need to stay reliable under real-world usage.

My focus is on:

  • SaaS backend development (APIs, product features, integrations)
  • real-time systems (WebSockets, messaging, live updates)
  • async processing & background workflows
  • handling concurrency and data consistency in production systems
  • building systems that break gracefully instead of catastrophically

I care less about “perfect architecture” and more about systems that work reliably in production when things get messy.

🧩 What I care about

Product engineering · System Design · Scalability · Reliability · Clean architecture (when possible)
