Hi 👋, I'm Barbu Bujor

Backend Engineer • Distributed Systems • Integration & Middleware

🧠 About Me

Backend Engineer with a strong focus on reliable, deterministic systems and legacy modernization.

I design and build backend services that sit between high-performance hardware, legacy systems, and modern UIs, with an emphasis on:

• Safety & risk reduction
• Clear boundaries and clean architecture
• Event-driven and real-time systems
• Long-lived systems that must not fail silently

While I have experience with AI/ML, my core identity is backend & systems engineering, especially in environments where “move fast and break things” is not acceptable.

🏗 What I Work On

• 🛰 Integration & Middleware Systems

  • Wrapping legacy C/C++ monoliths with clean APIs (Anti-Corruption Layers)
  • Designing backend services that isolate risk and complexity

• ⚡ Real-Time & Event-Driven Backends

  • Data ingestion, filtering, caching, and fan-out
  • Redis, WebSockets, Kafka-style architectures

• 🔌 Backend APIs & Services

  • FastAPI / REST APIs
  • Clear domain boundaries (Clean Architecture)
  • Deterministic behavior & testability

• 🧱 Platform Foundations

  • Dockerized services
  • CI/CD with GitHub Actions
  • Cloud-ready (AWS / Azure / DigitalOcean)
