Hey. I’m Bangie – engineer, builder, and digital mechanic.

Designing efficient infrastructure, fixing messy codebases, and mentoring devs from Niš to the cloud.

Backend Architect

From monoliths to microservices, I design systems that are reliable, secure, and maintainable — even when no one reads the docs.

Dev Mentor

I help teams level up by simplifying complexity, guiding young devs, and building things people actually understand.

Infra & DevOps

Proxmox, WireGuard, Caddy, CI/CD pipelines — I automate, self-host, and keep things running without drama.

Zero-Trust Mindset

Everything encrypted, nothing assumed. I build with security in mind — not as an afterthought.

Selected Work

A curated selection of things I’ve built — some for clients, some for myself, all handcrafted and battle-tested. From full-on systems to critical refactors, each project reflects my zero-bullshit, backend-first philosophy: clean architecture, resilient infrastructure, and just enough overengineering to make it future-proof.

Mentions

Some people noticed my work. I noticed their servers stopped going down. Win-win.
