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.

Latest from Lab

Fresh notes from the bench: scripts, rebuild logs, Linux tweaks, networking experiments, and technical writeups that are still alive enough to change tomorrow.

Selected Projects

The stable layer of the site: projects I can stand behind without caveats. These are the systems, tools, and paid work summaries that best represent how I build, debug, and structure real-world software.
