Secure development · sysadmin → security → dev
Software that's hard to break — built by one senior engineer.
I'm Blago. For 15+ years I've built, secured, and monitored systems end to end. You work directly with me — from the first call to production. No agency, no handoffs.
You talk to me. No account managers, no handoffs, no junior devs learning on your budget.
I don't bolt security on at the end. It lives in the architecture from the first commit.
15+ years across sysadmin, security, and development — one person sees the whole system.

About
Hi, I'm Blago Culjak.
I started in system administration — keeping infrastructure reliable, scalable and secure. That grew into security: penetration testing, intrusion detection, threat prevention. Then development, where it all comes together into apps that are fast, correct and genuinely hard to break.
