About Me

I’m Nemanja Djurcic, a cyber security professional focused on cloud security, network defense, and resilient automation.

My work sits at the intersection of secure infrastructure, operational reliability, and hands-on defensive engineering. I care about making complex systems safer, faster, and easier to operate without creating unnecessary friction for the people using them.

Core Focus

  • Cloud security architecture
  • Security automation and operations
  • Infrastructure reliability
  • AI
  • Machine learning
  • Automation
