🧠 About Me

I'm a full-stack developer and cloud engineer with ~5 years of software development experience. For the last 2+ years I've focused on backend and DevOps work. I build scalable systems, automate operations and design cloud-native security, turning complex requirements into actionable, auditable solutions. I have helped government and enterprise teams adopt Cloudflare DNS / WAF and automation workflows, and I work daily with CI/CD, IAM, monitoring, failover and DevSecOps practices.

Currently focused on

  • 🛡️ Application & cloud security: SAST pipelines, WAF governance, firmware analysis
  • 🦫 Backend systems in Go: APIs, RBAC, trading and funding bots
  • 👽 Quantum computing: IBM and AWS quantum learning paths
