👋 Hey, I'm Denys — Backend & AI Systems Engineer

Building fast cloud apps, automated workflows, and AI-powered solutions that actually ship.

I'm a principal-level engineer blending backend architecture, AI automation, and cloud-native engineering. I help teams turn messy systems into clean, scalable, and resilient platforms — and automate everything that slows development down.

⚡️ What I Do

  • AI Engineering — agents, RAG, automation workflows, task orchestration
  • Backend Architecture — Node.js, Python, microservices, API design
  • Cloud & DevOps — AWS, Kubernetes, CI/CD, IaC, observability
  • System Modernization — performance, reliability, DX improvements
  • Consulting (Prema Vision LLC) — helping companies ship faster & smarter
