I'm Denis Zontak — 25+ years building enterprise systems, now shipping full web applications end-to-end. If you have a genuinely interesting problem to solve, let's talk.
I'm Denis Zontak, a senior software developer with 25+ years of experience building enterprise systems in Java, Spring Boot, and cloud infrastructure. These days I take a problem from idea to a deployed, production web application end-to-end — architecture, build, and ship — leaning on AI agents to move fast without cutting corners. Everything runs on Cloudflare's edge network for speed, reliability, and global scale. I take on a small number of projects that are genuinely interesting.
