About Me

Hello! I'm Denis, a Senior Full-Stack Engineer based in Munich, Germany. I enjoy creating things that live on the internet, whether that be websites, applications, or anything in between.

With nearly 10 years of experience, I've had the privilege of building software for mobility startups, e-commerce platforms, and railway infrastructure monitoring — including real-time defect detection, asset lifecycle tracking, and smart alert management for critical rail networks.

My main focus these days is building accessible, inclusive products and digital experiences. I specialize in:

  • Cloud-native architectures
  • Microservices
  • AI/ML integrations
  • Technical Leadership
