About me

Two decades of turning ideas into reliable products.

I started coding in the early 2000s and have grown alongside the industry — from hand-written websites to cloud-native platforms and cross-platform mobile apps. Over 18 years I've led teams, architected systems and delivered products used by thousands of people.

I care about clean architecture, performance, accessibility and a great user experience. Whether it's a quick MVP or a complex enterprise platform, I focus on solutions that are simple to maintain and ready to scale.

  • Full-stack development & system architecture
  • Team leadership & mentoring
  • Agile delivery from idea to production
