Senior Full-Stack Engineer & Software Architect

Software that holds up in production.

I build and run systems end to end – from API architecture to frontend, apps and infrastructure. And I help teams bring AI agents into their development safely and effectively.

Available from 10/2026 · 5 days/week · Remote, on-site by arrangement

Full-stack engineer with more than 19 years of experience – from Head of IT to founding my own platform. I build and run systems end to end: microservice backends in Kotlin and Java, web frontends in Angular and React, native apps and the infrastructure underneath. My focus is clean API architecture, cloud migrations, CI/CD and observability – and increasingly AI-assisted software development with agentic workflows.
