About

I build digital products that connect software, automation and real-world workflows.

My main areas are React/TypeScript applications, PWAs, API integrations, automation, Linux/cloud environments and AI-assisted development. I care about solutions that are not only visually polished, but also understandable, maintainable and easy to ship.

Bridge the gap, create the world.

Engineering Principles

  • Ship useful software — solve the actual problem before adding complexity.
  • Prefer maintainability — readable code and predictable architecture beat clever hacks.
  • Design for the real device — responsive, accessible and fast UX matters.
  • Automate repetitive work — use tooling to reduce manual steps and errors.
  • Document what matters — setup, decisions and operational details should be discoverable.
  • Use AI as leverage — accelerate research and implementation while keeping engineering judgment in the loop.

Current Focus

  • Building and refining production-ready web applications and PWAs
  • Improving automation and API-driven workflows
  • Experimenting with AI-assisted development and developer tooling
  • Optimizing Linux, cloud and self-hosted environments
  • Growing FKDev as a technical portfolio and product-focused brand
