About
🙋 Koen Poelhekke
Senior TypeScript Developer
Having worked with design agencies for over a decade, I know how to put a pixel on the right spot. With a strong eye for detail and good communicative skills I am able to create maintainable full-stack solutions from database to user interface.
I build full-stack applications end to end, designing APIs and data models on the backend and translating them into performant, accessible interfaces on the frontend. I’m comfortable in a Node.js/TypeScript or Kotlin/Spring Boot stack. As a certified Scrum Master I care as much about collaboration, priorities, coaching and improving the way we work as I do about architecture, technical quality, performance and maintainability.
Lately I have been building AI-driven features with OpenAI’s Responses API, developing an MCP server, and driving the adoption of Agentic Coding within our organisation.
