Work

For more than ten years I have built software for clients across a range of industries. On top of that, I build two products of my own.

Products

My own products. Built in my free time, because I enjoy it. Idea, design and code are mine.

Idea, design and code are mine.estimarloWeb · livePlanning poker for sprint planning. Free and no signup, the voting runs in real time. Built with the stack I like: Java, Spring Boot, Angular.
