Software Engineer
Software engineer and full stack developer with over thirty years of experience building, maintaining, and improving software. Strong at bringing structure, understanding existing systems, and developing practical web applications. Works with TypeScript, React, Next.js, C#, databases and AI tools such as Claude Code and ChatGPT. Available for sustainable part-time work.
Motivation
With my background as a software engineer and full stack developer, I am looking for a role where I can apply my broad experience in a focused way. I have over thirty years of experience designing, building and improving software — from business-critical web applications and customer portals to modern full stack applications with TypeScript, React, Next.js, C# and databases.
What defines me is that I quickly bring structure to complex systems. I enjoy making existing software more understandable, stable and usable, but also building new tools that deliver direct value. Lately I have been working a lot with AI tools such as Claude Code and ChatGPT, including in my own projects such as Scrum4Me and the Inspannings Monitor. This allows me to combine years of technical experience with a modern, practical approach to development.
I prefer a part-time role where I can contribute in a sustainable and focused way, at approximately 50% capacity. This is where I perform best: with clear priorities, clear communication and work where quality, continuity and reliability matter.
I bring calm, experience and technical overview, and enjoy working with people who want to build software that is actually used.
