What can I do for you?

During my career in software I have build up a holistic skillset from building complex frontend web components to building robust and scalable microservice applications.

Most cruicial is my ability to set foot into any project within days, boost development with years of experience in companies different shapes and sizes and bring everybody along for the ride. My goal is to reignite team spirit, deliver your project on schedule and show the way to manage the problem to build a maintainable software product.

Agility is king. Working my way into software development from a science background I always keep the non-technical part in mind that makes some software great and why some products fail. It's this T-shape allround experience, technical excellence and my optimistic motivation that I can bring into your team to get it done.
