Developer and partner at, a humble studio for strategy, design and code.

Hi, I’m Harry and I’ve worked with the internet for more than 15 years, most often as a developer, but also copywriter, project manager, scrum master and product owner. To this day I’m enthusiastic about the possibilities opened up by technology and design, while also retaining a healthy skepticism about this strange new world we live in. Or maybe I’m just getting old and cranky … “Alexa, play some uplifting music" … yeah, that’s better. Now where were we?

Right. In 2015 I co-founded, a studio where we team up with clients to solve their digital challenges, starting with a sound strategy, translating it into appropriate interfaces and building the resulting digital products. In my work at diesdas, I currently focus on democracy tech, trying to make the world a tiny bit more humble, sustainable and inclusive. Equally important to me is creating a modern and diverse work environment in which each person can be themself, where we can laugh together and do meaningful work. We currently have a team of ~25 wonderful people, among them developers, strategists, designers and project managers from all over the world. Let’s work together maybe?

If you want to know more, you can find some of my writing on our company blog and get an impression of our inner workings through our employee handbook. Our social channels on Twitter, Instagram and Tumblr are also worth a look.

In the past I studied computer science + media, worked at 11 Freunde → Edenspiekermann → A Color Bright, taught students at HTW Berlin about web development and gained quite a bit of experience in public speaking. I’m always happy about speaking opportunities at meetups/conferences or interview requests.

Thanks for stopping by; live long and prosper! 🖖
