2021 – Now Fillter: personal request assistant for social media creators
Fillter is a form for all social media creator requests. they simply link Fillter in their link tree, Instagram bio, or website. Through a special questioning technique, the requests then come as usual via email – only in good.
The tool is a joint venture with Felix and Oğuz. We all work hands-on as equal cofounders, with our respective skills, to bring the project to the world.

I like to mentor and coach software engineers and first-time founders:
