Experimental works

Thoughtstack is a private, card-based playground for solo builders to capture ideas, track projects and document what they learn along the way.

I built it after accumulating bookmarks, prompts and notes across too many places, and wanted one simple space where everything would be easy to save, find, and return to.

Sprint0 helps first-time builders turn ideas into shipped products through a clear, structured journey.

I built it after attending meetups and hackathons where I kept seeing new builders struggle with the same questions: where to start, what to do next, and how to keep moving without getting overwhelmed.

Between Lines is a calm, private space for small book communities to read, reflect, and exchange thoughtful insights.

I built it after seeing how much enthusiasm there was for social reading across my circles, while the actual organization was scattered across event apps, group chats, and notes. I wanted one simple space that could bring it all together.

Aside turns favorite lyrics into a simple daily ritual, presenting one lyric each day in a calm, focused experience.

I built it as a distraction-free way to start the day with a little inspiration, before algorithms and endless scrolling take over.

B-side captures the small moments when music and lyrics linger, offering a quiet pause within the rhythm of the day.

I built it as an experiment in giving Aside a new visual identity while reusing the same backend and lyric API connection.

OOPlay is a visual, interactive playground for learning the fundamentals of object-oriented programming.

I built it while helping my son learn OOP and realizing there wasn’t a simple tool that struck the right balance between writing classes manually and being able to compile, run and test the results directly.

Help players grow every step of the way with structured feedback for handball athletes and trainers.

I built it after seeing how motivated my kids were to improve, while having no simple way to track feedback, understand their progress, and focus on what to work on next. I couldn’t find anything that really filled that gap.

Select a Füchse Berlin MD1 tournament and view the schedule, standings and live results.

I built it after seeing how manually tournaments are still managed, with schedules shared as PDFs, results tracked on paper and group standings calculated between games. It’s deliberately niche, focused on one team and the tournaments they attend, but it fills a very practical gap.
