Building tools for the developer community.
Where it started – my first Vic20
Why I Build What I Build
Many teams try to force standard tools into problems that are anything but standard. It works for a while, until the system needs to be reliable, explainable, and ready for real users.
I work with founders and leaders who are building ambitious products and facing "there is no template for this" kind of challenges. People who value clarity, long-term thinking, and honest conversations about trade-offs.
I listen first, then design the smallest system that can carry the whole vision. Clear boundaries, simple mental models, and AI where it truly adds leverage—not just because it is fashionable.
Less noise, more signal. Systems that stay understandable as they grow. Work that makes the next step easier, not harder, for the people who come after us.
