I build the
useful stuff.

Software, systems, and strange little ideas — made real. Twenty-five-plus years turning complicated problems into tools people can actually use.

01 / Philosophy

Good technology should feel obvious when it reaches the person using it.

I work across the whole stack—from databases and pipelines to product interfaces and native Mac apps. The through-line is pragmatic craft: understand the real problem, remove the noise, and ship something durable.

02 / Work

Three hats.
One builder.

03 / Independent builds

The Gnome
workshop.

I ship focused developer tools for problems the giant platforms make too complicated. Native where it matters. Small on purpose.
