I build distributed systems, and the platforms they run on.
Senior tech lead. I ship developer tools in the open, speak about distributed systems, and write about how these systems behave under load. 66 articles, 7 conference talks.
Products
Fitness tracker
A training and nutrition tracker for iOS, Android and the web from one codebase. Offline-first, and an MCP server lets an agent read and write the same data you do.
More in the works
A couple more products are still too deep in the build to show. They appear here once there is something to look at.
