Android, architecture and testing
We build tools for developers and share what we learn: a problem you will meet, what happens, and a clear way to check it.
A practical approach
The interesting part of building software often lives between the happy paths. We make tools, explore those edges, and explain what we find in a way you can put to use.
What we’re working on
Useful foundations, clear boundaries, and room to grow.
