Useful before impressive
Every app starts with a specific problem someone actually has. Features follow from that problem, not from what's technically interesting to build.
Privacy explained clearly
Privacy isn't a badge. For every app I document what data is collected, what isn't, and why — in plain language, not legal boilerplate.
Ship, then improve
Apps get better through real use. Launching something focused and simple beats spending months perfecting something no one is using yet.
One builder.
Many useful apps.
ShirBuild is a one-person independent software studio based in Paris. I design, build, and ship apps across web and mobile — focusing on AI tools that are focused, private, and actually useful.
I started building publicly after years of working on larger platforms. The goal: a growing catalogue of small products, each solving one problem well.
