For when a browser is not enough: apps that sit in the tray, talk to the system, process audio or files locally and never send data anywhere. My open-source example is inkey, an offline Linux input engine that fixes text typed in the wrong keyboard layout, with a Rust core behind a C interface.

Tools that must work offline or keep data on the user's machine

Overlays, widgets and utilities for streamers and gamers

Audio and file processing that needs native speed

Interface. Electron or Tauri with React and TypeScript, with a design that matches your brand.

Native core. Rust or C where speed or system access matters, such as audio, input or file processing.

Packaging. Installers for Windows, macOS or Linux, and auto-update where needed.

Handover. The source code, build scripts and a short guide.

You send the idea, what it should do and the deadline

I reply the same day with questions or a plan and a fixed price

You test builds as I go, with updates every few days

I hand everything over and fix anything that comes up in the first two weeks

Code-signing certificates and store fees, which stay on your account.

Everything happens in writing, no calls needed. Send the task, the deadline and the budget, and I reply the same day.
