Websites and apps that do one thing properly.

Websites, browser extensions, and Android apps — designed, built, and deployed by the same person. You explain it once.

Selected work

Three projects, three platforms, all of them running.

Landing page + admin

Csendes Tér

A small practice takes applications for its group sessions without touching a spreadsheet. Places are capped automatically, confirmations send themselves, and the owner edits events from a private page instead of asking anyone for help.

The public page renders whichever session is currently active — nothing about a specific cohort is hardcoded, so a new date is a form field rather than a code change. Applications, capacity and confirmation emails are handled on the server, with the owner's own view behind Google sign-in.

Browser extension + self-hosted server

Downloader Plugin

Save a video, an audio track, a trimmed clip, or a short playlist from the page you're on — with the actual work happening on a machine you own rather than someone else's service.

Downloader Plugin for Android

The same tool from a phone: share a link into the app and the file lands in your normal Downloads folder, with progress in the notification shade like any other download.

Containerized Gradle build
