Projects

Breathing — guided breathing

iOS · Android · Web

A one-tap calm app: a circle that breathes with you, guided by evidence-informed profiles and sound that breathes with you — including a real waterfall recording. No account, no ads, no data collection at all — the Android app doesn't even hold the internet permission. Built together with Claude (Anthropic). Free on the web at breathing.dev.

DiscoveryLab

In development

An educational app that makes complex knowledge accessible through interactive lessons. Three labs for different age groups — from playful discovery to deep systems thinking. No ads, no subscriptions, no manipulation.

Open Source

fsctl — a two-pane terminal file manager that asks the system instead of reimplementing it. Zero dependencies.
sshctl — show, check and safely rewrite ~/.ssh/config; proves a rewrite changes nothing by asking ssh -G.
homey-netwatch — watches your internet connection and reports how long it was gone, with UniFi gateway forensics.
homey-backupwatch — watches backup jobs and warns when one fails or stops reporting entirely.
homey-tvremote — a dashboard widget with a real remote-control layout for Android TV.
homey-wol — wakes network devices with a Wake-on-LAN magic packet, self-learning MAC address.
homey-novy — controls Novy Cloud / Pureline Pro extractor hoods over Bluetooth LE.
