I build and maintain applications that simply work — reliably, quietly, and with a human touch.
03:00 — backups complete · monitoring OK · you sleep, your apps keep running
I build custom applications — from web systems to mobile apps. Fast, secure and maintainable.
Updates, monitoring, bug fixes. Your application keeps running even while you rest.
Linux servers, backups, security. Stable operations with (almost) zero downtime.
Architecture, development efficiency, process improvement — in plain language, no buzzwords.
~/apps
I don't just build for clients. I run my own apps that solve real problems — calmly and without chaos.
in production
Calm record-keeping for housing association committees. Apartments, residents, documents and a history of changes in one place — without the chaos of spreadsheets and e-mails.
Your terminals, finally in order. Project-based workspace, session restore and live git status. Free on GitHub.
One tap and your people know you're OK. Coming soon to the App Store and Google Play.
coming soon
Offline-first logbook for SOTA, GMA, WWFF and POTA activations. One line, one Return, one logged QSO — exported to clean ADIF.
~/about
My name is Petr Hložek and I have been developing applications and managing servers for more than 20 years. I founded Calmbit because I believe technology can be reliable, calm and human at the same time.
You talk directly to the person who understands your project and looks after it personally — from design to day-to-day operations.
