By day, I'm a Backend Java Developer, by night, I mostly build keyboard-first, desktop software and occasionally write about it.

Projects

Editora Active
A keyboard-driven, cross-platform programmer's editor with IDE capabilities that stay out of the way until you need them.
Termina Active
A cross-platform terminal emulator built on JavaFX, running a real shell on a real pseudo-terminal and rendering the emulated screen to a canvas.
Insula Active
A keyboard-first desktop reader for ZIM offline archives — Wikipedia and hundreds more, downloaded once and read forever with no network.
Modula Active
A broadcast radio receiver for RTL-SDR dongles. Commercial AM and FM, in stereo, with RDS — a radio, not an SDR panel.
Nux Active
A desktop client for Network UPS Tools — live UPS dashboard, history, and power-event notifications, speaking the NUT protocol directly with no drivers.
Capsula Active
A terminal UI for safely managing SSH configuration — browse, edit, connect, and check reachability without rewriting the parts you did not touch.
Calcula Active
A keyboard-driven, Symja-powered symbolic calculator in the spirit of Emacs Calc — a native JavaFX interface for algebra, calculus, typeset mathematics, and interactive plots.
