GNOME Linux desktop
I've significantly contributed to the GNOME Linux desktop and related technologies (active years: 2009-2020), mostly on text editors and other development tools (GTK applications and libraries).
My main interests were software architecture & development best-practices, re-usable code, API design and software product lines.
I have written this small book: The GLib/GTK Development Platform - A Getting Started Guide.
