# Alexandre Roux > I am Alexandre Roux, a software engineer (INSA Lyon, 1995) working as a freelance developer under the name Tekartik since 2009, based in the Gard, in the south of France. I build mobile, web and cloud applications in Flutter and Dart, with Firebase, and I publish as open source the building blocks I use every day. Born in 1972 in Valence, France, Alexandre Roux, a fan of pop, rock and folk culture, has played in a string of bands on guitar (Les Alchimistes, Mister Zog, Les Naufragés), then on bass (Barakatones, Coriandre), before venturing onto the double bass (Baptiste Pizon) and the accordion. A self-taught musician, he understood too late that lessons might have helped. Generated on 2026-10-25 from the about_me pack (facts in YAML, texts in Markdown).
