Made in Estonia

I work on practical NDA-free software to work with JavaCard and GlobalPlatform smart cards with Java, JavaScript, Android and on the web, publishing things under (L)GPL and MIT licenses.

GlobalPlatformPro and ant-javacard are among the most-used open source JavaCard developer utilities according to a study. JCardEngine is looking to become the most featureful open source JavaCard simulator for rapid development and testing.

Not too long ago GlobalPlatformPro received a small recognition from Google Open Source as a Peer Bonus!

Historically I’ve worked on software to make national eID cards like Estonian eID work on the web and on non-windows platforms, like writing Linux/macOS drivers for Estonian eID card and maintaining @OpenSC or creating @web-eid to ease user experience on the desktop.

Your sponsorship will allow me to do this more!
