On a mission to build the best Android browser.
An automatic vouch for being a Mozilla employee.
Sebastian is paid staff and part of the Firefox for Android core team.
I can vouch for Sebastian's build system chops (he landed Android 23 SDK support \o/) and his coding chops (he reviewed much of my Firefox Account on the web integration \o/).
Sebastian is part of the core Firefox for Android development team. He helps make Firefox for Android awesome!
Awesome Firefox for Android contributions!
