Chris has been actively working with us in the Firefox data and stability world. He has been answering many data questions for people, providing guidance, building dashboard, extending & fixing the Firefox Telemetry implementation and mentoring contributors.
Chris has been working for quite some time on data-related Firefox stuff: from data-crunching, to analyses reviews and Telemetry client side development. Fun fact: he successfully tackles huge and nasty C++ Telemetry bugs at least once, per summer: both painful and fun, with high impact.
