Our Staff

Mozilla Messaging has a handful of staffers, who work with a much larger global community of contributors.

David Ascher, CEO

David has overall responsibility for the company's operations, strategic direction, and outreach. As such, he spends much of his time in product design discussions and community building activities.

David's current priorities are to help define the product roadmap for Thunderbird 3, and to continue to enroll both individual and corporate community partners.

Rick Tessner, Build Engineer

Rick is half-developer, half-configuration manager, all about automation. His background includes a variety of automation tasks, and experience deploying and customizing some of the same tools that the Mozilla project uses on a daily basis, as well as providing leadership in identifying improvements in build and configuration systems for diverse projects.

Rick's top priority is to learn about the existing Thunderbird build systems, working in collaboration with the existing Build team, so that we can reach best-of-breed engineering practices, notably in build automation, test automation, performance monitoring, and reporting.
