Summary

Sr. UNIX System Administrator and DevOps
Aspiring FreeBSD Kernel Developer
Seeking a Design/Architect position embedded systems, storage, embedded appliances or technical leader in scale out of production operations

by David P. Discher December 12, 2018 19:47

I've had over a decade of experience working with FreeBSD in various different applications and use cases. I would prefer a position that would allow and support me to be involve with contributing back to the community and increasing my involvement in the FreeBSD Project. Outside of a role that has direct involvement with FreeBSD, my background lends to a position of leadership in the DevOps area, specifically around large scale operations for physical or cloud systems, storage, databases, or content delivery. Ideally, I wold prefer to work closely with all phases of a product or projects from the planning, design, implementation and execution.
