About jauer

SRE working at the intersection of Network and Security infra at one of the FAANG.

Former SysAdmin at a small dialup/wireless/fiber/colo ISP in the US Midwest. Full stack where the stack went from datacenter power and cooling, fiber in the ground, to BGP, database perf tuning, and dev on backoffice/accounting/billing systems.
