About Me

Hello all! I am Joseph Ziegler, a senior applications developer at Uber, based in San Francisco, California. I am working permanently remote from Roseburg, Oregon.

I'm an experienced IT professional with over ten years of working in the technical industry including experience in support, Linux administration, server automation, high availability, architecting and deploying large cross-region server environments for 30,000+ employees, CI/CD, configuration management, and TCP/IP networking. Experience supporting a large corporate-level infrastructure at a very fast-paced environment. I am able to support a large user-base, mostly under pressure, including campus-wide outages, working on several projects at once pertaining to services in the SRE and DevOps stack. Proven ability to drive projects on my own and having a positive impact on a company's infrastructure.

I am very interested in new technology, TCP/IP networking, system administration, automation, and Infrastructure as Code (IaC). I am ready to learn new things and to make a difference in the world with today's computer systems. My ambition is to utilize my diverse background and technical experience to make a positive impact on my future career and the world.

My passion is technology. Working in the technical industry is my dream and I do whatever I can to learn every single day and make a huge impact on the corporate infrastructure.
