Hey there! I’m a software developer and system administrator, currently working as a Production Engineer/SRE at Facebook. I work as part of the Web Foundation team, responsible for the overall performance and reliability of Facebook’s user-facing products. I concieve, design, and improve systems that make Facebook more performant, scalable, and reliable.
