Worked heavily at the intersection of our infrastructure and application code, often working both sides simultaneously to achieve desired results. Over the period my work saved Twitter at least $1M on AWS fees alone. Sole SRE and on-call 100% for duration. Handle all systems and often (rotation) application related production issues. Resolved challenging and critical system down/impairment situations. 100% remote work with occasional office visits.
