I’m applying for the Site Reliability Engineer position at PagerDuty. After spending the last few years building and maintaining high-availability distributed systems, I’m drawn to the opportunity to bring that experience to a company that’s shaping how the industry works.
At my current role, I designed an automated incident response pipeline that reduced MTTR from 45 minutes to 8 minutes across 200+ microservices. This wasn’t just a technical win — it changed how our team operates and directly impacted the business.
Beyond that, I built a capacity planning system that predicted scaling needs 2 weeks in advance, preventing 12 potential outages in the last quarter. These experiences taught me that the best work happens when technical execution meets clear thinking about what matters to users and the business.
I’d welcome the chance to discuss how my experience in reliability engineering and SLO management could contribute to your team. I’m available for a conversation anytime.
