What I'm looking for

I’m looking to lead SLO-driven reliability and observability—architecting self-healing Kubernetes platforms, automating incident response, and scaling blameless culture so reliability metrics directly improve product outcomes.

I’m a Principal Site Reliability Engineer with 10+ years of progressive experience building, operating, and scaling large-scale distributed systems from a DevOps foundation into deep reliability specialization. I focus on SLO/SLI/error budgets, automated incident management, and chaos engineering to keep systems resilient under real-world load.

I architect self-healing, cloud-native platforms on Kubernetes across AWS, Azure, GCP, and DigitalOcean, and I translate reliability metrics into business outcomes. I partner with C-suite stakeholders, define reliability OKRs, and build blameless engineering cultures through structured RCA and postmortems.

In recent roles, I’ve delivered multi-region active-passive reliability improvements, enterprise observability using OpenTelemetry/Prometheus/Grafana and distributed tracing, and predictive autoscaling with KEDA and HPA. I’m driven by proactive governance—reducing MTTR, improving root cause analysis speed, and identifying resilience gaps before they impact customers.
