What I'm looking for

I’m looking to drive reliability and incident response for mission-critical systems, deepen observability with SLI/SLOs, and build AI-driven automation that enables predictive scaling and self-healing in cloud-native Kubernetes environments.

I’m a Senior DevOps & Site Reliability Engineer focused on enterprise-grade high availability, distributed systems, and cloud-native automation. I lead Incident Command for critical Sev-1 operations, triaging code, network, and multi-cluster configuration issues to reduce MTTR and protect uptime.

I architect observability maturity with Prometheus, OpenTelemetry, and Grafana—defining production SLI/SLO dashboards and automated alert burn-rate strategies to catch anomalies before they impact downstream business. I also build and scale automation platforms on Jenkins, GitLab CI, and ArgoCD, turning complex operational workflows into reliable, repeatable systems.

Over the last 2 years, I’ve delivered AI-driven ops by integrating Python and Bash automation with AI tools to orchestrate self-healing tasks, manage configuration states, and implement proactive infrastructural changes. Across AWS multi-region Kubernetes and broader AWS services, I’ve improved reliability, security compliance, and cost efficiency through Infrastructure-as-Code and rigorous CI/CD guardrails.
