Results-driven Site Reliability Engineer optimizing distributed, mission-critical systems for reliability and scalable performance.
What I'm looking for
I’m a results-driven Site Reliability Engineer with over 15 years of experience driving transformation across infrastructure systems with diverse complexities. I’ve spent years designing and optimizing distributed, mission-critical systems, with a strong focus on operational reliability, cost savings, scalability, and performance.
In my current role at Ocado (Barcelona), I lead automation efforts to reduce deployment pipeline job running times by reusing artefacts and minimizing resource consumption on runners—improving reliability and reducing support burden from failing jobs. I’ve also saved millions by reducing Kinesis event stream volume and migrating to shared load balancers, while unifying the monitoring stack and improving visibility for over 2400 engineers.
I build for durability through proactive monitoring and operational rigor. I’ve pioneered SLO/SLI practices to strengthen observability across the operational plane, transformed logging using OpenSearch (and Grafana Loki in some production environments), and built and led the incident response framework—supporting reduced MTTRs and transparent mitigation with a consistent retrospective process.
Previously, as a Senior Site Reliability Engineer at Ocubicle/Swoom (Dallas), I engineered high-performance SLOs and SLIs for mission-critical systems, led a transition to a robust automated Kubernetes deployment architecture, and helped implement secure CI/CD workflows in GitHub Actions across multiple cloud providers. I also bring domain breadth across finance, identity, edtech and e-commerce—working across AI, blockchain and devops—alongside leadership experience in cross-functional environments.
