About Maruan

help engineering teams ship faster and more reliably — without burning down production.

With hands-on experience in Release Management on large-scale, mission-critical government IT programs and a proven background in SRE consulting, I bring both the operational depth and the strategic mindset to make your delivery pipelines more predictable, your incident response more resilient, and your engineering culture more reliability-first.

As an accredited PeopleCert ATO, I train and certify engineers in SRE Foundation and SRE Practitioner — bridging the gap between theory and real-world reliability engineering at scale.

What I can do for you:
•Release & change management for complex, regulated, high-availability IT environments
•SRE implementation: SLIs/SLOs/SLAs, error budgets, toil reduction, blameless postmortems, incident workflows
•Platform engineering & DevOps transformation: CI/CD pipelines, GitOps, infrastructure as code, observability stacks
•Reliability consulting for cloud-native, containerized, and microservices architectures (Kubernetes, Docker, Helm)
•AIOps & automation: reducing MTTR, improving MTTD, shift-left testing, chaos engineering
•FinOps-aware architecture: cost-efficient reliability at scale
•SRE Foundation & SRE Practitioner training (PeopleCert certified, accredited ATO)
