Is your infrastructure keeping you up at night? Whether it's an unreliable deployment pipeline, a Kubernetes cluster you don't fully trust, or a cloud bill that keeps growing without explanation, I help engineering teams fix that. I've done this at serious scale, including for Microsoft and Banco Santander, as well as fintech startups, SaaS platforms, and digital agencies. 9 years across those environments means I've seen what breaks at scale, and I know how to build systems that don't. What I can do for you: - Design and implement SRE practices from scratch (SLIs/SLOs, error budgets, incident response) - Harden and scale Kubernetes (K8s) workloads on AWS, GCP, or Azure - Build CI/CD pipelines that development teams actually trust and use - Set up observability that tells you why something broke, not just that it broke (Prometheus, Grafana, Dynatrace, OpenTelemetry) - Eliminate operational toil through Infrastructure as Code and automation (Terraform, Ansible) Structured offerings with a defined outcome: - Cloud Cost Optimization Audit: I will review your AWS, GCP, or Azure spend, identify waste, rightsizing opportunities, and commitment gaps, then deliver a prioritized savings roadmap. Most clients recover my fee within the first month. - Multi-Tenant Architecture & Security Audit: I will assess your isolation model, RBAC, Kubernetes namespace strategy, network policies, cost allocation per tenant, and security guardrails, then deliver a gap analysis with concrete remediation steps. I hold a Certified Kubernetes Administrator (CKA) and Linux Foundation Certified Systems Administrator (LFCS) certification. I've worked across the full stack when needed so I understand what your developers are building, not just the infrastructure underneath it.
