About Oladele

I help engineering teams ship faster and operate more reliably by building and improving their cloud platforms. I'm a Platform / DevOps Engineer specialising in Kubernetes, GitOps, and AWS — currently embedded in the platform team of a cloud-native fintech, where I build Kubernetes operators in Go with Kubebuilder, manage GitOps delivery via ArgoCD, and work across the observability stack on Prometheus, Grafana, and Loki.

How I can help:

Build and maintain Kubernetes operators (Kubebuilder, custom CRDs, reconciliation logic)
Set up GitOps-driven delivery pipelines on AWS EKS (ArgoCD, Argo Workflows, GitHub Actions)
Improve CI/CD, automated testing, and acceptance / health-check systems
Implement observability — Prometheus, Grafana, Loki, Slack alerting
Infrastructure as Code with AWS CDK (TypeScript) and platform engineering practices (Team Topologies)
What I bring:

Hands-on experience on a multi-environment AWS EKS platform managing 30+ infrastructure services (Kafka, ClickHouse, PostgreSQL, Temporal, ArgoCD) across dev, staging, and pre-production environments
Strict Test-Driven Development across operator code and CLI tooling
A Master's degree in Electronics & ICT Engineering (Cum Laude, KU Leuven, 2025), specialising in Software Engineering
Engagement model: B2B contracts only, via Simple Enough EURL (Belgian, EU citizen). Remote-first, available across European time zones.
