Oluwatosin Jegede - Platform, DevOps, SRE & MLOps Engineer

About Me

Platform Engineer | DevOps, SRE & MLOps Specialist | Problem Solver with a Systems Mindset

My journey into platform engineering began with a simple question: How can we build systems that not only run, but scale securely, enable developer productivity, and adapt under pressure?

Since then, I've spent the last few years helping startups, AI/ML companies, and enterprises answer that question by designing internal developer platforms, implementing comprehensive observability frameworks, and building secure MLOps pipelines across AWS, GCP, and hybrid environments. I've delivered self-service platforms, automated GitOps workflows, and resilient infrastructures, achieving outcomes like 30% cloud cost reduction, 40% faster deployment cycles, and sustained 99.99% uptime.

As a Platform, DevOps, SRE & MLOps Engineer with over 4 years of hands-on experience, I specialize in creating platforms that abstract complexity while providing powerful self-service capabilities. I excel at modernizing infrastructure using Kubernetes (EKS/GKE with Istio service mesh), advanced Terraform configurations, ArgoCD for GitOps, and implementing monitoring solutions with Grafana and Prometheus. My approach focuses on building platforms that are secure-by-design, observable-by-default, and enable teams to move fast without breaking things.

Platform Engineering Philosophy

I believe that great platforms are invisible to developers when they work, but powerful enough to enable innovation at scale. My approach centers on building internal platforms that abstract complexity while providing self-service capabilities, comprehensive observability, and robust security foundations.

Platform engineering isn't just about tools - it's about creating ecosystems that empower teams to move fast without breaking things. I focus on building platforms that are secure-by-design, observable-by-default, and scalable-from-day-one. Every architecture decision is made with developer experience, operational excellence, and business outcomes in mind.
