Ayobami Adejumo

Senior Platform Engineer · FinOps Specialist · Cloudfrugal

I help Series A and B companies cut AWS bills by 30–50%, achieve SOC2 readiness, and build Internal Developer Platforms that scale without scaling the platform team.

freeCodeCamp FinOps Foundation CNCF


What I Build

AWS EKS Cost Optimisation  →  30–50% bill reduction, 60 days, fixed price
SOC2 Readiness Engineering →  Type 1 ready in 90 days, auditor-ready package
Internal Developer Platforms → Backstage + ArgoCD + Crossplane + Karpenter
FinOps Governance           → Unit economics, cost attribution, chargeback

Services — Cloudfrugal

I take 3–4 sprint engagements per quarter. Fixed scope. Fixed price. No custom quotes. No lengthy proposals.

Sprint What It Delivers Timeline
Infrastructure Cost Sprint AWS audit + 6 core optimisations + automation layer 60 days
SOC2 Readiness Sprint Engineering controls + evidence collection + auditor package 90 days
Platform Engineering Sprint Full IDP: Backstage, ArgoCD, Crossplane, Karpenter 90 days
Monthly Retainer Ongoing FinOps, cost reporting, platform evolution Rolling

Currently accepting clients for this quarter.
