Infrastructure that holds up under scrutiny.

Six years of platform, security and application engineering for payments, DeFi and regulated financial workloads. AWS, Kubernetes, Terraform, GitOps and PCI-DSS-aligned architecture, and the web applications that run on them.

Full résumé
  1. a London-headquartered DeFi protocol

    Mar 2023 — present

    Senior DevSecOps/Cloud Engineer · London, UK — remote

    • Architected a production AWS EKS platform in Terraform supporting multi-environment workloads, with dynamic autoscaling through Karpenter and KEDA.
    • Rebuilt delivery around GitOps — Jenkins, GitHub Actions and ArgoCD orchestrating Helm releases. Median pipeline fell from 35 to 20 minutes, measured as ArgoCD sync plus Helm rollout across 90-day medians either side of the migration.
    • Automated multi-account provisioning with Terraform and Ansible, cutting environment setup from days to under an hour.
    • Ran to a 99.9% monthly availability SLO on successful request ratio at the edge, with an enforced error-budget policy: two consecutive breaching months froze feature rollout in favour of reliability work.
    • Designed a PCI-DSS-aligned architecture — IAM least privilege, Secrets Manager, VPC segmentation, Route 53, WAF, Security Hub, and centralised telemetry via AWS Security Lake with OpenSearch and Athena.
    • Built a unified observability platform on Prometheus, Grafana, Loki, Jaeger and Alertmanager with severity-routed alerting, cutting MTTR by 30%.

    I own the multi-account Terraform estate, EKS node lifecycle, the delivery pipeline and the security posture. I do not own application code or smart contracts.

    Senior DevSecOps/Cloud Engineer · Wuse 2, Abuja, Nigeria

    • Infrastructure provisioning, secure CI/CD, security posture and observability across four client platforms spanning retail, hospitality, e-commerce and cooperative finance.
    • One delivery standard across nine runtimes — AWS, Azure, GCP, Vercel, Render, Railway, Heroku, App Engine and Azure App Service — selected per client against operability after handover, compliance, cost at their scale, traffic shape and warmth requirements.
    • Built the Python services keeping Shopify, Odoo and Glovo consistent for a gifting retailer, including the idempotency, retry and reconciliation design that none of those platform APIs provide.

    I own infrastructure, delivery, security and observability, and built the Python integration services. Odoo functional configuration sits with the ERP team.
