Infrastructure that holds up under scrutiny.
I secure payment, DeFi and regulated-finance platforms across AWS, Kubernetes, GitOps and PCI-DSS-aligned architecture.
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.

A multi-account AWS organisation, built security-first
Hierarchical OUs, a centralised security account, production-grade SCPs with root-account protection, and Security Lake telemetry in OCSF — provisioned end to end in Terraform.

GitOps delivery for a payments-critical platform
Rebuilding release engineering around ArgoCD and Helm so that rolling, blue-green and canary deploys became routine rather than events.
- Median pipeline 35 → 20 minutes, measured as ArgoCD sync plus Helm rollout, 90-day medians either side
Zenith Chain · Abuja · 2020–2021
Running blockchain infrastructure at 99.99%
Nodes, wallet services and indexers on Kubernetes across 20+ microservices, with event-driven autoscaling absorbing high-throughput transaction spikes without degrading response times, and reusable Terraform modules behind every environment.
- 99.99% uptime across blockchain nodes, wallet services and indexers — high-availability configuration and automated failover, on checks that measure consensus progress rather than process health

Senior DevSecOps Engineer
a London-headquartered DeFi protocol
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.
- 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%.

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