DevOps & Cloud Engineer  ·  Ibadan, Nigeria

I build infrastructure that ships fast, stays observable, and does not break at 2am. From Terraform provisioning to Kubernetes orchestration, I work across the full deployment lifecycle with a methodical precision borrowed from years of clinical training.

What I do

Is your cloud infrastructure slowing your team down instead of moving it forward?

I help engineering teams and startups build reliable, automated AWS infrastructure so deployments are fast, repeatable, and stress-free. Whether that means setting up a CI/CD pipeline, provisioning a full cloud environment with Terraform, or getting your Docker and Kubernetes workloads running properly on AWS EKS: I handle it end to end.

Here is what that looks like in practice
85s
Git push to live production
  • Maven build
  • SonarCloud quality gate
  • Nexus artifact publish
  • CodeDeploy blue/green across 2 EC2 instances

  • Multi-AZ RDS architecture
  • ~60 seconds average recovery time
  • Zero application disruption
Here is what I can do for you
AWS Infrastructure Design
EC2, RDS, S3, Auto Scaling, ALB, VPC, IAM, CloudWatch, designed for production from day one.
CI/CD Pipeline Setup
GitHub Actions + CodeDeploy. Commit to production in under 2 minutes, every time.
Infrastructure as Code
Full Terraform with modules and remote state. No manual console clicks, ever.
Container Orchestration
Docker, Kubernetes, AWS EKS. Service discovery, auto-scaling, the works.
Monitoring & Logging
Prometheus, Grafana, Node Exporter, CloudWatch. Stop finding out about problems from your users.
Linux Server Management
Nginx reverse proxy, SSL/TLS, proper secret management. Secure by default.

I document everything. When the engagement ends, your team can maintain and extend the infrastructure without needing me on call.

Experience

DevOps Engineer
Apr 2026
Sabiguy Service Marketplace  ·  Terraform · Docker · GitHub Actions · AWS EC2 · ECR · API Gateway
Infrastructure & CI/CD
  • Provisioned 26 AWS resources via Terraform (VPC, EC2, ECR, API Gateway, CloudWatch) with S3 remote state; migrated backend from Render to AWS with zero downtime.
  • Built a 3-job GitHub Actions pipeline (build → staging → production) with commit SHA image tagging and manual approval gate; end-to-end deployment in under 3 minutes on every push.
Security & Cost
  • Enforced branch protection with required PR reviews across a 3-person team; zero direct pushes to protected branches.
  • Maintained near-zero staging cost using free-tier EC2 and API Gateway pay-per-request pricing, managed entirely via Terraform.
DevOps Engineer Intern

FusionPact DevOps Challenge  ·  Terraform · Docker Compose · EC2 · GitHub Actions · Prometheus · Grafana
Architecture & Infrastructure
  • Deployed a production-ready 3-tier app (Nginx frontend, FastAPI backend, SQLite) on AWS EC2 across 5 containerised services with 3 persistent volumes; zero data loss on restart.
  • Provisioned all 8 AWS resources via Terraform with zero manual console steps; user-data bootstrapped the full stack on launch.
Observability & Security
  • Configured Prometheus (15s scrape), Grafana dashboards, and Node Exporter; validated against 200+ test requests for real-time visibility.
  • Secured with SSL/TLS via Let's Encrypt, Nginx on port 443, GitHub Secrets; 2-stage pipeline deployed on every git push end-to-end in 48 hours.
DevOps & Cloud Engineer Intern
Jan 2025 to Sept 2025
HNG · M4ace · HUG Ibadan Terraform Program · Meshery Contributor
Infrastructure & Containers
  • Automated multi-environment AWS infrastructure (dev/prod) using Terraform modules covering EC2, VPC, NACLs, and auto-scaling; cut environment provisioning from hours to under 10 minutes.
  • Containerised a FastAPI application using Docker and deployed it on AWS EC2 with Nginx as a reverse proxy; CI/CD pipeline triggered deployments on every merge to main.
  • Managed Kubernetes clusters across deployment, scaling, and monitoring of containerised workloads with service discovery and auto-scaling across multiple environments.
  • Monitored system performance using Node Exporter, Blackbox Exporter, Prometheus, and Grafana enabling real-time visibility and proactive incident response.
Documentation & Open Source
  • Published 3 technical articles on Hashnode covering NGINX on AWS, multi-environment infrastructure, and modern web deployment pipelines. Contributed docs to the Meshery open-source project.

Multi-Environment Web Infrastructure
TerraformAWS VPC ALBRDS MySQL Auto ScalingCloudWatch
  • Built a production-ready 3-tier AWS architecture (ALB, Auto Scaling Group, RDS MySQL) across 2 AZs using modular Terraform; separate dev and prod environments from the same codebase.
  • Configured CloudWatch alarms and SNS notifications; validated by stress-testing the ALB endpoint and observing instance count changes in real time.
  • Reusable Terraform modules reduced config duplication across environments by over 70%.
Aug 2025
Modern Web Deployment Pipeline
TerraformNetlify HCP TerraformGitHub
  • Deployed a responsive portfolio site to Netlify using Terraform with HCP as the remote state backend; automatic deployments triggered on every git push.
  • All secrets managed exclusively through HCP Terraform workspace variables; zero credentials committed to the repository.
  • Built for the HUG Ibadan Terraform Challenge; documented in a full Hashnode article covering architecture, secret management, and team collaboration.

High Availability & CI/CD Pipeline
AWS RDS Multi-AZGitHub Actions MavenSonarCloud NexusCodeDeploy
  • Validated zero-downtime RDS Multi-AZ failover across 3 forced AZ failovers with 0 connection failures, avg recovery ~60s.
  • End-to-end pipeline completed in 85 seconds: Maven build + SonarCloud quality gate + Nexus artifact publish + CodeDeploy blue/green across 2 instances.
