A bit about me

I am a Cloud & DevOps Engineer based in the UK, with hands-on experience designing and automating cloud-native infrastructure across AWS and Azure. I hold the AWS Certified Solutions Architect – Associate certification.

My path into tech was not conventional — I made a deliberate career change and built my skills entirely through real projects: production-style deployments, CI/CD pipelines, GitOps workflows, and observability stacks. I also facilitate Kubernetes and cloud labs for junior engineers, which has sharpened how I think about documentation, communication, and building things that others can understand and maintain.

I care about infrastructure that is reliable, repeatable, and well-documented — not just infrastructure that works today.

What I Have Built

AWS Three-Tier Production Infrastructure

A full production-style AWS three-tier architecture built entirely with Terraform. Covers networking, containerised application layer, managed database, caching, security, CI/CD, and full observability — designed to mirror what a real engineering team would deploy and maintain.

Includes two break/fix scenarios: Aurora security group misconfiguration caught by a deep health check, and an ECS task failing to start due to a Secrets Manager key typo — both documented with root cause analysis.

Azure AKS CI/CD & GitOps Pipeline

End-to-end delivery pipeline from GitHub source commit to live AKS deployment. Azure DevOps handles CI — building, tagging and pushing Docker images to ACR — while ArgoCD manages CD via auto-sync, keeping build and deployment concerns cleanly separated.

Validated live updates by changing the app version and confirming automatic rollout without manual kubectl steps.

AWS EKS Hotstar Clone DevOps Pipeline

Full DevOps pipeline for a streaming platform clone — from infrastructure provisioning to deployment, security scanning, and monitoring. Jenkins pipeline triggered by GitHub webhooks runs quality checks, builds, scans, pushes to registry, patches manifests and hands off to ArgoCD.

AWS ECS Application Deployment group project

Containerised web application deployed as an ECS service on EC2 launch type, with ALB routing, target group health checks, and IAM execution roles. Resolved real deployment issues including port mismatch and unhealthy target checks — documented with cleanup steps to avoid ongoing AWS charges.

AWS Native CI/CD — Full-Stack Application

AWS-native CI/CD pipeline for a React frontend, Node.js backend and MySQL database. CodePipeline orchestrates end-to-end delivery, with CodeDeploy appspec hooks handling artefact copying, dependency installation, and Nginx/PM2 restarts on EC2.

Backend CI/CD on Render with GitHub Actions

A lightweight, cost-effective CI/CD pipeline for a backend application using GitHub Actions and Render. Demonstrates that you do not always need complex cloud infrastructure to ship reliably — the right tool for the right job.

Shows range beyond AWS — practical, fast deployment for smaller workloads without over-engineering.

Full-Stack Blogging App — CI/CD & GitOps on a Single VM

A complete DevOps toolchain — Jenkins, SonarQube, Trivy, Nexus, Docker, K3s, ArgoCD, Prometheus and Grafana — running on a single Ubuntu VM on a local machine. Deployed a full-stack blogging application with a custom domain and real-time monitoring.

Running an entire DevOps stack on one VM demonstrates deep understanding of how these tools fit together — without relying on cloud resources.

Cloudboosta Student Dashboard — GitOps Deployment

A production-style GitOps deployment of the Cloudboosta Student Dashboard. Application code and Kubernetes manifests are kept in separate repositories following GitOps best practices. GitLab CI builds and publishes Docker images, updates the image tag in the manifests repo, and ArgoCD automatically synchronises the changes to the Kubernetes cluster.

Troubleshot real deployment issues including readiness probes, image pull problems and ArgoCD synchronisation errors — and documented the fixes.

DevOps Quiz App — End-to-End CI/CD Pipeline

A containerised Node.js quiz application built to demonstrate a complete DevOps workflow from source code to Kubernetes deployment. GitLab CI builds and pushes the Docker image to a container registry, deploys to Kubernetes, and ArgoCD handles automatic synchronisation from Git — covering the full GitOps loop end to end.

Demonstrates Docker image creation, CI/CD automation, Kubernetes deployments, and GitOps delivery in a single cohesive pipeline.
