End-to-End DevOps 3 tier Platform Setup

What you're getting

A complete, production-grade three-tier application platform built from scratch on AWS — not a template, not a clone, not a tutorial follow-along. I will set up the entire infrastructure layer by layer, document every decision, and hand it over to you with a living setup guide you can actually understand and extend.

I had built a similar stack on top of a real MERN TypeScript application (TravellerHub) so every layer — frontend, backend, database — has real traffic flowing through real infrastructure.

What I will build for you

Tier 1 — Presentation layer

1. React frontend containerised with Docker
2. Served through a properly configured ingress controller
3. CI pipeline wired to GitHub via webhook for automatic builds

Tier 2 — Application layer

1. Node.js / Express backend running as Kubernetes deployments
2. Jenkins master-worker architecture handling the full build and deploy pipeline
3. Helm charts for clean, repeatable deployments
4. ArgoCD for GitOps-based continuous delivery

Tier 3 — Data layer

1. MongoDB running as a managed or self-hosted instance
2. Persistent storage configured with proper volume management
3. Secure internal networking so the database is never publicly exposed

Cloud & infrastructure foundation

1. Custom VPC with public and private subnets from scratch
2. Security groups, IAM roles, and EKS cluster configured with least-privilege access
3. EC2-based Jenkins nodes with a connected master-worker setup
4. Every AWS resource created manually — no Terraform magic hiding what's actually happening

What you receive at the end

1. Full GitHub repository with all config files, Helm charts, Jenkinsfiles, and manifests
2. A detailed setup guide covering every phase — what was built, why it was built that way, and how to modify it
3. Real troubleshooting notes from actual debugging sessions — not a cleaned-up happy path
4. A working platform you can demo, extend, and talk about confidently in any DevOps or SRE interview

Who this is for

1. Engineers who need a real, explainable portfolio project — not something they copy-pasted from YouTube
2. 0–3 year DevOps engineers preparing for product company interviews
3. Anyone who has done courses but never deployed something end-to-end on real cloud infrastructure

Why buy this instead of building it yourself

Building this from scratch takes weeks of debugging, wrong turns, and documentation rabbit holes. I've already done that — the broken Jenkins configs, the Kubernetes networking issues, the IAM permission errors at 2am. You get the result without the pain, with full transparency into every decision so you can learn from it, not just use it.

5 years of SRE experience at Oracle and Zeta went into how this is structured. It's not a beginner's guess at what production looks like — it's as close to the real thing as a portfolio project can get.
