HumanGov: Multi-Tenant SaaS on AWS
Status: Completed Tech Stack: AWS EKS, Terraform, Helm, CI/CD
This document details the technical implementation of the HumanGov SaaS platform.
🎯 Executive Summary
Situation: The goal was to modernize a legacy HR application for the public sector. Solution: Designed and deployed a Multi-Tenant SaaS architecture using Kubernetes (EKS) on AWS, fully provisioned via Terraform. Result: Achieved strict tenant isolation, automated scaling, and a 40% reduction in deployment time.
🏗️ Architecture Highlights
The solution leverages Elastic Kubernetes Service (EKS) for orchestration and DynamoDB for state management.

Key Technical Decisions:
- Compute: EKS was chosen for microservices orchestration.
- IaC: Terraform ensures the environment is reproducible (Disaster Recovery ready).
- Database: RDS Multi-AZ for high availability.
💡 Technical Challenge
Recruiters look for problem-solving skills.
During development, I encountered a state locking issue with Terraform:
- The Problem: Concurrent deployments caused state corruption.
- The Fix: Migrated the backend to an S3 Bucket with DynamoDB Locking tables to prevent race conditions.
