Enterprise Multi-Environment CI/CD Pipeline with AI-Driven Quality Gates
Fintech / PropTech Organization (Singapore)
Overview
Designed and implemented a comprehensive multi-environment CI/CD pipeline for a complex web application spanning microservices architecture. The pipeline features AI-driven quality gates that assess deployment risk based on code change patterns, intelligent test selection, and automated security scanning — supporting 15+ engineers with 50+ deployments per week.
Client Profile
The Challenge
Fully automated infrastructure provisioning
Security scanning integrated into the pipeline
Application deployment across development, staging, and production environments
Support for multi-architecture container builds (ARM64/AMD64)
Solution Architecture
100% IaC-Driven Setup using Terraform with modular, reusable modules. Five-Tier Environment Hierarchy with sophisticated branching strategy (develop > release > eval > master > hotfix).
AI-Driven Quality Gates analyzing code change patterns to assess deployment risk. Intelligent Test Selection prioritizing high-risk test paths based on change impact analysis.
Multi-Architecture Container Builds supporting ARM64 (Graviton) + AMD64 using Docker Buildx. Docker Layer Caching achieving 60% faster builds.
Integrated Security Pipeline: SonarQube, Dependabot, Trivy, TFSec.
