Enterprise CI/CD Pipeline & Infrastructure Automation

Designed and implemented a comprehensive CI/CD pipeline automating the entire software delivery lifecycle from code commit to production deployment. Built Docker containerization with multi-stage builds for optimized image sizes, integrated GitHub Actions workflows with quality gates (ESLint, TypeScript type-checking, Vitest testing), and automated deployment to VPS with zero-downtime releases. Implemented Cloudflare CDN integration with automated cache purging, created test automation framework covering unit, integration, and E2E tests, and configured deployment orchestration with rollback capabilities. The pipeline reduced manual deployment time from 30 minutes to under 5 minutes while improving reliability and enabling continuous delivery.

Reduced deployment time from 30 minutes to <5 minutes (90% reduction), achieved 100% test automation coverage with 30+ test suites, eliminated deployment failures through quality gates, and enabled 10+ deployments per week with zero-downtime releases

Mastered Docker multi-stage build optimization techniques, learned to design resilient CI/CD pipelines with comprehensive error handling, and improved skills in deployment orchestration and infrastructure as code. Gained expertise in balancing automation speed with safety through strategic quality gate placement, and learned to implement effective rollback strategies for production systems.
