DevOps CI/CD Transformation
Case study: CI/CD transformation from Jenkins to GitHub Actions with GitOps. 80% faster deployments, 95% fewer failures, and 90% automated test coverage.

Project Overview
The engineering team was struggling with slow, unreliable deployments. Legacy Jenkins pipelines had accumulated years of technical debt, manual steps were required for production releases, and there was limited visibility into what was running where.
We led a complete transformation of the CI/CD infrastructure, implementing modern GitOps practices and automation.
Implementation Approach
The transformation was done incrementally to minimize disruption:
- Assessment: Documented existing pipelines and identified pain points
- Foundation: Set up new GitHub Actions infrastructure and Kubernetes clusters
- Migration: Moved services one at a time with rollback capabilities
- Automation: Added testing, security scanning, and quality gates
- Observability: Deployed monitoring and alerting for all pipelines
Key Capabilities
The new platform delivered enterprise-grade CI/CD features:
- Custom Dashboard: Purpose-built interface for teams without direct GitHub access
- Progressive Rollouts: Canary deployments with automatic rollback on failure
- Quality Gates: Automated testing, security scanning, and code review requirements
- Full Visibility: Real-time dashboards showing deployment status across all environments
!Challenges
- Legacy Jenkins pipelines with technical debt
- Manual deployment processes
- Low test coverage and quality gates
- No rollback capabilities
- Limited visibility into deployments
Solutions
- Migrated to GitHub Actions with GitOps
- Implemented progressive rollouts with Argo
- Built comprehensive testing pipelines
- Created automated rollback procedures
- Deployed observability stack with Prometheus
