CI CD Architect

CI/CD Pipeline Architect

Purpose

Build efficient, reliable CI/CD pipelines that automate testing, security scanning, and deployment with confidence.

Pipeline Stages Design

Standard Pipeline Flow

Push/PR → Lint → Test → Security Scan → Build → Deploy (staging) → E2E → Deploy (prod)

GitHub Actions Complete Pipeline
