ThisIsUche is not just a portfolio website—it's a production-grade DevOps system demonstrating real-world cloud-native practices. Built as a learning platform to showcase DevOps skills through practical implementation.
✅ Full CI/CD automation - From commit to production in 5 minutes
✅ Containerized deployment - Multi-stage Docker builds with 80% size reduction
✅ Infrastructure as Code - Entire system versioned and reproducible
✅ Security scanning - Automated vulnerability detection
✅ Production-ready - Health checks, monitoring, proper logging
This project serves multiple goals:
- Portfolio Showcase - Display 10+ DevOps projects with interactive filtering
- Learning Documentation - Track my journey from Linux basics to cloud architecture
- DevOps Demonstration - Prove ability to build and operate production systems
- Knowledge Sharing - Document best practices and lessons learned

- ✅ No configuration drift
Every commit is automatically built and tested.
Pipeline Stages:
1. Lint Code (ESLint)
2. Type Check (TypeScript)
3. Build Application (Vite)
4. Build Docker Image
5. Security Scan (Trivy)Quality Gates:
- ❌ Linting errors → Build fails
- ❌ Type errors → Build fails
- ❌ Build errors → Build fails
⚠️ Security vulnerabilities → Warning (not blocking yet)
Automated deployment to production on every merge to main.
Push to main → GitHub Actions → Build → Test → Deploy → Live

Deployment Strategy:
- Zero-downtime deployments
- Automatic rollback on failure
- Instant cache invalidation
- Global edge deployment
Docker for consistent, portable deployments.
Multi-stage Build Strategy:
# Stage 1: Builder (500MB+)
FROM node:22-alpine AS builder
RUN npm ci && npm run build
# Stage 2: Production (25MB)
FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/htmlBenefits:
- 📦 80% smaller production image
- 🚀 Faster deployments
- 🔒 Minimal attack surface
- ♻️ Consistent environments (dev = prod)
No credentials in code. Ever.
Secrets stored in:
- GitHub Secrets (CI/CD credentials)
- Environment variables (runtime config)
- .env files (local dev only, gitignored)Protected:
- ✅ Docker Hub credentials
- ✅ API keys
- ✅ Access tokens
- ✅ Deployment secrets
Git workflow with meaningful commits.
