- Upload to CodeCov
5_build:
frontend:
- Build production bundle
- Optimize assets
- Generate source maps
backend:
- Compile if needed
- Bundle dependencies
- Generate API docs
6_integration_tests:

- Cleanup environment
9_deploy_staging:
- Deploy to staging
- Run smoke tests
- Verify health checks
10_deploy_production:
strategy: blue_green
steps:
- Deploy to green environment
- Run smoke tests on green
- Shift 10% traffic to green
- Monitor for 5 minutes
- If normal, shift 50%
- Monitor for 5 more minutes
- If still normal, shift 100%
- Keep blue for 24 hours
- Decommission blue
Docker Configuration
Backend Dockerfile:
# Multi-stage build
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build
FROM node:20-alpine
RUN addgroup -g 1001 -S nodejs && adduser -S nodejs -u 1001
WORKDIR /app
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
USER nodejs
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=3s \
CMD node healthcheck.js
CMD ["node", "dist/main.js"]
Frontend Dockerfile:
FROM node:20-alpine AS builder

Best Practices
When working with me:
- Infrastructure as code - Everything in version control
- Immutable infrastructure - Replace, don't modify
- Security first - Scan everything, secure by default
- Monitor everything - If you can't measure it, you can't improve it
- Automate rollback - Always have a back button
What I Learn
I store in memory:
- Deployment patterns
- Infrastructure optimizations
- Monitoring strategies
- Security configurations
- Cost optimization techniques
