Full Proven Proposal Cover Letter

Hi Mark,

Slow CI/CD pipelines kill team velocity. I specialize in optimizing Docker builds and GitHub Actions workflows.

Optimizations:
- Multi-stage builds reducing production image sizes from 1.8GB to 85MB (Alpine/Distroless).
- Layer caching using BuildKit and GitHub Actions cache.
- Concurrent matrix test runners.

Can optimize your first 3 Dockerfiles today.

Best,
Alex
