What happened?

CLI-driven workflow that fingerprints incoming assets, orchestrates lossless + mild lossy passes, and writes per-file savings to a manifest that downstream jobs consume.

Tech & Impact

  • Ruby
  • Rails
  • ImageMagick
  • libvips
  • Shell

Design balances developer ergonomics (bin/setup + bin/demo) with production-ready guard rails—failing CI when a PR introduces bloated imagery while staying resilient when optimization binaries are missing.
