AWS

Internal specs were scattered across Confluence, Jira, and Figma, and finding the right rule cost real engineering time. This is how I stood up an Amazon Q Business assistant that lets the team just ask — including the IAM setup, data-source connectors, and what it actually costs.

Compressing images with Imgproxy actually slows small files down by 113–154%. Only files above 3 MB consistently benefit. Two experiments (cold and warm cache), four compression tiers, correlation analysis — and an action rule that took the guesswork out of our gateway.

Imgproxy behind AWS, Wilcoxon-tested. CloudFront → Imgproxy beats Akamai → S3 — but only after the first request warms the cache.
