T-shirts.

T-shirts about building systems that need three microservices to display hello world. For software architects who've watched simple problems become distributed nightmares. Designs about the gap between clean diagrams and production reality, between architectural ideals and what actually ships. Works when you're defending why that monolith might actually be fine, or explaining why the new service mesh solved problems nobody had. Made for developers who know that sometimes the best architecture is the one you don't build.
