Building SDK Kit: extracting patterns from production systems

Over winter break, I spent two and a half weeks studying JSTag—Lytics' production data collection SDK—then extracted the infrastructure patterns that let it survive scale and third-party integrations. The thesis: production systems teach composition in a way textbooks can't. SDK Kit validates those patterns through Auth HI! and Experience SDK.
