Backend, web, mobile, product analytics, UX, real-time applications, interactive systems, and distribution loops.

This track contains 4 connected concepts. Mastery means explaining each
mechanism, predicting its failure modes, and supporting decisions with code,
measurements, or a reviewable design artifact.
