Sub‑100-ms APIs emerge from disciplined architecture using latency budgets, minimized hops, async fan‑out, layered caching, circuit breakers, and strong observability.

Continuous learning, adaptability, and strong support networks are the foundations for thriving teams, Matthew Card mentioned.

By fostering growth, psychological safety, and accountability, people-first leadership drives resilience, collaboration, and performance.
