Ersin KOÇ outlines system design

- Ersin KOÇ and Olivia Wilson shared practical system‑design guidance that covers component maps, data flows, API contracts, caching, failure modes and scaling levers. - They press for production‑ready artifacts: component diagrams, runbooks, explicit failure modes, API surface contracts and caching strategies aimed at 10x traffic growth. - The posts provide a tactical checklist for engineers expanding into architecture and reliability roles through documented runbooks and measurable SLOs.
