10:35 Pacific DEKJ Session APIs That Can't Afford to Be Wrong: Lessons from Moving Money Fawziyah Alebiosu Software Engineer @Imprint Most API design advice assumes a forgiving environment: retries are cheap, data has a single source of truth, and a slow response is only an inconvenience. Financial infrastructure assumes none of that. Card networks give you three seconds to auth or decline. 11:45 Pacific DEKJ Session Everything I Knew About Developer Experience Is Wrong for Agents Emmanuel Paraskakis Founder & CEO @Level 250 Most of what we know about developer experience we learned from humans. Agents are a different user, and some of our best practices quietly work against them. 13:35 Pacific DEKJ Session The Schema Was Never Enough: The World in Protocols Ryan Scott Brown Principal Engineer @Crunchyroll, Previously @Red Hat, @Trek10, and @Vendia Every reliable process in the world is a protocol: auctions, double-entry bookkeeping, brokerage account transfers, or APIs. Protocols reduce ambiguity but the world remains messy. 14:45 Pacific DEKJ Session MCP Tools Influencing APIs for Agents Details coming soon. 15:55 Seacliff D Unconference Unconference: Modern API Design 17:05 Pacific DEKJ Session Stop Fighting the Remodel: API Design for Models That Outgrew Their Boundaries Aarti Gupta Staff Engineer @Netflix Every domain model has a breaking point.
