Presentations
Alexis Lowe
Join Alexis, Principal Engineer at Moonpig, as he explains how they built a scalable Federated GraphQL backend using AWS serverless (Lambda, SNS, SQS, DynamoDB) and a federated architecture. Discover how their event-driven approach and custom caching strategies keep their system fast and adaptable for diverse client needs, along with a sneak peek at future performance improvements.

Taz Singh
Ever wonder about the full data stack powering Guild? Taz will give you an in-depth show & tell of the end-to-end architecture, covering everything from:
Database: how Postgres is used to manage & authorize deeply interconnected social data GraphQL server: how that Postgres database gets transformed into GraphQL GraphQL Persisted Operations: security & efficiency gains implemented on the server Fine-grained caching: how all data provided via GraphQL is cached for read-after-write consistency Server-side rendering: ensuring there isn't reflows / loading spinners/ re-rendering on initial load due to data fetching Client-side rendering: efficiently fetching data via Relay Data catalog: using GraphQL as a data catalog, to power all data fetching across Guild (i.e. not only the web app that you'd expect)Platform Sponsors
