πŸ“’ Speakers & Talks

β€’ Talk #1: War stories of scaling Supabase's Realtime
Speaker: Filipe CabaΓ§o – Senior Software Engineer @ Supabase

Using Supabase Realtime as an example we will be doing a deep dive into what breaks, how to detect it and the mitigations of scaling a globally connected Elixir application for realtime applications in a showcase of how powerful Elixir and the ecosystem is when it comes to create complex services.

β€’ Talk #2: Building Modern Apps with Phoenix and TanStack DB
Speaker: Valter Balegas – Co-Founder & CTO @ ElectricSQL


Sync engines are the secret sauce behind lightning-fast, collaborative apps with great user experience, like Figma and Linear. While adopting a sync engine might sound like a paradigm shift, if you're building a Phoenix app with Postgres you can start using sync today.

In this talk I'll show you how to build apps using Phoenix.Sync, a library that brings real-time sync to Phoenix, and TanStack DB, a client-side embedded database that will make you forget about state transfer.
