Standard stacks have limits; we’re moving past them. Join us for a deep dive into high-performance, "sovereign" architecture.

We’ll explore how to bypass API dependencies by running AI agents entirely in the browser and how to inject Rust-level type safety into Go. From WebAssembly runtimes to custom language transpilers, this event is for developers looking to reclaim control over privacy, safety, and the client-side experience.

​🎤 AGENDA

18:00 – Doors Open
Get settled, grab a drink, and meet fellow builders

19:00 – Talk 1
Compiling Rust Ideas into Go: Learnings from Lisette by Iván Ovejero Software engineer at n8n

Go's simplicity is a genuine strength, and one of the hardest things in language design is adding capability without undermining it.

Lisette is a language I built that compiles to Go and interoperates with the Go standard library, bringing ideas from Rust (sum types, pattern matching, nil elimination, typed error handling) into the Go ecosystem.

In this talk, I will walk through Lisette's design, the Go code it emits, and the tradeoffs I hit along the way, to explore a broader question with the audience: how much expressiveness and safety can we layer onto Go without sacrificing what makes it such a productive language?

🍕☕ Break — 15 min
19:30 – 19:45

​​19:40 – Talk 2
3W Principle for In-browser AI Agents by Barış Güler Software Architect at Zoi

This talk explores the “3W” architecture for in-browser AI: WebLLM, WebAssembly, and WebWorkers.

It shows how local model inference, multi-language agent runtimes, and responsive browser UX can work together to run AI entirely client-side, with no API calls and no data leaving the device.

Through practical demos and architectural lessons, the session covers what this browser-native stack enables, where it still struggles, and why privacy-first, offline-capable AI may open a new frontier for web applications.
