Build a complete full-stack application in Go, from data ingestion through persistence to a server-rendered UI, purely in Go. This full-day workshop teaches you how to design maintainable full-stack applications that age well.
We started from a working application built on a real public API: an animal-sightings site fed by GBIF records, stored in SQLite and enriched with Open-Meteo weather. From there we walked through five different architectures for the same feature (flat, layered, onion, hexagonal and feature-based) to see what domain-driven design actually buys you, then looked at how the app is built: a type-safe data layer with sqlc and a front-end written with templ. The build is a guided walkthrough of real, finished code, so the time goes on the decisions rather than the typing.

What attendees built
The hands-on part came last. Every attendee forked the workshop repository, profiled it under load with pprof and themed their own copy of the site using the /design-site skill in Claude Code or JetBrains Air, with two competitions running alongside: Best Website and Best Social Post. Thirty-three themed sites made it into the
showcase, each served exactly as its author shipped it.
