Always better when we learn together. SymfonyCon Warsaw 2026 is happening November 26-27, bringing developers together for 3 tracks of presentations and informal networking.
🎤 Speaker announcement
We are delighted to welcome Jonas Kröger, Senior Director, Customer Solutions, Upsun, as he takes the stage with his talk Works on my machine. The agent said so.. We can't wait to share his insights with you!
"What it takes to run coding agents in production across your team.
Every team has a coding agent that ships great code on someone's laptop, and that stops working once the whole team relies on it. Drawing on what we learned running (and building) a software factory at Upsun, we'll dig into a few problems: sandboxing untrusted code, keeping non-deterministic models on a deterministic track, giving agents shared context instead of per-developer prompt files, and evaluating agent work beyond "the tests passed."
Click here to see more talks. The full schedule will be unveiled step-by-step over the coming weeks. Stay tuned!
A special thanks to Upsun for sponsoring this 3rd track on November 27th.
