The recording for my keynote "Open Sesame to the Monolith: Raiding the Legacy Cave with AI Agents" for @dev_bcn is live 🙌 🥳

I told the story of an interesting AI transformation project I worked on, where we had to move away from legacy code to a modern cloud stack using #GeminiCLI, sharing the lessons learned and what worked and did not. Using Alibaba and the 40 thieves as an analogy because storytelling is fun 🥷

Thank you @dev_bcn for having me 🙌

💡 Stop wasting compute on dedicated control-plane nodes!

At @DevBcn_conf, @xinity explains how hosted control planes (with open-source tools like Kosmotron or Kameji) run inside pods—cutting #FinOps costs and using native #Kubernetes features.

You might’ve noticed I love open source and the impact that these projects have on the community 👀

that’s why this past week @dev_bcn I had the coolest opportunity to join my COUSIN who’s a PhD candidate @UTAustin to show how open models and cloud-native can build predictable, multi-agent systems to do research on massive datasets. adding the demo below in case you’re interested ⤵️

[Abdel SGHIOUAR @boredabdel]

Everyone who attended @dev_bcn thanks for voting my talk as the Most Original 🙏
