GenAI Talks, Bern Gossip, and Copilot Demos ✨
This week had a little bit of everything: travel, innovation, customer meetings, and a last-minute hackathon submission. From Munich to Bern and back to Zurich, I talked a lot about GitHub Copilot, built a tool for sharing Copilot instructions, and squeezed in just enough chaos to keep things interesting.
Monday
I kicked off the week with an early trip to Munich for an internal event centered on GitHub and GenAI. I had the chance to present GitHub Copilot and GitHub Advanced Security to a room full of CxOs—no pressure 😅. After the event, I squeezed in some work and ended the evening with dinner alongside the whole team. Great energy to start the week!
Mood of the day: Energized by face-to-face conversations and schnitzel 🍽️
Tuesday
Started my morning at the Microsoft office in Munich—what a fantastic workspace. Even better: I cancelled all my meetings and finally got some real work done. 💪 Later, I hopped on a train back to Zurich and continued working en route. Wrapped up the day with a promising call from a big-name customer interested in GitHub Copilot training. There might be a trip to Asia on the horizon 👀.
Mood of the day: Focused and slightly hyped 🚄🌏
Wednesday
The day was mostly about debugging a script to create rulesets on GitHub Enterprise repositories. Unfortunately, the GitHub API wasn't being very friendly—kept throwing request errors I couldn’t quite resolve. Classic. Later, I had a productive catch-up with a customer about a long-term project we’re working on together.
Mood of the day: Frustrated by APIs but hopeful about progress 🤖🔧
Thursday
I spent the day at Azure Bootcamp in Bern and it felt like a mini tech reunion. I reconnected with folks I hadn’t seen in ages, exchanged some juicy IT gossip, and made a few new business contacts. Oh, and I published a blog post reflecting on my first three months at Xebia—check it out here.
Mood of the day: Nostalgic and recharged 🔄🤝
Friday
It was Innovation Day at Xebia, and while the rest of the team gathered in Germany, I participated remotely from home. My project? CopilotInstructions.xyz — a simple Blazor + MudBlazor app that surfaces Copilot custom instructions submitted via GitHub issues. Close the issue and boom, it appears on the app. I also finalized and sent out slides for my upcoming LinkedIn course.
Mood of the day: Creative from the couch 🛋️🚀
Special Sunday Edition
Just when I thought the week was over, I went full last-minute-mode and submitted a project for a dev.to challenge using Postmark. The demo uses Azure Functions and AI to automatically generate email signatures. It’s small, but hey—it exists!
