Weeknotes 2026.36

This was a wild week. I had to prepare data for some projects, and as usual, I was a little bit late. But I managed to finish most of the things on time.

And on Thursday, we finalised the last few details for our company trip with the venues. It is always a challenge finding places for 120-130 people.

On Tuesday I had a field trip with our intern to one of our offices. She always wanted to see the rooftop garden. After the trip she was happy and impressed. Therefore, I consider it a succesful field trip.
