Data Berlin #44
Cooler air, warmer job market, and a summer reading list that won't melt.
Berlin is breathing again this week. After last week's 40°C scare, we're back to a manageable 27°C, still warm enough to work by an open window… if you enjoy the surprise rain.
The job board has been buzzing: new roles across data engineering, analytics, and AI/ML landed this week. Good timing if you're looking to lock something in before the summer slowdown.
Coming up next week: WeAreDevelopers World Congress (Jul 8–10) — we have a 20% discount with code Community_DataBerlin.
And if you're around, we are planning a new meetup before the school holidays. More details on our next meetup coming shortly. Stay tuned and stay cool.
