I'm Lukas Klein. Software developer, founder, DJ, and marathon runner.

I'm a software developer specializing in Django and ReactJS, with a deep passion for building things that make complex technology accessible. I co-founded Datacake, a low-code IoT platform that helps tens of thousands of users across 55+ countries connect devices, visualize data, and build IoT applications — no programming required.

As CTO at Datacake, I work on everything from our core platform architecture to the integrations that power LoRaWAN, NB-IoT, and MQTT connectivity. We handle over 20 million records per day, and I love the challenge of scaling infrastructure while keeping the developer experience simple.

Outside of work, I'm either behind the decks DJing or lacing up for my next marathon. Running has become a big part of my life — I've been chasing finish lines across Europe, from Hamburg to Berlin to Cologne, and I'm always training for the next one.

I also love tinkering with home automation (my house runs on Loxone and Ubiquiti gear) and occasionally write about the things I learn along the way on Medium.
