Hi! My name is Marcin Mierzejewski, and I’m a software executive and systems architect focusing on building and scaling engineering teams, creating leaders, and delivering innovative products. I specialize in cloud computing, large-scale and distributed systems.

Most recently, I run the OpenX engineering site in Krakow and managed engineering teams working on low-latency (<100 ms) and large-scale distributed (10,000 VMs/120,000 vCPU) ad-exchange platform processing over 1M requests, 50M events, and 17 GB data per second.

Previously, I was CTO at Mezzobit (acquired by OpenX) and Neubloc (software house). Also, I had served in senior engineering roles at Fujitsu (machine learning), Aptiv (hard real-time firmware), and Motorola (high-availability embedded systems).

If you want to reach out to me, you can do it via LinkedIn, GitHub, Twitter or Instagram.
