About me
Marcin
Matłacz.
Senior Software Engineer at Waymo
Based in Warsaw, Poland
From machine learning
to systems at scale.
I like understanding how the pieces fit together. My path runs through machine learning, software engineering, and distributed systems.
At Waymo, I work on system-wide testing and performance across services. Outside work, I explore interfaces and turn ideas into tangible side projects.
