Rockstar🎓
Top SchoolMaciej Zwoliński is a Senior Software Engineer based in Warsaw with eight years of hands-on experience, focusing the last four on MLOps and expanding into DevOps. He designs and ships production-grade tooling—ML frameworks, inference parallelization, monitoring, and tailored cloud infrastructure—prioritizing end-user needs through close collaboration with researchers and engineers. At ReSpo.Vision he built production environments from scratch and optimized resource usage across Google and Oracle clouds, and he now brings that productivity-engineering mindset to Splunk. His open-source work includes performance-driven Rust contributions to a zkVM project (snarkVM), showing a knack for low-level optimization in cryptographic contexts. Trained as a physicist, he combines analytical rigor with practical engineering to turn research prototypes into reliable, scalable systems.
