Summary

Rockstar🎓
Top SchoolMarek Stepniowski is a software engineer with 17 years of experience building scalable web applications, data processing pipelines, and user-facing single-page apps across startups and large tech companies. He has shipped production systems at Google, Amazon (EBS monitoring), Datadog, Ro, and more recently Suno, combining backend architecture, database optimization, and pragmatic UI design. Marek enjoys preventing code from turning into “spaghetti,” favoring clear interfaces and maintainable designs that make systems easier for humans to understand. His work at SetJam produced a multi-source TV/movie normalization service with sub-2% error using ensemble classifiers, and he’s contributed tutorials and documentation to beginner-friendly Django resources. Comfortable spanning AI/data-mining algorithms to API design and large XML processing, he consistently ventures outside his comfort zone to learn new tools and improve developer experience. Based in New York, he pairs deep technical breadth with a communicator’s mindset that prioritizes clarity and long-term quality.
