Rockstar🎓
Top SchoolOnur Sumer is a software engineer with 14 years of experience based in New York, currently building backend systems at Memorial Sloan Kettering Cancer Center. He combines strong backend Java expertise with front-end contribution experience, having improved rendering, touch support, and compound-node handling in the popular cytoscape.js visualization library. Onur has also contributed meaningful backend refactors and data-processing improvements to cBioPortal for Cancer Genomics, showing a knack for working on research-grade, open-source biomedical projects. With an M.S. from Bilkent and a B.S. from Hacettepe, he blends academic rigor with production-focused engineering and an eye for clean, testable code. A less obvious strength is his comfort moving between client-side rendering subtleties and server-side data binning, making him effective across the full stack of data-driven applications.
