Summary
👤
Senior🎓
Top SchoolSemen Chudakov is a Senior Software Engineer with eight years of experience now based in Kyiv and currently at Uber, bringing deep expertise in algorithms and back-end systems. He contributed as a committer to the widely used JGraphT library, implementing advanced graph algorithms (Delta Stepping, Bidirectional A*, Yen’s and Eppstein’s k-shortest paths, contraction hierarchies) and fixing subtle cases like pseudo-graphs, showing both theoretical depth and practical rigor. His career spans roles at GlobalLogic and internships at SAP, and he progressed internally at Uber from Software Engineer II to Senior Software Engineer. A computer science bachelor’s student at Taras Shevchenko National University, he blends strong academic foundations with production experience building scalable graph and routing-related features. Colleagues would note his knack for turning complex algorithmic ideas into well-tested, maintainable code that powers real-world services.
