Summary
🤩
Rockstar🎓
Top SchoolAlex U is a seasoned C and C++ systems programmer with 11 years of professional experience building cross-platform software for Windows and Unix environments. He has worked at the National Center for Biotechnology Information (NCBI) in two separate stints and spent five years at Amazon, demonstrating experience across both research-focused and large-scale production organizations. His open-source contributions include backend work on the widely used ncbi/sra-tools, where he implemented an efficient utf8-like integer codec and handled complex branch merges and comparator optimizations. Alex’s strengths lie in low-level performance engineering, toolchain and build improvements, and integrating changes safely into established codebases. Trained with a Master’s in Computer Science from Novosibirsk State Technical University, he combines strong algorithmic foundations with pragmatic engineering for bioinformatics and infrastructure projects. Notably, his profile reflects a tendency to improve core data representations and compilation workflows—small changes that yield significant system-wide benefits.
