Alena Gusakov
Student
Summary
🤩
RockstarAlena Gusakov is an MMath student in Combinatorics & Optimization at the University of Waterloo with eight years of hands-on software engineering experience and a strong focus on formal mathematics and backend development. She has contributed substantially to the leanprover-community mathlib3 library, adding and refactoring combinatorics and category theory components such as matchings, perfect matchings, degree-sum formulas, and complement graph modules. Comfortable working in proof-assisted development, she blends rigorous mathematical reasoning with practical code hygiene to evolve a widely used formal mathematics codebase. Alena’s background suggests she thrives at the intersection of theoretical math and production-grade software, bringing precision and long-term maintainability to complex code.
