Summary
🤩
RockstarGabriel Ebner is a Research Software Engineer in Seattle with 18 years of experience blending formal-methods research and pragmatic software development. He has made substantive contributions to the Lean theorem prover and the mathlib ecosystem — improving parsers, VM and tooling, fixing build/import issues, and refactoring core mathematical libraries for a widely used proof assistant. Simultaneously he ships user-facing work, for example enhancing Vieb (a Vim-inspired Electron browser) with incremental search, mouse navigation, and performance optimizations. His career across Microsoft, Carnegie Mellon, VU Amsterdam, and TU Wien reflects an unusual mix of mathematical rigor and hands-on front-end craftsmanship.

Lean 3's obsolete mathematical components library: please use mathlib4
Role in this project:Back-end Developer & Mathematician
Back-end Developer & MathematicianContributions:264 reviews, 418 commits, 166 PRs in 5 years 5 months
Contributions summary:Gabriel contributed to the obsolete mathematical components library of Lean 3. They refactored code in several files like `algebra/lattice/filter.lean` to switch from `order_pair` to `partial_order` and `data/num/lemmas.lean`, demonstrating familiarity with the mathematical definitions. Their work involved code differences across numerous files related to algebraic structures and set theory.
