Rockstar🎓
Top SchoolSimon Wollwage is an infrastructure engineer with 16 years of experience building low-latency, resilient systems across finance and large-scale cloud services, currently at Woven by Toyota after a multi-year tenure at Amazon. He brings deep expertise in typesafe, functional-first programming—regularly using Rust, Haskell and OCaml—to craft robust, secure solutions and to simplify complex system behaviour. His background spans market-data feed reliability, distributed data processing and research-driven algorithm implementation from his RWTH Aachen and National Institute of Informatics work. An active open-source contributor, he implemented core data structures and workspace management for a Rust tiling window manager, reflecting a penchant for clean abstractions and careful testing. Colleagues rely on him for solving tricky engineering problems with strong emphasis on correctness, performance and maintainability.

Window Tiling For The Win. A tiling window manager written in Rust
Role in this project:
Backend Developer
Backend DeveloperContributions:388 commits, 29 PRs, 124 pushes in 6 years 3 months
Contributions summary:Simon primarily worked on the core functionality of a tiling window manager written in Rust. Their commits show the addition of essential core data structures, including windows, stacks, and workspaces. Furthermore, they implemented methods for managing and manipulating these workspaces, such as the "view" method for switching between them and "greedy_view" method. Finally, the user created the base structure for a window system abstraction layer and added tests for the event loop.
