Erik Reider
Bachelor's Project at Redpill Linpro
Karlstad, Sweden
Summary
🤩
Rockstar🎓
Top SchoolErik Reider is a computer science student at Karlstad University with eight years of practical software development experience, currently working on a touch-based booking system as his bachelor's project at Redpill Linpro. He is an accomplished open-source contributor in the Wayland ecosystem, having made deep backend changes to sway (an i3-compatible compositor) and added rendering features like per-application saturation in SwayFX. Erik blends low-level compositor work—input/output handling, layer shell focus, damage ring fixes—with full-stack GTK projects such as a carousel-based notification center and Waybar power module improvements. His background spans small-company engineering roles and an IT manager stint, reflecting both hands-on coding and product-minded responsibility. Comfortable across C-level compositor internals and user-facing GTK interfaces, he often bridges the gap between system-level performance fixes and polished user features. A less obvious strength is his knack for tackling tricky platform-specific edge cases, such as fullscreen saturation correctness and precise corner-radius rendering fixes.

SwayFX: Sway, but with eye candy!
Role in this project:Back-end Developer
Back-end DeveloperContributions:135 reviews, 38 commits, 78 PRs in 2 months
Contributions summary:Erik implemented per-application color saturation support within the SwayFX compositor. This involved modifying the rendering pipeline to allow for color adjustments, including implementing the necessary code changes in `sway/desktop/render.c` and `sway/desktop/fx_renderer.c`. Furthermore, the user added a new command to the configuration file to set the color saturation. The user also fixed various issues related to the new feature, such as ensuring correct application of saturation to fullscreen applications and correcting corner radius calculations.
