Kaspar contributed to the ToposInstitute/CatColab repository by building collaboration features and improving backend reliability. He developed an API-based workflow and UI enhancements that allow users to duplicate view-only documents into editable copies, streamlining collaboration and onboarding. Using React and TypeScript, he refined the permissions interface with tooltips for clearer user guidance. On the backend, Kaspar improved environment configuration by replacing unsafe error handling with more informative messaging in Rust, reducing runtime failures. He also automated backend setup with Docker and CI/CD, introduced flexible database configuration using dotenvy, and enhanced documentation, demonstrating depth in both frontend and backend engineering practices.
October 2025 - CatColab Backend: Streamlined developer onboarding and migrations configuration for robust, scalable environments. Implemented backend development environment setup with a default .env.development (DB + Firebase configs), refined onboarding steps, and Docker-based PostgreSQL guidance; added a CI job to install and configure the backend toolchain (Rust, pnpm, wasm-pack, Docker) and apply migrations during setup; migrated tooling to load DATABASE_URL via dotenvy from .env or system vars for flexible DB configuration. This work reduces onboarding time, ensures environment parity across local/CI/dev/test, and lowers migration risk.

September 2025 (ToposInstitute/CatColab) focused on strengthening environment configuration handling for Firebase integration. Implemented a safer startup path by replacing a potentially panicking unwrap with a safer expect when FIREBASE_PROJECT_ID is missing, producing clearer error messages and reducing runtime failures during startup. This change aligns with broader reliability and developer experience goals and is tracked by commit b889f9daa5ce68cca05de6f87d149f9edee064d0 (CLEANUP: Improve error when `FIREBASE_PROJECT_ID` is unset (#734)).
