PROFILE
Peter Stenger
Worked on the PrairieLearn/PrairieLearn repository, delivering 77 features and 15 bug fixes over eight months focused on maintainability, accessibility, and developer experience. Led TypeScript migrations across frontend and backend, introduced Zod-based schema validation, and modernized the UI framework using React and Preact. Enhanced CI/CD pipelines with Vitest and GitHub Actions, improved test reliability, and streamlined onboarding through expanded documentation and automated setup. Addressed accessibility in drawing components, implemented code linting with ESLint and Ruff, and refactored core modules for type safety and performance. Utilized Python, TypeScript, and Docker to support robust, scalable development and accelerate feature delivery.

24 Commits • 14 Features
Jul 1, 2025July 2025: PrairieLearn/PrairieLearn delivered a major UI framework refactor and stronger client-side data modeling, enhancing maintainability, UX, and reliability. Highlights: Asset consolidation and UI framework refactor; client-side data serialization and schemas with Zod; type-safe data models refinements; linting/tooling and accessibility improvements; UI/UX polish (disable student assessment switcher). Notable fixes: mobile styling for student assessments; schema listing completeness in db-types. Impact: faster development cycles, fewer runtime errors, improved student experience, and stronger data integrity. Technologies: TypeScript, TSX, React PageLayout, Zod, safety through Pick-based types, ESLint/react-hooks/jsx-a11y/html-eslint, Python venv standardization, and CI/server utilities.
