Over four months, Georgios Evangelou contributed to the ls1intum/Artemis repository by delivering targeted improvements to data integrity, API design, and reporting reliability. He refactored core API endpoints using Java and Spring Boot, introducing Data Transfer Objects to standardize boundaries and prevent circular references, while also developing a Python script to measure DTO coverage. Georgios enhanced grading and attendance analytics by refining numeric input handling and data filtering, and improved user profile stability by safeguarding image updates. His work demonstrated depth in backend development, code analysis, and TypeScript integration, resulting in more maintainable APIs and robust data flows across Artemis features.

May 1, 2025May 2025 summary — Artemis (ls1intum): Delivered two critical bug fixes that significantly improved data accuracy and reporting reliability. Grading System: corrected rounding and interval display by using raw numeric inputs and precise interval calculations, ensuring accurate upper/lower bound updates. Attendance reporting: refactored average attendance to exclude canceled sessions and entries without counts, boosting reporting reliability. Impact: more trustworthy grading and attendance analytics, reduced need for manual corrections, and improved data integrity for instructors and administrators. Technologies/skills demonstrated: robust numeric input handling, interval-based calculation logic, and data filtering applied to core reporting paths in Artemis.
