Guilherme Kuhn developed two foundational features for the pucrs-constrsw-2025-2/base repository over a two-month period, focusing on both backend integration and frontend interface design. He integrated a Reservations Service using Docker Compose, coordinating dependencies on PostgreSQL, Keycloak, and OAuth to ensure reliable service orchestration and secure initialization. Additionally, he delivered a React-based Class Management Frontend Interface, enabling CRUD operations with filtering and pagination for the admin module. Working primarily with JavaScript, TypeScript, and YAML, Guilherme’s contributions established robust deployment workflows and a scalable UI foundation, though the work was limited in scope and did not include bug fixes.
