Worked on the gofractally/psibase repository to deliver a comprehensive enhancement of the Evaluation Service API and its underlying data model. The work involved refactoring the evaluation service interface, aligning function signatures throughout the evaluation workflow, and introducing robust initialization logic and service status checks. By adding new records for evaluation, group, user, and user_settings, the developer established a foundation for scalable evaluation pipelines and user-specific configurations. Utilizing skills in API design, smart contracts, and the WIT language, these changes improved data access, reliability, and developer onboarding, directly supporting business goals to streamline integration and enable future evaluation-related features.
