Hajir
Hajir developed core AI-driven learning and content generation features for the nova-omnia/lernello repository, focusing on scalable multilingual support and robust backend architecture. Over four months, Hajir engineered end-to-end workflows for LearningKit and LearningUnit management, integrating Java Spring and SvelteKit to deliver seamless UI and RESTful API interactions. The work included encapsulation refactors, DTO and service layer enhancements, and the introduction of AI-powered block and theory generation using GPT-4o. By implementing internationalization, PDF processing, and rigorous validation, Hajir improved maintainability, data integrity, and user experience, while ensuring the codebase remained clean, modular, and ready for future expansion.

Apr 1, 2025April 2025 – Nova-omnia/lernello delivered AI-driven theory block capabilities, modernized UI, and a cleaned API surface, driving faster content creation and global-ready UX. Key features shipped include TheoryBlock introduction with updated Carta integration; AI Theory Block Core Engine with endpoints and multi-file content generation; AITheoryBlock UI (MultiSelect, topic input) with i18n; API/DTO refactors removing legacy learningUnitId; and data handling improvements including PDF text extraction. Major bugs fixed included language display fallback issue, removal of unused TheoryBlock code and API surface, and data loading/UI bugs (e.g., include allFiles, MultiSelect case sensitivity). Overall impact: increased authoring velocity, more reliable AI-generated content, reduced technical debt, and a stronger foundation for future AI-enabled blocks. Technologies/skills demonstrated: AI/ML integration (GPT-4o), REST services, DTO/mappers, internationalization, UUID-based data models, PDFBox, and stateful UI patterns in Svelte."

Mar 1, 2025March 2025 delivered core Lernello Learning Domain capabilities with Folder/Instructor interactions via LearningKit and LearningUnit, including DTOs, mappers, repositories, services, and controller scaffolding. Built Lombok-based boilerplate reduction, cleaned up documentation and code structure, and implemented robust validation and unit tests. Refactors aligned persistence with Jakarta standards, enhanced authentication DTOs, and tightened security-related validations. Incremental but impactful improvements across blocks (Block/TheoryBlock) and ongoing code quality enhancements.
