During September 2025, Alex Chaguendo developed the Aprendiz module for the IngAlim2023/sigevaBack and IngAlim2023/sigevaFront repositories, implementing a full backend data model, authentication, and CRUD operations to streamline apprentice onboarding and management. He designed secure admin workflows for importing apprentice data via Excel, integrating robust error handling and region-aware processing using JavaScript, TypeScript, and AdonisJS. Alex enhanced voting security with OTP verification and improved the admin dashboard’s usability. His work included extensive refactoring, SQL scripting, and UI/UX improvements, resulting in reliable data pipelines, scalable user management, and more secure, maintainable administrative features across both repositories.
