January 2026 monthly summary for aceleradora-TW/e-acelera-front. Delivered data integrity improvements by unifying data handling and normalizing API responses for Detailing components. Implemented standardization across DetailingThemeContent and DetailingTopicContent, aligning component data handling with API structures to ensure correct type assignment and consistent data flow.

December 2025 monthly summary for aceleradora-TW/e-acelera-front focusing on accessibility improvements in the frontend. Delivered a new Accessibility Button in the layout, refined the accessibility menu and reading mask components for a consistent design language, and reinforced code quality to support maintainability and faster future iterations.

July 2025 — Progress Tracking Enhancements for Aceleradora25/e-acelera-back: Implemented granular progress calculations at topic and theme levels, based on the number of exercises per topic, with new services and controllers to support theme-specific progress. Optimized data fetching and Redis initialization to reduce API calls and improve responsiveness. Refactored progress service tests, added theme-related tests, and cleaned up logs to improve reliability.

June 2025 monthly summary for Aceleradora25/e-acelera-back: Delivered StackBy integration and a major overhaul of the Progress Tracking workflow, enabling StackBy-based progress calculations and richer metrics for dashboards. Implemented StackByService, StackByController, and a new Route, along with environment-based constants and component renaming to StackBy, plus a new StackByEndpoint DTO to formalize data fetches from StackBy endpoints. Overhauled the progress layer with theme-based progress, a ProgressDTO, and a centralized Progress-centric workflow, integrating with the StackBy API for richer progress calculations. Refactored core services/controllers, migrated the Prisma client globally, and reorganized DTOs to support scalable progress data. Strengthened production readiness by removing seed/mocked data, moving to production-ready test data workflows, and introducing validation with class-validator/class-transformer; hardened authentication flow, standardized English messaging, and removed CORS to reduce surface area. These efforts deliver measurable business value through higher data fidelity for dashboards, improved deployment reliability, and faster feature delivery.

May 2025 highlights for Aceleradora25/e-acelera-back: Key features delivered - Progress Tracking: Enhancements and Data Integrity — robust upsert logic, elementType handling, removal of pre-save existing progress validation, and composite unique constraint (itemId_userId) to prevent duplicates. - Topic Progress Tracking — new TopicService/TopicController, route /topic/:topicId/progress, and tests; introduced calculateProgress and comprehensive validation to ensure totalItems >= 0 (including 0). - Routing and Development Environment Hygiene — centralized routing middleware usage and .vscode ignore to improve maintainability and developer experience. - User Data Access Layer — introduced UserService to centralize user data access. - Testing Infrastructure (Prisma/Jest Mocking) — added tooling to support Prisma mocking with Jest for reliable unit tests. Major bugs fixed - Progress upsert and data integrity fixes: adjusted upsert flow, removed unnecessary existing-progress checks, and aligned tests; introduced composite key to ensure data integrity. - Topic progress edge cases: corrected totalItems validation to allow 0 and prevent negative values; improved test coverage and controller wiring. - Middleware routing duplication: centralized middleware usage to avoid per-route repetition. - Testability enhancements: integrated Prisma/Jest mocking to stabilize unit tests. Overall impact and accomplishments - Significantly improved reliability of progress tracking across exercises and topics, reducing data inconsistencies and rework. - Enhanced maintainability and developer experience through centralized routing, dependency injection improvements, and a cleaner codebase. - Faster, safer deployments enabled by more robust unit tests and mocks for Prisma. Technologies/skills demonstrated - TypeScript/Node, Prisma, Jest, dependency injection, REST API design, unit testing with mocks, service/controller architecture, data integrity and upsert optimizations.
