During a three-month period, ACPerez5 developed and enhanced user authentication, data validation, and search features for the rseangueco/CMSC128 repository. They implemented secure session management and registration validation using React, Node.js, and MongoDB, integrating frontend and backend through API calls with token-based authentication. Their work included refining Mongoose schemas for data integrity, streamlining user onboarding with improved form validation, and replacing alert-based messaging with React Toastify toasts for better user feedback. ACPerez5 also addressed routing and data seeding issues, resulting in more reliable navigation and consistent development environments. The work demonstrated solid backend and frontend engineering depth.

May 2025 – CMSC128: Delivered two major features focusing on authentication UX, session management, and registration validation. Implemented secure header-based user data fetch, token-included API requests, and toast-based feedback; streamlined registration by removing user_id and hardening validation rules. Replaced alert-based messaging with toasts across auth flows (login/logout) with bottom-right placement and styling improvements. Consolidated session management for better reliability and maintainability. Result: improved security, smoother onboarding, and a more maintainable codebase.

April 2025 (2025-04) — Key features delivered include a User Authentication System with frontend-backend API integration, Advanced Account Search and Filtering with server-side support, and Routing Parameter Cleanup to simplify navigation. Major bugs fixed involve routing parameter cleanup across the app and improvements to the graduation year filter and console warnings. Overall impact: improved security and user experience for authentication; faster, more accurate user discovery via enhanced search; cleaner URL structure reducing navigation errors and maintenance overhead. Technologies/skills demonstrated: React/Frontend integration with asynchronous API calls and error handling, server-side filtering and DB integration, routing and UI refinements, and proactive bug fixing.

Monthly summary for 2025-03 (Repository: rseangueco/CMSC128). Key features delivered: Data Model Validation and Seed Data Integrity. Implemented basic validation rules in Mongoose models to enforce data integrity (field formats and required constraints) and fixed data seeding/schema issues to align seed data with updated structures. Major bugs fixed: Seeders were misaligned with the updated schemas; fixed seeders and adjusted datatypes for text fields to match new model definitions. Overall impact and accomplishments: Improved data quality and consistency across development and testing environments, reduced runtime errors due to schema mismatches, and faster onboarding for new developers. Strengthened alignment between code and seed data, enabling more reliable data-driven testing. Technologies/skills demonstrated: Node.js, Mongoose validation, MongoDB data modeling, data seeding/migration, commit-level traceability and attention to data integrity. Benefits to business/value: Higher reliability of development and QA environments, fewer seed-related issues, smoother feature validation and iteration.
