João Pereira developed and refined user-facing features across NIAEFEUP/uni, NIAEFEUP/nitsig, and NIAEFEUP/enei, focusing on UI/UX improvements, data management, and maintainability. He implemented campus-based restaurant filtering, overhauled exam and schedule interfaces, and introduced reusable component systems using TypeScript, React, and Flutter. His work included migrating local storage to ObjectBox and Hive NoSQL, modernizing codebases with TypeScript and Tailwind CSS, and enhancing CI/CD reliability. By restructuring data models, refactoring legacy code, and improving documentation, João ensured scalable, maintainable solutions that improved user experience and developer onboarding, demonstrating depth in both frontend architecture and robust data-layer engineering.

April 2025 delivered customer-facing information access enhancements, user experience refinements, and targeted technical cleanup across two repositories (NIAEFEUP/enei and NIAEFEUP/uni). The month focused on publishing essential competition documents, empowering users with relevant campus-based filtering, and reducing maintenance risk through codebase cleanup and feature removal where appropriate. The result is clearer onboarding, more relevant discovery, and a leaner, more maintainable codebase that supports faster future delivery.

March 2025 monthly summary for NIAEFEUP/uni and NIAEFEUP/nitsig. Key features delivered include UI polish and consistency across core views in uni (home view padding, exam card start times, conditional visibility of the favorite button on restaurant cards, corrected badge color mapping for schedule types, and teacher name visibility for active teachers). Additional items include Privacy Policy Update for nitsig (data handling details, local storage of user preferences, required permissions for the web extension, policy updateability without notice, and contact information), Documentation and Build Process Cleanup (clarified build process, removed outdated build instructions, and deleted old manifest.js), TypeScript Migration and Type Safety Across Core Modules (refactor background script from JavaScript to TypeScript, define interfaces for popup options, and improve type safety and code structure with format and lint), and Popup UI Improvements with Tailwind and Centralized Preferences (refactor popup UI to Tailwind, introduce a usePreference hook for managing user preferences in Chrome local storage; update default storage handling). Major bugs fixed: no major bugs reported this month; focus was on UI polish, refactors, and cleanup to improve stability. Overall impact and accomplishments: enhanced user experience, clearer data handling and privacy compliance, improved maintainability and onboarding for contributors, and a stronger foundation for future feature work. Technologies/skills demonstrated: Front-end UI/UX polish, TypeScript migration, Tailwind CSS, Chrome extension architecture, localStorage management, interfaces design and type-safety, and code quality practices (lint/format).
