João Rangel developed core onboarding and appointment management features for the PointTils/Frontend repository, focusing on a smoother user experience and robust frontend architecture. He revamped the onboarding flow with React Native and TypeScript, improving UI/UX coherence and reducing first-run friction. João also implemented user authentication and appointment management interfaces, enabling users to log in and manage appointments efficiently. His work included stabilizing the CI/CD pipeline through environment configuration, dependency alignment, and code formatting using Prettier. By addressing environment hygiene and maintaining consistent code quality, João ensured reliable releases and maintainable code, demonstrating depth in frontend development and continuous integration practices.

October 2025 (2025-10) monthly highlights for PointTils/Frontend. Delivered two core features and stabilized the frontend CI/CD workflow, significantly improving user experience and release reliability. Key features delivered: - User Authentication and Appointment Management UI: launched initial login UX and enhanced appointment management UI with the ability to accept/reject pending appointments and a richer appointment details view. - CI/CD Maintenance: stabilized the development pipeline via environment variable cleanup, placeholder URL removal, login toast adjustments, and dependency updates to ensure CI stability and code quality. Major bugs fixed / maintenance improvements: - Resolved CI stability issues through environment cleanup and alignment of dependencies - Code quality and linting improvements: Prettier formatting fixes, removal of unused imports (UserType), and consistent code formatting - Dependency/version alignment: synced Expo SDK (expo 54.0.17) and expo-router (~6.0.13) to prevent runtime/build issues Overall impact and accomplishments: - Enhanced user onboarding and appointment workflow, enabling faster, more reliable interactions for end users and staff - Reduced release risk and build failures through CI/CD hardening and code quality improvements - Strengthened frontend maintainability with clearer commit hygiene and consistent formatting Technologies / skills demonstrated: - Frontend UI/UX development (React/Native-style patterns) and advanced appointment management UI - CI/CD maintenance and environment management - Code quality tooling (Prettier, linting) and dependency management - Environment variable hygiene and build stability practices
