Juan García Carballo developed and enhanced user-facing features and backend systems across EGC-Serranito/serranito-hub and ISPP-2425-G9 repositories, focusing on data quality, user experience, and maintainability. He built a dataset rating system with real-time UI updates and authentication, refactored repository layers for clearer service contracts, and implemented automated testing using Python, Selenium, and Locust. On the frontend, Juan delivered reusable React Native components, a unified footer with animated icons, and a scalable documentation site using Docusaurus. His work included database design, API development, and security improvements, resulting in more robust data exposure, streamlined onboarding, and consistent branding across applications.

April 2025 monthly summary for ISPP-2425-G9/frontend. Key delivery: Unified Footer UI with persistent navigation across home and main tab views, with animated social icons and a refined terms modal. Implemented as a reusable Footer component and AnimatedIcon, enabling consistent branding across the app. Tech stack demonstrated: React/TypeScript component architecture, CSS animations, responsive layout, and solid Git-based traceability. Impact: improved navigation consistency, reduced user friction, and a cohesive branded experience across all views. Commits captured: eebc12b6445d3cd2cea8b8f303c956b2bcc5c237, 3f45de257794ced918a1cb16ac588fe23356638a, 69bf5eda3d22634c19a4bfacacc39f70bda659d4, 0673617f689ecccae60194451a1d9bd62328b8d5, f3725e21aa0b8246b363f148d76c0fc903696a6d.

March 2025: Delivered substantial cross-repo momentum across backend and frontend, focusing on data exposure, security, plan-based monetization, and user experience. Key backend data APIs were expanded with a CompanyDTO, new repository methods (find by plan, public information), and an endpoint to list premium companies. Plan management was enhanced with change plan flow, related DTOs, and a regular retrieval/expiry view, all implemented with transactional guarantees and a UML-aligned data model. Security improvements included a user password change flow and a minimum password length validation. Frontend refinements improved branding, form UX, and UI readability, while data modeling and seeding broadened coverage of company types. Overall, these changes improved data discoverability for customers, reduced security risk, and strengthened the platform’s adaptability for pricing and scale.
