Quiero un calendario familiar que simplifique la organización diaria de todos en casa. Necesito: • Gestión de eventos y recordatorios para cumpleaños, citas médicas y actividades escolares. • Sincronización fluida con otros calendarios (Google, Outlook u opciones propuestas) para evitar duplicados. • Accesibilidad compartida, de modo que cada integrante pueda ver y, según permisos, editar los planes comunes desde su propio dispositivo. Plataformas clave: Android y versión Web responsive. Si posteriormente se pudiera extender a iOS, valoraré esa opción, pero no es imprescindible para este primer entregable. Personalización esperada: • Temas y colores personalizados que permitan distinguir fácilmente las agendas de cada miembro. • Etiquetas personalizadas para clasificar eventos (ej. “Salud”, “Colegio”, “Ocio”). • Alertas y notificaciones configurables (push, correo o SMS) con distintas antelaciones. Busco un desarrollo claro y bien documentado, idealmente con un prototipo funcional que pueda probar en mi entorno familiar. Agradeceré sugerencias sobre la pila tecnológica y sobre buenas prácticas para la seguridad y la privacidad de los datos.

Hi, Based on your requirements, I understand you want a shared family calendar where each family member can manage their daily schedule from Android or the web, with birthdays, school activities, medical appointments, reminders, and other household events available in one place. For this project, I would recommend React Native for the Android application. React Native is a good choice because the same mobile architecture can later be extended to iOS without rebuilding the application from scratch. -/ Should every family member have their own login, including children, or should parents be able to create and manage child profiles under their account? -/ When an event is synchronized from Google or Outlook, should changes made inside the family app also update the external calendar in both directions? -/ Do you need private events that only selected family members can see, alongside events visible to the whole family? -/ For reminders, should each member independently choose their own notification time and channel for the same shared event? Once I have answers to these questions and a clearer understanding of the requirements, I’ll be able to suggest the best approach, suitable technology, timeline, and accurate cost for the project. Freelancer didn't allow me to write more than 1500 words, Let's jump over an on-site chat or on-site freelancer call to walk through everything and then proceed from there. Budget and timeline are placeholder. Best regards, Tafsol MKA

❤️❤️❤️ Greetings ❤️❤️❤️ I have carefully reviewed your Multiplatform Family Calendar project and can help build a clean, reliable calendar experience with synchronization between family members and devices. I am Ozgur Ozbas, a Full-Stack Mobile Developer with 10+ years of experience in Flutter, PHP/Laravel, Node.js, REST APIs, databases, authentication, notifications and mobile application development. I can implement: • Cross-platform Flutter application • Family/group management • Shared calendar and events • Create/edit/delete events • Recurring events • Event categories and colors • Family member permissions • Calendar synchronization • Push notifications/reminders • Authentication and profile management • Backend REST APIs • Database design and synchronization logic • Responsive UI for different screen sizes • Offline-friendly handling where appropriate • Android/iOS production builds • Testing and deployment support For shared calendars, I would keep event ownership and family permissions enforced by the backend so that users can only modify events they are authorized to access. Q1. Should family members see and edit one shared calendar, or should each member have private calendars in addition to the family calendar? Q2. Do you already have a backend/API, or should I implement the backend and database together with the Flutter application?

La sincronización sin duplicados será el punto crítico de este calendario familiar. Cada evento externo conservará su ID de Google u Outlook, controlando cambios, recurrencias, zonas horarias y conflictos de edición. Propongo un prototipo con Flutter para Android, Web responsive y una futura versión iOS, apoyado por una API y PostgreSQL. Incluirá calendarios por miembro, permisos de lectura/edición, colores, etiquetas y alertas configurables. Empezaría con push y correo; SMS puede añadirse mediante un proveedor externo. Para privacidad, usaría OAuth con permisos mínimos, datos cifrados y acceso por familia y rol. El primer entregable sería funcional, documentado y fácil de probar en su entorno familiar. Prefiere que el prototipo sincronice primero con Google Calendar o necesita Google y Outlook desde la primera versión?
