La aplicación, construida sobre la plantilla Base 44, ya superó el desarrollo principal y se encuentra en plena fase de integración. Necesito darle continuidad para que llegue a producción sin contratiempos. Trabajo pendiente • Interfaz de usuario – optimizar la experiencia del usuario en pantallas de pasajero y conductor, corrigiendo cualquier detalle visual que reste fluidez. • Funcionalidades del backend – cerrar endpoints restantes y afinar la lógica de emparejamiento conductor-pasajero, cálculo de tarifas y gestión de viajes. • Integración de pagos – incorporar y probar el gateway que utilizamos en Argentina (p. ej. Mercado Pago) hasta dejarlo operativo en ambiente de pruebas y luego en vivo. Flujo de trabajo esperado 1. Revisión del código actual (frontend + backend) y planificación breve de hitos. 2. Implementación incremental con entregas semanales para que pueda validar cada módulo. 3. Pruebas integrales en staging; pasaremos a producción cuando la app funcione de extremo a extremo sin errores. Criterios de aceptación • La app debe permitir crear, aceptar y completar un viaje con cobro electrónico exitoso. • UX fluida en los principales dispositivos Android e iOS que usamos en Argentina. • Código documentado lo suficiente para que otro desarrollador pueda retomar fácilmente. Si tienes experiencia real en proyectos de movilidad, arquitectura client-server y pasarelas de pago locales, me ayudarás a cerrar este tramo con rapidez y

Hi, The critical part here is not just continuing development, but closing the full ride flow correctly: matching, fares, trip states, and payment handling without breaking the passenger and driver experience. For an Uber-like app, small backend or payment issues often only appear in staging, so I’d review the current logic before making more UI changes. My first step would be to audit the existing Base 44 code, separate what’s missing in frontend vs. backend, and work in small milestones so you can validate each module. Then I’d prioritize create/accept/complete trip flow, integration with the local Argentina payment gateway, and edge-case testing on Android/iOS, especially for payment failures, cancellations, and inconsistent states. Key focus: Review current code Complete pending endpoints Refine matching and fare logic Integrate and test payments Polish passenger and driver UX Timeline: I can start with an initial audit right away and then move through the core ride and payment modules in short, reviewable phases. One quick question: does the backend already persist trip states and payment events, or should that be modeled from scratch?

Hi there, As an experienced mobile app developer with a strong background in Android and iOS, I feel confident that I can not only deliver the remaining functionalities needed for your Continuar App in a timely manner but also optimize its user interface to provide a seamless experience. I've developed numerous applications in the past decade, including those with complex backend logic and payment gateway integration as needed for your project. I can effectively utilize and modify existing code bases - like implementing the missing endpoints on your current app - while also creating new components to meet specific needs - such as making seamless use of the selected payment gateway, in this case Mercado Pago. To ensure a smooth working relationship and successful project completion, my approach is highly organized. I emphasize clear communication, thorough planning to define milestones and steady implementation with regular updates. These help us identify and resolve issues quickly before they become larger problems. Let’s collaborate to make your Continuar App before defined deadlines and ensure it functions without any hitches from end to end. Thank you for considering my application.

Hi I understand your Base 44 application is already built and now you need an experienced developer to finalize backend logic, improve UX for passenger and driver flows, and fully integrate Mercado Pago to bring the system into production with a stable end to end ride and payment process. I am a full stack AI and web developer with strong experience in mobile app development, backend APIs, and payment gateway integrations. I have worked on client server architectures involving real time workflows, transactional systems, and multi role user platforms where reliability, clean state handling, and smooth UX are critical. I also have experience optimizing existing codebases and safely continuing development without breaking current functionality. For your project, I would start with a full code review of both frontend and backend to map the current state and identify missing endpoints and logic gaps. Then I would incrementally stabilize the ride flow including matching logic, fare calculation, and trip lifecycle management. In parallel, I would integrate Mercado Pago in a sandbox environment, validate all payment states, and ensure proper handling for success, failure, and edge cases before moving to production. The goal will be a fully functional system where passengers and drivers can complete a full ride cycle with reliable payments, clean UX across Android and iOS, and maintainable code ready for future scaling. Best, Justin

Base 44 como base ya resuelve la capa visual; lo que falta es cerrar backend, pulir UX y dejar Mercado Pago operativo en producción, que es justo mi terreno habitual. - Reviso el código actual (frontend y backend) para mapear qué endpoints de emparejamiento, tarifas y gestión de viajes faltan o necesitan ajuste, y priorizo por impacto en el flujo end-to-end. - Optimizo las pantallas de pasajero y conductor corrigiendo fricciones visuales y validando el comportamiento en los dispositivos Android e iOS habituales en Argentina. - Integro y pruebo el gateway de pagos: ¿tienen ya cuenta y credenciales de Mercado Pago configuradas, o necesitan que gestione el alta y el paso de sandbox a producción como parte del alcance? Puedo entregar en el plazo de 2 semanas indicado, con hitos semanales para que valides cada módulo antes de pasar a staging y luego a producción. Toma la cifra propuesta como una referencia inicial y orientativa para el alcance descrito, no como precio definitivo; la confirmamos en cuanto aclaremos el estado real del código y las credenciales de pago. Si te sirve, agendamos una llamada breve aquí en Freelancer para repasar estos puntos, y con gusto te muestro trabajo relevante desde mi perfil.

Hi, Tu app en Base 44 ya está en integración; falta cerrar tres frentes: UX de pasajero y conductor, endpoints con la lógica de emparejamiento y tarifas, y Mercado Pago operativo en pruebas y en vivo. Mi hipótesis: lo que resta fluidez suele estar en el estado de los viajes y en los callbacks del pago, no en la UI. Empezaría revisando el código actual y armando hitos semanales para que valides cada módulo. Trabajo Flutter y nativo Android/iOS con REST APIs, Google Maps y pasarelas de pago, justo para un flujo crear-aceptar-completar viaje con cobro electrónico. Entrego código documentado para que otro dev lo retome sin fricción. Lo cierro en ~21 días, con entregas semanales y pruebas en staging antes de producción. Primer paso: revisión del repo y un plan corto de hitos. ¿Me pasas acceso al código? Regards, Nurullah Al Masum
