Tengo interés en crecer profesionalmente y aportar en un ambiente moderno y dinámico. Mi aspiración salarial está alineada con el rango indicado de $2.500.000 COP más auxilios complementarios, según responsabilidades finales del cargo. ¿Qué stack usan actualmente en el proyecto para backend y frontend, además de PHP, MySQL y HTML? ¿El cargo requiere mantenimiento de un sistema ya existente o desarrollo de nuevas funciones desde cero? ¿Cuál sería el horario presencial en Cartagena y la fecha estimada de inicio? ¿El proceso incluye prueba técnica o entrevista con el equipo de desarrollo? Gracias,

Hi — Elias here from Miami. I understand you're looking for a backend and frontend developer for a project in Cartagena. The goal here seems to be creating a robust application that effectively manages both user interactions and data processing. What usually matters most here is ensuring that the system remains scalable and maintainable. A common issue in systems like this is integrating various components smoothly while keeping the user experience seamless. The tricky part is usually handling API interactions and database management efficiently to avoid bottlenecks as user demand grows. My approach would focus on structuring the application with a strong emphasis on modularity. This way, we can ensure that future features can be added without disrupting existing functionality. I’ve previously worked on similar projects where I balanced frontend responsiveness with backend reliability, which helped in achieving a solid user experience. A few questions to better understand the scope: Q1 – What specific user roles do you envision for this system? Q2 – Are there any existing systems or APIs you plan to integrate with? Q3 – What are your expectations regarding scalability and user load? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

I include 30 days of post-deployment bug-fixing to ensure a smooth launch. What specific backend framework are you currently using for this project? Let's discuss how I can contribute to your team.

Veo que están buscando a alguien que realmente pueda moverse entre backend y frontend sin quedarse solo en “hacer pantallas” o “hacer endpoints”, sino entender cómo fluye todo el sistema. En un entorno presencial eso además cambia bastante la dinámica porque los problemas se resuelven rápido entre equipo y producto. Mi enfoque sería empezar entendiendo cómo están hoy estructurados los servicios y la base de datos para detectar cuellos de botella antes de tocar código nuevo. Después organizaría el trabajo en módulos pequeños: APIs limpias, validaciones desde backend y una interfaz que no dependa de lógica duplicada en frontend. En proyectos con PHP y MySQL normalmente los errores aparecen más por consistencia de datos y manejo de estados que por complejidad técnica, así que pondría atención ahí desde el inicio. Trabajé en Aras desarrollando backend con PHP y Python integrando APIs y optimizando flujos internos para reducir procesos manuales. Estoy disponible para trabajar presencialmente en Cartagena. Mi aspiración salarial está alineada con la oferta publicada y puedo iniciar de inmediato.

My approach combines technical soundness with practical business solutions, ensuring that the final result is not only functional but also user-friendly. To ensure success, I propose starting with a detailed requirements gathering phase, followed by iterative development cycles that allow for feedback and adjustments.

Los cuellos de botella que suelen frenar equipos presenciales en Cartagena no son solo falta de código, sino APIs inconsistente, bases de datos sin migraciones y poca trazabilidad entre backend y frontend — eso es lo que hay que arreglar primero para que el equipo realmente escale. Propongo comenzar con una auditoría de 1 semana (arquitectura, endpoints, migraciones, despliegue) y luego iterar en sprints de 2 semanas: estabilizar API y modelo de datos, exponer contratos claros (OpenAPI), implementar pruebas básicas y entregar componentes frontend incrementales que consuman esas APIs. Para velocidad y mantenimiento recomiendo Laravel + MySQL para backend (estructurado, familiar y rápido de entregar), Vue o React para frontend según preferencia del equipo, Docker para entornos, Git + CI (GitLab/GitHub Actions) y Postman/OpenAPI para contratos. Pienso en código con estándares, pruebas unitarias básicas, documentación y transferencia al equipo; puedo trabajar presencial en Cartagena y adaptar entregables al contrato obra o labor. He liderado marketplaces y sistemas internos: por ejemplo, LootEdge (marketplace con KYC, escrow, Stripe/Coingate, PostgreSQL) y Zweidevs Internal (gestión interna con React/Django), ambos relevantes por integraciones API y workflows operativos. Mi aspiración salarial: 1.125 USD mensuales. ¿El rol parte de un código existente o esperan desarrollo desde cero (y pueden dar acceso al repositorio para la auditoría inicial)? Si te parece, agendamos una reunión para revisar alcance.

@amadorjay

Hello, The main challenges involve ensuring seamless integration between backend and frontend components while managing data flow across various services. Additionally, maintaining a robust API design is crucial to facilitate effective communication between different modules. What existing infrastructure can we leverage, or will we need to build everything from the ground up? How do you envision the data synchronization process, particularly in terms of real-time updates? I am ready to discuss these complexities further and contribute to a solution-oriented approach.
