Acerca de este Servicio
Traducción automática
No solo creo aplicaciones web, también las gestiono. ConvoSync es una plataforma SaaS B2B que construí y mantengo activamente, gestionando mensajes de WhatsApp e Instagram para empresas. Eso significa que entiendo las preocupaciones de producción que la mayoría de los freelancers omiten: manejo de errores, trabajos en segundo plano, limitación de tasa y rendimiento.
Mi stack: Frontend: React + TypeScript + Tailwind CSS Backend: Node.js/Fastify (o Express) Base de datos: PostgreSQL + Prisma ORM Autenticación: JWT, OAuth (Google/Facebook) Despliegue: listo para Vercel, Railway o tu propio VPS
Lo que he construido:
Plataformas SaaS y paneles de control,
APIs REST y servicios backend,
Paneles de administración y CMS,
Integraciones de terceros (pagos, APIs, webhooks)
Cuéntame qué necesitas y te daré un alcance honesto antes de que hagas tu pedido.

This is the third time I have contacted this team, delivering exceptionally as always. They helped identify a system error causing a production issue and were open to fixing an issue not mentioned in the initial agreement. I would definitely contact them in the future.
