Acerca de este Servicio
Traducción automática
¿Herramientas de IA que te crearon un prototipo que falla con usuarios reales? Yo construyo aplicaciones SaaS y web full stack listas para producción que realmente escalan, no solo demos.
He desarrollado software real durante años, incluso antes de la era de la IA, así que diseño la base correctamente y luego añado IA encima.
Lo que construyo:
- Aplicaciones web full stack y SaaS que manejan usuarios reales y pagos
- IA en tus chatbots, agentes de IA, búsqueda y automatización
- Chatbots entrenados con tus propios documentos y datos
- IA de voz y teléfono que responde llamadas y agenda citas
- IA que realiza acciones reales en tu app, no solo chat
- Backends y bases de datos personalizadas diseñadas para escalar
- Apps móviles para iOS, Android y multiplataforma
- Inicios de sesión seguros, roles de usuario y pagos con Stripe
- APIs e integraciones que conectan tus herramientas
- Rescatar y reconstruir apps rotas generadas por IA o codificadas con vibe
- Despliegue en producción y código fuente de DevOps, tú decides
También desarrollo MVP de AI SaaS, ajusto modelos personalizados, entrego apps móviles y rescato apps rotas codificadas con vibe (Lovable, Cursor, Bolt, Replit).
Tecnologías: JavaScript, TypeScript, React, Next.js, Node.js, Express, Python, FastAPI, MongoDB, PostgreSQL, Supabase, OpenAI, Claude, Gemini, LangChain, n8n, AWS, GCP, Docker, Kubernetes, CI/CD.
