¿Qué tipo de empresas ayudo?
Empresas que ya están en funcionamiento, tienen clientes, operaciones y facturación real, pero sus sistemas actuales:
- Fallan con frecuencia.
- Son lentos, inseguros o difíciles de usar.
- Están frenando el crecimiento o causando pérdidas ocultas.
No necesitas empezar de cero, necesitas arreglar lo que ya existe. Ahí es donde entro yo.
¿Qué hago exactamente?
✅ Refactorizo y optimizo sistemas existentes para mejorar su rendimiento, seguridad y estabilidad.
✅ Corrijo errores críticos que afectan operaciones, ventas o experiencia del cliente.
✅ Automatizo procesos internos para ahorrar horas-hombre y reducir errores humanos.
✅ Desarrollo soluciones nuevas cuando el sistema actual ya no da más.
✅ Integro herramientas modernas como inteligencia artificial, bots, APIs y soluciones en la nube para potenciar tu operación diaria.
⚙️ Tecnologías (si te interesa saberlo):
Back-End: [Node.js](http://Node.js) / Express, Laravel, PHP.
Front-End: Angular, [Vue.js](http://Vue.js), Ionic.
Infraestructura: AWS (EC2, SQS, SNS, Route53, Lightsail), enfoque serverless.
Bases de datos: MySQL, PostgreSQL, MongoDB.
