About Benjamin
MVP Builder: de tu idea a un producto real. Sprints semanales, comunicación continua. Next.js · Firebase · AWS.
Ayudo a founders y empresas a convertir ideas en productos reales — funcionales, estéticos y listos para escalar.
Si tenés una idea y necesitás saber si tiene viabilidad en el mundo real, trabajo con vos desde el primer día: planificando, construyendo y entregando resultados concretos cada semana.
Cómo trabajo:
Semana 1: llamada de discovery + desglose completo del proyecto — stack, arquitectura, alcance y timeline claro
Reuniones semanales o bisemanales para revisar avances, ajustar prioridades y garantizar cero sorpresas
Entregas por sprints — cada semana ves features reales funcionando, no promesas
Comunicación continua — respuesta rápida, sin tiempos muertos
Qué obtenés al finalizar:
Un producto que funciona, que se ve bien y está construido para crecer
Código limpio y documentado, transferible a cualquier equipo
Stack: Next.js · React · Firebase · AWS (Lambda, API Gateway, Cognito) · TypeScript
He trabajado en plataformas e-commerce, SaaS, integraciones cloud y sistemas internos para clientes en España. Mi objetivo no es solo entregar — es que tu proyecto funcione.
