About Pere Joan

Ingeniero de software con más de 6 años de experiencia desarrollando APIs, chatbots y soluciones cloud. Me especializo en crear sistemas backend fiables, convertir ideas de producto en software funcional y mejorar plataformas existentes con un enfoque práctico y orientado a negocio. Combino experiencia técnica con visión de proyecto, lo que me permite colaborar con fluidez tanto con perfiles técnicos como no técnicos. Trabajo en remoto, con una comunicación clara, mentalidad estructurada y foco en entregar soluciones mantenibles que resuelvan problemas reales.

Últimamente he estado también trabajando mucho con agentes de IA, ya sea en mi propio flujo de trabajo o montando agentes y equipos de agentes OpenClaw para automatizar ciertas tareas.
