About Guillermo
Ayudo a empresas y startups a desarrollar, mantener y mejorar aplicaciones web modernas, especialmente con Angular y TypeScript. Puedo encargarme de nuevas funcionalidades, interfaces responsive, integración con APIs, resolución de incidencias, refactorización y optimización del rendimiento.
También trabajo con Node.js y Python cuando el proyecto requiere tareas de backend, automatización o procesamiento de datos. Me diferencio por combinar experiencia frontend con flujos de desarrollo asistido por IA, utilizando Codex, OpenCode, GitHub Copilot, agentes, skills y MCP para avanzar con rapidez sin perder control sobre la calidad del código.
Puedo colaborar en desarrollos evolutivos, mantenimiento de aplicaciones existentes, migraciones, prototipos, herramientas internas y proyectos web de principio a fin.
