👨‍💻 About Me

Ghost in the Shell

I'm a Software Developer from El Salvador 🇸🇻 with 8+ years of experience building web, mobile, and scalable AI agent systems across the full stack.

I've always been fascinated by how technology 🌐 transforms our lives. That curiosity led me to specialize in robust architectures, and today I design systems that combine TypeScript, Node.js, NestJS, and cloud infrastructure to solve real-world problems.

I currently develop the backend for a SaaS CRM platform and design multi-agent AI architectures — hooks, skills, tool-use, and agent orchestration for intelligent automation.
