What I'm looking for

I'm looking for a full-stack role where I can build production features end to end, solve backend and frontend problems, use AI coding tools responsibly, and keep growing with modern technologies.

At Touken, I led end-to-end TypeScript, React, and Node.js feature development, integrated production services, and implemented LLM-based workflow automation while resolving performance and critical production issues.

I've built full-stack e-commerce and inventory platforms for freelance clients, owning architecture through delivery. My work includes Mercado Pago payments and webhook security, JWT authentication, role-based access control, PostgreSQL, MySQL, MongoDB, Docker, and continuous deployment.
