I build production full-stack web applications with React, Node.js, Shopify, and AI-assisted development.
HondurasWhat I'm looking for
I've built production web applications and internal tools across React, Next.js, TypeScript, NestJS, PostgreSQL, Angular, and Express. My work includes an inventory platform with JWT authentication, role-based access control, i18n, and CI/CD, plus e-commerce and medical scheduling projects.
For a Shopify client, I build reusable Liquid and Tailwind components from Figma designs, integrate the Admin GraphQL API, and automate data workflows with rollback logic and structured logging. At Agrega and OlanchoNet, I improved system visibility by 30%, reduced downtime by 20%, and supported cloud operations, incident management, and network monitoring.
