About

I am David Daniel Delgado González, a web developer in Panama City. I completed a Bachiller en Tecnología Informática (IT diploma) in 2022, and since 23 March 2026 I study Software Development and Management at the Technological University of Panama.

Since June 2023 I have worked at INVENTARIO S.A., a design and software agency in the World Target Group. I started on a professional services contract and have been on a permanent contract since January 2026. In those years I have delivered 23 projects: four APIs in production, twelve sites, three applications and three WordPress or Shopify themes and plugins.

Engineering Practices

Counted across the repos above, at their real scope. Each one is verifiable in the code.

Authentication
JWT with bcrypt hashing in three of the four APIs, and token rotation with refresh tokens in two.
Validation and file uploads
Zod schemas in the Fastify API; Multer with storage in the three APIs that accept files.
Network and headers
CORS configured in all four APIs, and security headers in the hotel signage one.
Accessibility
Semantic HTML and ARIA attributes in 17 of the 23 repos; prefers-reduced-motion respected wherever there is animation.
Documentation
Change logs in 10 of the 23 repos, and environment variables always shipped with an example file.
Internationalization
Content and routes kept separate in Spanish and English, in 10 of the 23 repos.
