Backend Developer from Guatemala, focused on building reliable APIs, scalable services, and practical software solutions.
I mainly work with Java, Spring Boot, TypeScript, Node.js, and relational databases.
I enjoy designing backend systems with clear contracts, consistent error handling, and maintainable architecture.
My work is usually centered around turning business requirements into stable APIs, improving internal processes through automation, and reducing repeated code by creating reusable tools and shared patterns.

- Clean, maintainable, production-ready code
A reusable Spring Boot library for REST APIs.
It centralizes common backend patterns such as standardized responses, pagination, global error handling, search utilities, rate limiting, security handlers, and username validation.
The goal is simple: avoid repeating the same infrastructure code across multiple Spring Boot projects and keep APIs more consistent.
