Hello World 👋 I'm Jesús Mendoza
I'm a FullStack Software Engineer with a strong focus on Frontend development and 7+ years of experience building web applications, REST APIs, desktop software, and cloud-based services.
My main frontend stack is React, TypeScript, JavaScript, and Next.js, complemented by professional backend experience with Java, Spring Boot, Spring MVC, Node.js, Express, Laravel, PHP, and Prisma.
I also enjoy working close to the infrastructure layer, including Google Cloud Platform, Linux, Nginx, PM2, Docker, CI/CD, and production deployments.
More recently, I've been incorporating AI-assisted development into my workflow using tools such as OpenCode, Claude Code, and Antigravity.
