As a freelance Full Stack Developer, I’m developing SGR-Turnos, a banking queue system with Symfony 8, JWT, rate limiting, auditing, and Excel export. I’m also developing ComercioLocal, a SaaS e-commerce platform with Stripe, OAuth2, 2FA, and Redis.

At Local Development Center, I developed and maintained web applications with Java, Spring Boot, PHP, and Symfony. I also worked on frontend development with HTML5, CSS3, JavaScript, and Tailwind.

My projects include Spring Boot microservices and Android applications for banking queues. I’m pursuing a Master’s in Applied Informatics focused on distributed architectures and high-concurrency systems, and I use AI agents with harness engineering in my development workflow.
