About

Professional summary

I am a Senior Fullstack and Backend Developer with more than 15 years of experience building robust web applications, scalable APIs, enterprise systems, and high-performance e-commerce platforms.

I specialize in the modern PHP ecosystem, particularly Laravel and Symfony, and I build reactive frontend applications with Vue.js and JavaScript. My work covers both monolithic and decoupled architectures.

I have extensive experience designing RESTful integrations, optimizing relational databases, implementing asynchronous job queues, and improving application reliability under high traffic conditions.

I combine software development expertise with DevOps and Linux system administration skills. I configure, secure, and maintain cloud and server environments using AWS, Google Cloud Platform, Nginx, Apache, Ubuntu, and CentOS.

I have delivered projects for private companies, public administration entities, universities, and e-commerce businesses. I focus on secure deployments, performance tuning, technical SEO, workflow automation, and maintainable code.
