About

I am a Senior Full Stack Developer with 13+ years of experience in Information Technology, combining software development, backend and frontend engineering, and IT infrastructure. I specialize in building scalable web applications, REST APIs, and e-commerce solutions, with strong expertise in PHP, JavaScript, and Python, as well as hands-on experience with modern frameworks and development practices.
