About me
Engineering grounded in business reality.
I am a Full-Stack Software Developer from Argentina with more than 10 years of experience designing, developing and maintaining business-critical software.
Throughout my career, I have built SaaS platforms, point-of-sale systems, multi-branch applications, APIs, mobile apps and internal management tools. I enjoy understanding how a business operates and turning real operational problems into practical, maintainable software.
My core stack is PHP, Laravel, MySQL and JavaScript. I also use AI-assisted development to improve research, coding, debugging, testing and documentation while keeping human technical judgment at the center.
