About Dario

I am a Software Engineer with over a decade of experience, specializing in PHP development with its two main frameworks, Symfony and Laravel. I have also worked extensively with Vue.js (Vue 2 and Vue 3), leveraging Nuxt and Quasar to build modern, efficient, and scalable front-end solutions.

Throughout my career, I have led the design, migration, and upgrading of custom projects, adapting to the unique needs and challenges of each client. I thrive on integrating new tools and architectures in multichannel environments, always aiming to modernize legacy systems and optimize performance.
