MORE ABOUT FREDDY
I am Freddy Arvizu, a senior full-stack developer with technical, visual and business judgment.
I build technology, but the work starts before code: understanding the problem, shaping the idea, defining the solution and building it on a reliable technical base. I can move across backend, frontend, integrations, automation, analytics, ecommerce and digital experience without losing sight of business operations.
Senior developer focused on software, web, integrations, automation and business digital solutions.
