My Why
From 'Freelancer' to 'Digital Partner'
SanahujaDev was born from a frustration you surely know: the 'abandoned website'. I saw friends and local businesses spend thousands on slow, buggy sites, whose developers (freelancers) vanished after delivery.
My brand was built as the antithesis of that. I don't sell a 'product' and leave. I provide a service and I stay. My 'Digital Partner' model is based on 12-month support. Because, as I always say, your success is my success.
