Software studio · Mataró, Catalunya
I build software and apps
and understand the business behind them.
ATM DEV is a software development studio based in Mataró. I build apps and digital products end to end —from the backend to the App Store— along with the infrastructure that keeps them running.
How I work
AI as production infrastructure, not as an object of study. The stack is there to ship software, not to collect tools.
