About Carlos

Carlos Ferrer

Software Engineer, Founder & CEO.
I turn ideas into software.

I work from problem framing to production, connecting architecture, product, design, and business to build software that can evolve.

I am a lawyer by training, and it shows in how I work: close reading of business rules, structured reasoning, clear documentation, and well-grounded decisions.
