What defines me
-
First, I understand your business.
Before writing any code, I meet with you to learn how you work today. The system adapts to your business, not the other way round.
-
You deal directly with the person who writes the code.
I design, build and deploy it myself. I handle your questions personally and explain each decision clearly.
-
After delivery, I stay with you.
I hand over a working system and train your team to use it. If something fails, I answer personally.

About me
I’m Adrián, an IT engineer. I adapt to what each client needs and see their ideas through.
Every business works its own way, so I don’t arrive with a ready-made solution. I listen, propose and adjust until the system fits the way its users actually work.
I have built very different systems: electronic invoicing, bookings with payments, offline inventory and a passenger counter that runs on computer vision. For each one I chose the technology that best solved the problem.
