About me

I've spent 8 years solving real technical problems for companies and users, the last ones as Team Leader coordinating a support team. That experience taught me something tutorials don't: software exists for people, and those people need it to work well.

Now I bring that vision to iOS development. I write in Swift because I believe in doing it right, natively, with the tools Apple provides. I completed the Swift Developer Program with a functional final project as its capstone.

I'm looking for my first opportunity as an iOS developer, where I can bring both my code and my experience dealing with people and resolving incidents under pressure.
