About me

I'm at my best when the problem is new and I don't know the answer yet.

I'm a Software Engineer driven by curiosity. Hand me a technology I've never touched and I won't stop at how to use it. I want to understand how it works. I don't give up easily either: when something breaks or gets hard, that's usually when I get more interested, not less. I'd rather take on something new and challenging than stay in my comfort zone, and I keep learning until it works.
