About
Son, Husband and a Friend
Before anything else, I’m a son, a husband, and a friend. These are the roles that mean the most to me, even if I don’t always get everything right.
I’m someone who’s still figuring things out, learning as I go, and trying to become a little better than I was yesterday. I care about the people around me, the promises I make, and the kind of person I become along the way. I believe being there for someone matters more than having the perfect words to say.
Professionally, I’m a software engineer who enjoys building things, solving problems, and understanding how things work. Over the years, I’ve found myself moving beyond writing code into making product decisions, leading teams, and figuring out how to turn ideas into something useful. Lately, I’ve been spending a lot of time exploring AI and building products of my own. There’s something deeply satisfying about starting with an idea and slowly bringing it to life.
At the end of the day, I hope I build good things, do right by the people I love, and leave a little good behind wherever life takes me.
