Alex Rosano

Staff Software Engineer · AI Platform & Distributed Systems Architect

I've been building software since I was a kid. At Warner Bros. Discovery, I got to see projects through from start to finish, on products like Bleacher Report, NBA Digital, and March Madness Live. I like building apps and software that people use, and I thrive on user feedback.

As a leader, I believe in keeping things simple. Over the years, I've learned plenty of hard lessons, and they've shaped how I work with others. I value transparency, remove obstacles for my team, and focus on creating an environment where people can do their best work.

Outside of work, I enjoy making things with my hands. Whether I'm tinkering with hardware or woodworking. I'm happiest when I'm building something.
