Crushing on Jonathan Kelley
Yo, you gotta hear about Jonathan Kelley. This guy’s the real deal. He’s a YC S23 founder and CEO of Dioxus Labs, but get this-he’s been crushing it way before that. Started out as a college side project, right? Just tinkering in his free time, and now he’s got major orgs like Airbus, ESA, and Huawei using his stuff. No cap.
So, what’s Dioxus? It’s this open-source Rust library for cross-platform app dev. Basically, write your app once, and boom-you can use it everywhere. That’s a big change in the dev world. And the crazy part? Kelley built this from scratch, just because he saw a problem, and now it’s the go-to for some of the biggest names out there. That shows he’s got that startup hustle-spotting problems, building solutions, and then just crushing it.
But it’s not like he just fell into this. His background is deep in hardcore engineering and physics. He’s worked at Cloudflare-big name-interned at NASA, and did plasma physics research. So he’s not just some coder; he’s got that solid scientific mind and a passion for open source. That’s what makes him super interesting-dude’s all about building stuff that’s elegant, useful, and expandable.
