Wesley LongsdorfSoftware Engineer

Full-stack and embedded engineer who moves fluidly between the browser and bare metal. I ship polished, accessible web apps in TypeScript and obsess over the same rigor when writing safety-critical firmware for avionics.

04 — About

I'm an engineer who never picked a side. By day I build accessible, high-performance web apps in TypeScript, React, Next.js, and Angular. By night — and sometimes by day — I write safety-critical embedded software for systems that simply cannot fail.

That range shapes how I work: the discipline of DO-178C and ARINC 653 makes my web code more rigorous, and the fluidity of the web keeps my firmware tooling humane. Between them sits the thing I love most — the details. Especially the CSS.

I care about the space between elements, the easing on a transition, and the exact moment an interface feels alive. This whole site is hand-tuned to prove it.
