About

I don’t use LinkedIn, so this page is a simple stand-in so you can see who I am and what I spend my time working on.

I’m an electrical engineering student focused on power electronics and embedded systems. Most of what I know comes from building things and then figuring out why they don’t behave the way I expected.

I first got into systems work building Intel Hackintosh machines, which is where I started learning how hardware and software interact at a low level.

A lot of my time goes into my homelab, where I run a mix of storage, compute, and GPU workloads. It started as a simple storage system and gradually grew as I added more services and complexity. These days the storage side is fairly straightforward, and most of the interesting work happens on high-memory machines I use as scratch space for running code and inference workloads. I’ve spent a lot of time chasing issues that only show up under load across networking, storage, and hardware and software boundaries. That process has taught me to stick with problems until I understand what is actually happening.

I also spend a lot of time working with microcontrollers, mostly STM32 and ESP. I like building small systems that interact with the physical world by reading sensors, controlling things, and tying that into larger systems. A lot of that work ends up being about integration, getting firmware, hardware, and infrastructure to work together reliably.

On the hardware side, I’ve done a fair amount of board-level work, including reworking QFN packages, tracking down faults, and fixing issues in power delivery sections and embedded boards. I enjoy that kind of debugging because it forces you to understand what the system is actually doing instead of what it is supposed to be doing.

I also design and 3D print parts when I need them, usually to support other projects such as mounting components, building enclosures, or solving mechanical constraints.

Separately, I built a browser-based fantasy football drafting tool called Legendary Upside Sidekick along with the backend that supports it. It is now used by a few hundred paying users. That project taught me a lot about taking something from an idea to a system that people actually rely on.

Most of what I work on is driven by curiosity. If something seems interesting or confusing, I usually end up building something around it just to understand it better.

You can find my GitHub here: github.com/lukesau. Most of my current work is in private repositories, but I would be happy to walk through specific projects in more detail in an interview.
