Hi, I'm Tristan Seifert.


About Me

I'm an expert C/C++ developer, specializing in systems/embedded applications. I'm familiar with embedded development on ARM, x86/x86_64, and PowerPC. I also have experience using PHP and Python both on the web and to build tools.

Additionally, I'm familiar with the macOS Cocoa, iOS CocoaTouch APIs using Objective-C and Swift.

I design and build hardware in my spare time, and have experience with AVR, PIC and ARM (primarily STM32) microcontrollers, designing around bare ARM SoCs, as well as Xilinx and Intel FPGAs. I'm a recent KiCAD convert.


I currently work at Microsoft as a security software engineer.

Previously, I worked at Apple, Groupon, and Texas A&M University's Division of Marketing & Communications.

Older Projects

Here are some of my older projects, archived here for posterity: CardboardKit (MHacks 2015).

I have loads more projects that didn't quite make the cut (and/or are even less finished…) to be listed above. Check out my blog or GitHub profile to see what else I'm working on.


Have questions, or just want to chat? Email and I'll get back to you as soon as possible.

Usually, I will try to respond to emails within a week.
