About

Alex Grzelewski

I'm a Mathematics major with an Engineering minor at Texas Tech University, graduating in May 2027. I like understanding how things work from the hardware up, and I build things to learn them.

Outside of class I restore and run old server hardware, design my own circuit boards, work through number theory for fun, and host my own file sharing service. Those projects are below, and I'm happy to talk through any of them.

  • Python · Java · Kotlin
  • Linux · Git
  • KiCAD · SolidWorks · MATLAB

Things I work on

Four projects, each with its own write-up.

01

Setting up old hardware

Getting server-grade and end-of-life machines running again: NVIDIA V100s, Supermicro X99 boards, and other finds from Xianyu and eBay.

Math for my own research

Self-directed number theory. I'm learning how the Quadratic Sieve works by building my own implementation of it.

  • Number theory
  • Factoring
  • Algorithms
