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, write GPU-accelerated search tools, 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 I build and run.

01

Setting up old hardware

Getting server-grade and end-of-life machines running again: NVIDIA V100s, Supermicro X9 boards, and other finds from Xianyu and eBay.

  • GPUs
  • Linux

Designing my own PCBs

Custom boards designed in KiCAD, including a PCIe to SFF-8654 adapter for connecting multiple GPUs.

Balatro seed searcher

GPU-accelerated seed searcher written in Kotlin with OpenCL kernels. Search conditions are defined in code and evaluated across the seed space in parallel using FP64 vector operations, reaching up to ~5 billion seeds/sec on multi-ante conditions with data center GPUs.

  • Kotlin
  • OpenCL
  • GPU compute
