I work on machine learning. Here you'll also find old game engines, FPGA experiments, and a fruit fly running on a Game Boy Advance.
Python and PyTorch for ML; Rust and C/C++ for engines and native tools; Verilog and SystemVerilog for FPGA projects.

Original Nokia firmware running on an FPGA. An ARM7TDMI core and the phone’s own menus; boot reliability is still a work in progress.

- Effective LLM Alignment — training and alignment tools at VikhrModels: SFT, preference optimization, reward modeling, and distillation.
- openTPU on Tang Nano 20K — an openTPU ISA implementation for a small FPGA, with language model weights streamed from an SD card.
- openHT2 — rebuilding the runtime of Hard Truck 2 / Дальнобойщики 2 in Rust. File formats, rendering, and vehicle physics.
