Wyatt Hansen

I'm an Embedded Software Engineer at Accelsius in Austin, with a bachelor's in Computer Engineering from Texas A&M University, currently pursuing a Master of Science in Software Engineering at The University of Texas at Austin. I specialize in the end-to-end design of high-performance embedded systems — from STM32 firmware to embedded Linux services — and my graduate work focuses on software design, distributed systems, and applied machine learning. Most recently I designed and launched countriesofthe.world, a real-time multiplayer geography game built by directing AI coding agents end to end. I love building things — from soldering and 3D printing to shipping production software — that make a positive impact on the world.

Countries of the World Game

React TypeScript WebGL2 Node Postgres SSE AI-Directed (Claude Code)
Designed and launched a multiplayer geography game where players race the clock to type or find all 197 countries on an ASCII-art world map, featuring eight game modes across the modern world, five historical eras, Pangaea, and the US states. I developed this project entirely by directing AI coding agents (Claude Code): I owned the product direction, specified the features and gameplay rules, made the architecture decisions, reviewed the generated code, and tested every release on real desktop and mobile devices. The game runs on React and TypeScript with a WebGL2 map renderer, and a Hono and Node backend handling real-time multiplayer over Server-Sent Events, worldwide Postgres leaderboards, and anti-cheat telemetry. Deployed and operated in production on DigitalOcean behind Cloudflare. Check it out and play a game at countriesofthe.world!

Composition Helper

PyTorch DINOv3 Computer Vision ONNX Runtime Web WebGPU Progressive Web App
A collaborative research project on composition-aware aesthetic assessment, built on the Composition Assessment DataBase (CADB). We reproduced the SAMP-Net baseline and compared three DINOv3 architectures predicting the same five-bin quality distribution; the partially unfrozen backbone improved MSE, SRCC, and LCC over the baseline with EMD parity. The project also includes an on-device demo: a progressive web app that runs the fine-tuned model entirely on an iPhone through ONNX Runtime Web on WebGPU, scoring a photo in about 190 ms with no server and no network after the first load. It shows a 1-5 composition score, a percentile against the model's own CADB predictions, and ranked probabilities for all 14 composition techniques, drawing each technique's guide over the photo.

STM32 Robotic Arm Project

STM32 ADC I2C Servo Control 3D Printing
3D Printed Robotic Arm with a STM32 micro-controller, integrating a smaller robot as the primary controller using a Super Loop Control methodology. Using STM32 HAL, I mapped the readings of the Potentiometers using the ADC Peripheral to control the servos through a Servo Driver with I2C communication. Credits: YouTube Channel 'Build Some Stuff' - Robotic Arm Design and STL files for 3D Printing, Github User 'Lamik' - PCA9685 Servo Driver for STM32. Check out the code on my GitHub!

Embedded Linux STM32 C/C++ BACnet / Modbus / SNMP Firmware Tooling Product Demos
As an Embedded Software Engineer at Accelsius (May 2024 – Present, Embedded Software Engineer II since April 2026), I design and deploy embedded Linux services and STM32 firmware applications for two-phase direct-to-chip liquid cooling systems that keep AI and HPC data centers running. I own the customer-facing communication stacks — BACnet, Modbus, and SNMP — that integrate our systems with building-management and monitoring software, and I developed 'Snapshot', a fault-triggered flight recorder that captures every sensor and fault data point around a fault for retrospective root-cause analysis. I have also led over 50 live product demonstrations across three product lines, translating complex embedded architectures for customers and executive stakeholders.
