ECE @ UW • Research @ PNNL • Builder
I'm Andrew Gui — an ECE undergrad at the University of Washington. I split my time between research at Pacific Northwest National Laboratory, where I work on SensorFish technology, and shipping software — most recently MyFitnessTech, an iOS app built with Flutter and Firebase. I also co-authored AI hardware research published at MICRO 2024.
I founded Fitness Tech at UW and box with the Husky Boxing Team. When I'm not building something, I'm training, wakeboarding, skiing, or finding the next thing worth learning.
A Registered Student Organization at the University of Washington bringing together students passionate about fitness, health tech, and innovation. We design hardware, ship software, and explore how technology can optimize training and wellness.
Analyzing autonomous SensorFish data to characterize fish passage conditions through dams. Building Python tools for data visualization, precision soldering sensor-to-computer connections, and contributing to a low head dam literature review paper.
Co-authored research optimizing Large Language Models through Logarithmic Number System implementations. Published at MICRO 2024.

Nov 2022 – Jun 2023
I just put the fries in the bag. Sometimes nuggets or even a burger.
What I build at Fitness Tech — the app, and the hardware that talks to it.
The official Fitness Tech app
An iOS fitness app built with Flutter and Firebase. Nutrition, training, steps and sleep roll up into one daily view, alongside social features and a device layer that pairs the club's own hardware straight into the app. Live on the App Store.
Smart bottle — Fitness Tech hardware
A water bottle that weighs every sip. A load cell reads the bottle and an IMU catches the tilt, but a sip only counts once the water settles and the weight actually drops — so bumps and set-downs don't register. A XIAO ESP32-C3 streams it over BLE into MyFitnessTech as live hydration: sips, ounces drank, ounces left.
