01 / THE PERSON BEHIND THE PIXELS
Who am I?
An engineer’s mind.
A researcher’s curiosity.
I’m Eddie (Junyoung Sohn), a product engineer building web and mobile products and developer tools. I’m an M.S. student in Computer Science at Yonsei University’s Mobile AI and Systems Lab, interested in on-device AI and systems.
The longer version
My product work spans TypeScript, React, Next.js, React Native, and workflow automation. I also build Python developer tools and study systems through C and Unix projects. I develop PALAIT through Nanocraft, finding research questions in the behavior and constraints of software people use.

02 / SELECTED WORK
Things I’m building.
Web products, open-source tools, and a personal prototype. Each project includes my focus and its current stage.

Posely
A webcam-based posture-sensing prototype using local inference. A practical setting for questions about continuous vision and resource use.
Project page · Posely ↗03 / QUESTIONS WORTH ASKING
A little deeper.
I’m an M.S. student in Computer Science at Yonsei University’s Mobile AI and Systems Lab (MAIS), advised by Professor Seonghoon Park. My interests include on-device AI, inference latency, and resource use in continuously running applications.
01
On-device AI
Intelligent applications that run on the devices we use every day.
02
Runtime behavior
Learning about latency and resource constraints in continuously running applications.
03
Questions from building
Connecting independent prototype work to questions worth investigating.
Independent projects are presented separately from my lab affiliation. Research outputs and publications will be added when ready to share.

04 / A FEW THINGS I CARE ABOUT
How I think
about the work.
Useful before impressive.
Start with a real need. Let the complexity earn its place.
Details are the experience.
A clear sentence, a considered interaction, a system that behaves as expected.
Stay curious. Stay honest.
Ask better questions. Make the evidence visible. Leave room to change your mind.
05 / THE JOURNEY
Always a
work in progress.

Good things start
with a hello.
A question, an idea, or a different way of looking at things.
I’d love to hear it.
