Product engineer based in Seoul.
Hawoon Joh ์กฐํ์ด ยท Product Engineer โ frontend, platform, and everything between
I build products end to end. That started as frontend work โ Next.js and TypeScript โ and kept expanding, because the interesting problems never stayed in one layer. Today that means leading a small engineering team, planning a product line, and owning the pipeline that ships it.
Spatial design to production infrastructure, one self-taught step at a time.
2020 ยท Kookmin University
Four years spent thinking about how people move through a space and what makes a layout legible. It turns out to be the same question a UI asks, which is why the switch felt less like a career change than a change of material.
2020โ21 ยท Design work
Working alongside software without being able to build it got old fast. I wanted to be the one shipping the thing, not handing off a file and hoping.
2021 ยท Bootcamp
I learned the server side before the client side. Backwards, by portfolio standards โ but knowing what a query costs and how a schema is shaped has been quietly useful in every frontend decision since.
2021โ22 ยท Self-taught
React, then Next.js and TypeScript, built by making things that had to actually work. No course completion certificate โ just a pile of projects, each one harder than the last.
2022 ยท CloudHospital
Joined to build the frontend and ended up responsible for the platform around it โ the marketing site and CMS, SEO, performance, and eventually the deployment pipeline. Now leading a team of four to eight.
Now ยท SynolinkCurrent
Product owner for synolink.ai โ three products, one modular suite. The largest thing I have been responsible for, and the first where I get to set the direction.
Every step, I taught myself the next thing the work needed.
How I work.
A page nobody can find and nobody waits for does not exist. Both belong in the plan, not the backlog.
Visual editors, code generation, automated pipelines. If a task will happen a hundred times, the second time should already be cheaper.
A demo that works once proves nothing. The details are where a prototype becomes a product.
Products I have built and led.
At CloudHospital I own the frontend of icloudhospital.com and its backoffice, plus the marketing site and the CMS behind it. Building it was the first half of the job.

Led client development
Omnichannel messaging
Customer conversations from every channel in one inbox.
Product planning as PO โ not hands-on development
Medical EHR
An electronic health record platform, built to slot into the same suite rather than sit off to the side as a silo.

From personal project to the core of Synolink CMS
It started as a personal project and became the core of the cms.synolink.ai editor, the visual web builder in the Synolink suite.
