ROUND
Anyone can make a bracket without signing up, and correcting a result never leaves past records and the next matches out of sync.
Products
Products I build and run, the engines and modules grown inside them, and projects built inside other companies' products.
Products I build
Services I plan, build, and operate myself.
Firstage
At Firstage, the company I founded, I plan, build, and run on my own a family of services led by Journey, which turns photos and places into a record of everyday life, along with the modules they share.
166Page layouts to choose from in the photobook editor, across 10 themes
- When you upload photos, the time and place they were taken connect, so scattered days are easy to find again and share with the people close to you.
- Original photos are saved first, and heavier work such as previews and reading where they were taken runs in the background
- A photobook editor where AI suggests the layout and fixed rules place everything the same way every time
- 10 photobook themes and 166 page layouts available
- Live on the web, with the iOS app in internal testing before release
Social publishing service
A product that put writing and scheduled posting for several social platforms on one screen, which I built alone over about six months to test the market.
6 monthsBuilt alone, from planning to payments and server operations
- Writing and scheduling posts for several social accounts on one screen cut out signing in to each platform to post.
- About six months of solo work, from planning to payments and server operations
- Instagram, Threads, Pinterest, and more connected on one screen
- Posts go out at the scheduled time, and platform sign-ins renew automatically
- After testing the market, the direction shifted to place-based records
Built inside other companies' products
Projects where I designed and built core flows inside other companies' products.
- 1-2Work cycles (sprints) to finish alone what took 3 to 4 people 2 to 3 cycles (tech lead's assessment)
ONE tech eCom
Only the country fields a route needs appear on screen, and server checks, storage, and printed documents follow the same conditions.
Fursys website and admin
The operations team now manages everything from product listings to documents, terms, and news without asking developers.
Yogiyo unified checkout
The Yogiyo app now handles very different order types, from robot delivery to dining in, through one checkout flow.
Allganize AI Messenger SDK
Each client's design and feature requests can now be met while the core code stays untouched.
Channel Talk team features and customer DB
Managers can now be grouped into teams, so one mention calls the whole team and a chat can go to a team, and operators no longer wait at the screen for a large download to finish.
- CJ ENM
CJ ENM event pages and page builder
Operators now open seasonal event pages themselves in the builder, where each season used to need a developer deploy.
- 99.8%Usage free of crashes, measured in Sentry, up from 96%
Volta micro frontends and design system
Volta can now ship and roll back only the part that changed, without rebuilding the whole service.
Engines and modules grown inside the products
Private packages I separated out while building products. I develop them in Storybook and use them in Firstage products.
kuery
Records are filtered exactly as the chips show, and a selection never widens the scope of an action.
canvas-builder
Pages hold together whether someone with no design training edits them or hands the job to AI.
i18n
Servers keep the language of the person on screen apart from the language of the person receiving a message, so a push notification about someone else reaches each recipient in their own language.
maps
Screens with a map never handle the map library directly; they pick only what they need, such as place clusters or routes.
grids
Sorting, filtering, and scrolling never change the selected rows, so bulk actions apply only to the records you picked.
chats
A product adding AI conversation only adds its own messages, such as edit proposal cards, without rebuilding live replies or scrolling.
Design system
Every app keeps the same accessibility standard while choosing its own color theme.
editors
New writing screens and other products don't build an editor of their own; they pick the features they need on the shared core.
Built to test an idea
Things I built to test a product idea or to support the work.
