Zombie Destroyer
A roguelite survival-action where you hold back endless zombie hordes with weapons and relics. 241 skill nodes and relic combinations make every run a different build, and prestige carries growth across runs.

TEUM
A shared calendar for couples and small groups, synced across web, desktop, and Android from one codebase. Each group has its own room and calendar, and events can be shared into several groups at once. The newest piece: an admin-assigned shift roster with peer swaps, five days into an MVP with several features working.

SteamAchieve
A Windows app that puts your Steam achievement progress on one screen. There is no server: the API key you type never leaves the PC. It is the only thing I have built that I actually handed to other people, and what they said came back as the next version.

AI-Driven Producer · Planner
Hi, I buildgames & apps with AI as a producer.
I plan and build games, apps and pages in collaboration with AI. Rather than writing the code myself, I carry a project from the first idea through system design, AI-driven implementation and launch.

What I do
Planning
I write game and app design docs (GDD), from requirements to screen design.
Systems & data design
I design JSON data models and schemas, and handle balancing and content data.
AI collaboration
I design prompts, direct AI to implement, and review what it delivers.

Things I planned and built
Games, programs, apps and web pages, grouped by category.
Games
Zombie Destroyer
A roguelite survival-action where you hold back endless zombie hordes with weapons and relics. 241 skill nodes and relic combinations make every run a different build, and prestige carries growth across runs.
Torch & Tomb
A cursor-mining incremental: hover over crates, jars and wandering monsters and they shatter before your torch burns out. Spend the haul on a sprawling skill tree to open deeper dungeons. Eight days into development, a prototype with only a demo build (dungeons 1-3) public so far.
Frontier Domain
An idle merge tycoon: choose what to build and what to merge on a cramped domain, and the mercenaries go out and fight on their own. The design was thrown out and restarted in August 2026.
Basket
A first-person tidying game. Pick up the balls scattered across a room, throw them into the hoop, and watch the space empty out. No timer, no fail state. Just the chain reaction of a missed shot scattering everything again. Design is laid out and a movement prototype is in place.
Minesweeper
Minesweeper that does not end with one board. Boards keep joining on, a cascade spills across the seam into the next one, and coins unlock the boards ahead, including gold and boss ones.
Hexa Sort
A casual puzzle where you stack, merge and sort same-colored tiles on a hex board. Built on a single Capacitor web codebase, with Android wired up first and iOS the intended next target from the same source.
One Color
A color-perception puzzle. Spot and tap the one shape whose color differs ever so slightly. The gap narrows as difficulty climbs, leading into a time-attack mode played against a heart counter. An Android release bundle is already built.
Chill
An idle collection game. Set a trap, step away, and come back to find one more entry filled in your codex. Roam forest, cave, lake and snowfield, meeting one creature at a time. Design is complete; implementation is at an early stage.
Programs
snstool
A SNS operations tool where you register any product (app, game, website, whatever) as a profile, and AI drafts Instagram/Threads posts and comment-reply candidates from that material, though nothing goes out until a person approves it. Built generic from the start: adding another product is just another profile, no code change. Started September 2026, still in progress.
FakeClients
A desktop app where AI plays the client: it drops a brief that matches conditions you set, negotiates changes over chat, and scores whatever you submit. I built it because portfolio practice needs the feel of a real client and I did not have one. 12 days in, so this is a running MVP, not a finished product.
SteamAchieve
A Windows app that puts your Steam achievement progress on one screen. There is no server: the API key you type never leaves the PC. It is the only thing I have built that I actually handed to other people, and what they said came back as the next version.
Mailer
A desktop app that gathers several mail accounts onto one screen and sorts what can be ignored from what cannot. Rules classify first; a correction I make becomes a rule for that sender and is applied retroactively to mail already fetched. There is no server, and nothing is ever deleted permanently.
GDD Editor
Writing a game design document in raw HTML meant digging through tags to fix a single sentence. So I built a tool that edits the finished page itself. The messy HTML a browser produces never reaches the file. On every save a Python engine re-renders the document to a fixed set of rules.
CashCow
A local pipeline that tests, statistically, whether corporate disclosures (DART, SEC) move a stock within the same day. Collection, measurement, backtesting and adjudication live in one app, and the pass criteria were frozen before any result was seen. The finding so far is "no verified edge", and protecting that finding is the project's design goal.
OffNote
A meeting-notes app that transcribes and summarises entirely on your own PC, never uploading the recording. Capture, playback and the UI work; the recognition engine is still a mock. What exists so far is less the app than the decision in front of it: which model, at which settings, chosen by measurement.
Blogtool
A desktop hub for running several blogs side by side. Topic suggestion, drafting, fact-checking, image sourcing, machine checks and Tistory publishing all run from one button; only the last click stays with me. Fact-checking reads authoritative sources in full and records why a source could not be read when it cannot.
Apps
Yeogigo
A fully offline organizer that records where you put things, by photo, location and category, and finds them instantly. No account, server or ads. All data stays on your device.
Saju
A fully offline mobile app that reads your Four Pillars, five elements and fortune from your birth date. The lunar-calendar math and the readings all run on-device, with no server.
TEUM
A shared calendar for couples and small groups, synced across web, desktop, and Android from one codebase. Each group has its own room and calendar, and events can be shared into several groups at once. The newest piece: an admin-assigned shift roster with peer swaps, five days into an MVP with several features working.
SecondBrain
A minimal memo app that starts from the index card. No deep folder trees, just Category then Memo, two levels, to capture and recall ideas fast. Notes live only on the device, and no account is needed.
Web
Winsting Portfolio Website
The site you are looking at. Works live in Firestore and are edited from an admin screen; the build bakes them into static pages, and visitors see the latest without a redeploy.
Calqu (calqu.kr)
A Korean all-in-one tool portal: 186 tools across 15 categories, from take-home pay, tax and unit conversion calculators to character counters, QR and image utilities, mini-games and personality tests. Results can be saved as a PDF or embedded as a widget, and the tool list is also published as an llms.txt file.
