Sunwoo Kim (๊น€์„ ์šฐ)

Fullstack engineer & CTO. 12 years. I ship products โ€” and I keep them running.

Building fast is table stakes now. Anyone can generate a screen. What I do is design the thing behind the screen so it doesn't fall over โ€” and then actually operate it.

  • ๐Ÿ—๏ธ CTO @ YAYLABS ยท Co-founder @ YayPlanet โ€” built Oildealer solo: escrow-backed B2B reverse-auction platform, 3 client apps (customer web+mobile, vendor, admin), live on both app stores, 5 microservices on Kubernetes
  • ๐Ÿค– I run my company AI-native. An in-house AI agent (Hermes) lives in Slack: it auto-tags documents into Notion, routes planning tickets to developers, and closes the loop โ€” deploy done โ†’ report back โ†’ ticket closed โ†’ patch notes generated. Slack is the whole company's single gateway. Now delivering the same AX (AI transformation) pipelines for external clients โ€” a hospital and an investment firm.
  • ๐ŸŽจ I build without designers. Not "AI-looking" UI โ€” I wrote a design system that teaches AI design judgment, and open-sourced it: styleseed GitHub stars โ€” 800+ organic stars, zero marketing, still climbing
  • ๐Ÿ“Š ML in production, not in notebooks โ€” LSTM price model at 0.74% MAPE, beat GARCH/VAR/XGBoost
  • โ›“๏ธ Web3 at scale โ€” RWA bond protocol ยท transaction forwarding API for 300K game users at 100+ TPS ยท Unity WebGL game shipped inside both Telegram and LINE mini-apps
  • ๐Ÿข Before this: eBay Korea (led legacy โ†’ React SPA migration), Samsung Card (Vue/Nuxt architecture)

What I actually do

Depth, not just breadth Led a legacy (JSP/jQuery/.NET) โ†’ React SPA migration on a live commerce platform. Page load โˆ’60%, DB load โˆ’40%. Nothing broke.
0โ†’1 with architecture Took a product from "we have an idea" to shipped MVP as a contractor โ€” auth, payments, points, raffle engine, community, admin.
AI-native operations Built the company's internal AI infra myself: a Slack-resident agent (Hermes) that tags & archives docs to Notion, generates status reports, and runs the ticket โ†’ dev โ†’ deploy โ†’ patch-note pipeline. Every employee works through Slack as the gateway. Now replicating this for client orgs (hospital ยท investment firm).
Design without a designer styleseed โ€” 74 design rules, 48 components, 7 brand skins. The tool I built to fix the UI that AI coding tools generate.
Infra that stays up Kubernetes, zero-downtime deploys, CI/CD, Saga-pattern event-driven orchestration. Running today, not a demo.
AI as a pipeline, not a demo Agent workflows that scan โ†’ analyze โ†’ render โ†’ package, with a human gate before publish.

Selected work

YAYLABS โ€” corporate website and brand experience

Live YAYLABS corporate homepage

I planned, designed, developed, and deployed the YAYLABS corporate website as an in-house project. I organized our products and AX services around what a prospective client needs to understand, then built an interactive brand experience with the original YAY CORE, project case studies, five service pages, and a clear inquiry path. The site is responsive, with reduced-motion and WebGL fallbacks; essential content and contact options remain available without the animation. Search-facing pages and FAQs are server-rendered, with matching metadata and structured data. This is our own company site, not a client commission.

Oildealer โ€” escrow-backed B2B reverse-auction platform (built solo, live on both stores)

Oildealer

CTO. Planning โ†’ architecture โ†’ development โ†’ design โ†’ operations. One person, end to end.

Everything a production service needs, in one project: reverse auction ยท escrow payments ยท community ยท ML price forecasting ยท monitoring ยท web ordering ยท customer app ยท vendor app ยท admin. 3 client apps built solo โ€” customer (web-only + app-only), vendor, admin โ€” shipped to both iOS/Android stores and operated since (review cycles, rejections, version rollouts included). 5 microservices (dual frontend / collection API / business backend / scheduler / admin) on Kubernetes, zero-downtime. MongoDB Time Series + Redis. Playwright-based market data pipeline. GPT-4o news agent with daily briefing. In-house LSTM price forecasting โ€” MAPE 0.74%, 88% directional accuracy, benchmarked against GARCH ยท VAR ยท VECM ยท XGBoost. Windows agent syncing POS + tank sensors on site. Zero designers on the project. Corporate site included: oildealer.co.kr โ€” blog-connected, all visual assets generated through an AI pipeline (Higgsfield).

Hermes โ€” AI-native company infrastructure (in production, daily)

Slack is the company's operating system โ€” not a metaphor, the actual daily workflow: a planner posts a request and the agent acknowledges it in-thread ยท documents get auto-tagged and archived into Notion ยท dev progress is reported at the level of ticket numbers, branch names and commit hashes ("verified in code", not "probably done") ยท the AI dev-session bot posts [in-progress] updates (PR merged โ†’ deploying โ†’ tests passing) and closes with [done] โ€” production live, patch notes auto-generated back to the planner ยท missing artifacts (deploy URL, QA results) are chased by the agent, not by humans. Channels are designed on purpose: planningโ†”dev handoff ยท product specs ยท ops ยท alert severity tiers ยท a dedicated channel per AX client. Humans keep the decisions; the agent keeps the state. Now shipping the same loop externally as AX (AI transformation) for two clients: a hospital โ€” marketing-intelligence pipeline on official Naver/YouTube APIs (keyword ยท ad-creative ยท content-trend collection with medical-ad compliance guardrails) plus an AI-citation back-tracking loop (trace which sources AI assistants cite โ†’ find gaps where competitors are cited and you aren't โ†’ prescribe content โ†’ re-measure) โ€” and an investment firm (internal operations AX).

HOLTZMAN โ€” hospital marketing AX platform and responsive landing

Live HOLTZMAN landing page with a metallic H visual and hospital marketing AX story

I planned, designed, built, and deployed the public landing page for YAYLABS' hospital marketing AX work. It takes a visitor from the hospital's operating problem through the data-to-action workflow, a field case, product screens, and a clear consultation path. The responsive page uses a distinct visual system, a large 3D H, and interactive examples; demo data is labeled and separated from real clinic accounts.

Behind the public story, I built the data and AI workflow for revenue and advertising analysis, keyword planning, content production, AI-search visibility checks, and readable reports for hospital operators. The landing and the internal console serve different audiences; the live link shows the public experience, not a customer account.

YieldCore โ€” on-chain RWA bond investment protocol

YieldCore

Solidity contracts (proxy & non-proxy variants) where investors deposit USDC against real-world bond deals โ€” deposit/withdraw hub, deal vaults, loan registry, P2P share marketplace. 24h timelock on loan execution, multisig, role separation. Next.js investor dashboard (TVL/APY, deals, portfolio) and a Node.js monitor watching on-chain events 24/7 with Slack alerts โ€” fund movements, pause events, payout reminders. Corporate site: yieldcorelabs.com โ€” English-first, Notion-backed content pipeline (non-devs edit in Notion, the site updates itself).

FANANAS โ€” Unity WebGL game on Telegram & LINE mini-apps

FANANAS

Solitaire-based Web3 game: Unity (C#) โ†’ WebGL build, shipped inside both Telegram and LINE mini-apps. Kotlin middleware bridging game score โ†” platform identity โ†” on-chain settlement. Running on Kubernetes. Mission & reward logic is a specialty: completion judgment โ†’ reward grant โ†’ conditional unlock, with probability tables externalized from code.

NNN โ€” Telegram ร— TON gamefi launchpad

NNN

Launchpad backend (Node/Express, layered), TON smart contracts, Telegram mini-app frontend, partner-game integration API. Probability-driven mystery box engine with externalized probability tables. Weekly reward distribution via cron, with recovery path on failed payouts. Partner games integrated in under a day.

Transaction forwarding API โ€” LINE ร— Kaia

Redis + message queue architecture that decouples transaction submission from service logic. Sidesteps nonce collisions and rate limits by queueing instead of hammering the chain. Retries, backoff, failure replay. 300K game users. 100+ TPS at peak.

Penguinboard โ€” multi-platform seller data SaaS

Penguinboard

B2B SaaS unifying seller data across 9 commerce platforms โ€” with a Chrome Extension (MV3) collection engine: XHR/Fetch interceptors, session keep-alive, verified live against real seller admin consoles.

OHTTO โ€” wish-based social commerce (contracted MVP, delivered)

OHTTO

Took it on with no plans and no designs; delivered a working MVP end to end as a contractor โ€” Kakao login, PG payments, points, live raffle engine, community, admin. The wish-ranking home above is the shipped product.

MARKET WHY โ€” AI narration video pipeline

Script โ†’ TTS (SSML-controlled) โ†’ scene timing auto-matched to the actual audio length โ†’ subtitles โ†’ thumbnail โ†’ publish package. The sync isn't eyeballed on a timeline; the voice length determines the scene length. Change the script, re-render, still in sync. Runs headless on a schedule. Publishing stays a human decision.

Mirirang โ€” AI-character-first fortune app

Mirirang

A fortune-telling app where the AI character speaks first โ€” planning, character design direction, and development in one hand.


Open source

styleseed GitHub stars โ€” Teach your AI design judgment. Not just components. Design system engine for Claude Code / Codex / Cursor. 74 rules, 48 components, 7 brand skins (Toss/Stripe/Linear/Notion/Raycast/Arc/Vercel), a named motion system. 800+ stars, all organic โ€” no launch post, no ads. MIT.

codesyncer โ€” Claude forgets everything when the session ends. CodeSyncer makes it remember. Multi-repo collaboration framework for AI coding agents. Decisions and inferences get recorded as @codesyncer-* tags instead of evaporating. On npm. Oildealer actually runs on it.

pixelmind โ€” Your LLM is blind to what it creates. We give it eyes. Render-aware feedback loop for LLM-generated UI.
