Projects Log

A record of what I've built and run — live services, systems programming, and hackathon builds.

All projects

  • VirtualucidA self-hosted 3D community-world platform entered through a browser link. Go services and a Rust authoritative simulation own sessions, recovery, and world state.
  • Music Production OSA local-first music-production workstation connecting an AppKit UI and MCP to a Rust project core and C++23 real-time DSP engine.
  • Meetup LabRunning and attending a Private Meetup every four days since June 2024 — 200+ sessions and counting.
  • Creator Discovery CommunityA confidential community that discovers and ranks creators by live growth signal rather than follower count (service name masked).
  • Canonical Entity WarehouseA confidential data warehouse that unifies people/accounts/orgs across several projects into one canonical store — dedup + soft-delete governance, each project reading only its slice (scale/target masked).
  • ParentlyzeA parenting product that turns family conversations into structured insights and tailored reports — spanning iOS/Android apps, web/Admin/backend, an in-house STT/AI engine, and internal operations systems. Co-founded 2025-06, CTO.
  • Outreach CRMA local-first CRM that runs outreach with auto-generated messages and stage tracking — zero server infra.
  • Instagram Audience ManagerA local-first Chrome extension that snapshots and analyzes my Instagram audience like git — on-device, no backend.
  • What if…?Upload a chat export and simulate the parallel universe of "what if I'd said this instead" — built in one day at Cursor Hackathon Seoul.
  • openclaw Agent FleetA multi-agent orchestration system that runs AI agents across several machines around the clock. OpenClaw, Codex, Python, cron, and SSH coordinate distributed work, validation, and machine sync.
  • News Intelligence EngineA confidential news engine that collects global news across distributed nodes, dedupes and ranks it, and layers human verification over LLM judgment (name withheld).
  • Caption Logger for Google MeetA Chrome extension that logs and copies Google Meet captions locally without sending a single line off the device — zero dependencies, zero network calls.
  • TrueTwoA daily family game of two truths and one lie — built and shipped in a single day at the IndieCrew hackathon.
  • WorldClone LabA validation platform that, before launching a product, creates a virtual population of users and previews their reactions through simulation.
  • Recallink · Core & DocsNot a contacts app but a personal relationship CRM that remembers "what happened with this person." Web, app, and local DB all share the same model.
  • Recallink · Web (PWA)Recallink's web app that keeps running the same screens even when the internet drops. Logging in automatically merges with the cloud.
  • Recallink · Mobile (KMP)Recallink's Android/iOS apps. Core logic written once, with the UI built separately in each OS's native toolkit.
  • Cardly StudioA content tool that stamps out card news in one go using 13 trend presets and AI prompts instead of designing each one by hand.
  • AI Visual Studio PlatformA confidential media platform pivoting from AI image distribution to a premium AI virtual photoshoot studio (name withheld).
  • InveraA community platform for exam-takers and parents. Integrates school verification · feed · spaces · administrator operations.
  • Content Operations StudioA confidential multi-tenant content studio where a team stamps out card-news and short-form scenarios together (name withheld).
  • Stablecoin Payment GatewayA confidential non-custodial multi-chain payment gateway that settles stablecoins directly into merchant wallets (name withheld).
  • Multi-Broker Trading PlatformA confidential 3-tier multi-broker trading platform with a cloud dashboard, a local executor, and a Rust simulation engine (name withheld).
  • Potentivo Lab · 회사 페이지The official site that serves as the face of Potentivo Lab, the company I co-founded. I was personally responsible for Korean/English localization through to search and LLM visibility.
  • Yonsei Mileage ViewerA student tool that went viral for a season by showing mileage course-registration results faster than the school's official system.
  • UWB Autonomous CarrierA follow-me autonomous vehicle based on UWB trilateration. Mobile positioning with 2 ESP32s and 3 DWM3000s.
  • Data Reverse-Engineering R&DA confidential data-extraction R&D engagement carried out on contract — reverse-engineering numbers visually obfuscated by CSS classes to restore them (target/client masked).
  • Fjord EduBuilt a college-admissions academy's booking, payment, student workflow, and internal operations platform — handling over KRW 300 million in payments in a single day without downtime.
  • Liner × InsidersA short-term prototype for the Liner collaboration (5 days).
  • Cha-GoA small build — a 1-week solo prototype.
  • CardmaruA short-term card news content build (1 week).
  • SparkdateA 5-day dating-concept prototype.
  • Sky TalkA 1-day quick prototype.
  • Dream ChaserA web simulation game where you raise your own idol group in 20 days — built and deployed in one day at the KeYThon hackathon.
