Web3 marketing PM at DeSpread who got tired of repetitive work and started building the automation himself. Now I ship the dashboards, agents, and on-chain systems my team runs on.
- PM × developer. Led Korean marketing for major Web3 protocols, then turned the repetitive parts of the job into production software — and kept the pager.
- Full-stack + on-chain. TypeScript / Python / Solidity, from Next.js dashboards to Postgres data pipelines to EIP-712 reward vaults on mainnet.
- AI-native. Build agents, NL→SQL, multi-source RAG, and LLM extraction pipelines as everyday tools — not demos.
Most of these live in private org repos, so the numbers below are what tells the story.
Sole builder — 682 / 697 commits (98%). The internal tool a consulting team runs on.
- Slack slash-command bot (modal → DB → channel alerts, signature-verified)
- KOL settlement automation with a 6-step forwarding-tracker cron (4-hour state machine)
- Dual Supabase (read/write split), Claude Haiku for summarization & scoring
- ~50k LOC TypeScript · 64 API routes · 5 crons · 23 pages
Author of the core governance & tooling modules — 2nd overall committer.
- Org-wide governance agents: PR-review bot + secret scanner + git guardrail hooks
- Natural-language → SQL over a read-only warehouse via MCP
- Multi-source RAG research agent with style-learning and output guardrails
#1 committer — 863 / 3,042 commits (~28%) on a pnpm + Turborepo monorepo.
- Analyst-PDF → 8-figure LLM extraction (structured output + Zod, confidence + cost metering, multimodal OCR fallback)
- Real-time WebSocket quote client: exponential backoff, session-phase awareness, tick→candle merging, REST fallback
- Valuation engine: Piotroski F-Score, Altman Z, PER/PBR/EV-EBITDA, 4-factor radar
- Prisma 93 models on AWS RDS · Next.js RSC + React 19
- Honest scope: the AI-search RAG and the translator were teammates' work — not mine.
Sole author — 1,200+ commits.
- Telegram bot (python-telegram-bot), 50+ anti-spam patterns, impersonation detection, scheduled messaging
- On-chain reward vaults in Foundry / Solidity on Base & Arbitrum mainnet
- EIP-712 signed claims, cross-chain replay protection, daily limits + cooldowns, atomic locking
- dApp dashboard with wagmi / viem (Telegram mini-app wallet)
