Judgment & Oversight

Every AI output goes through human review. Direction, final call, and taste stay with me.

Context Framing

Dedicated instruction files brief each agent on its role, constraints, and memory before every session.

Task Decomposition

Every delegated task is structured with goal, scope, constraints, and done criteria — written before the agent sees it.

Multi-Agent Orchestration

Claude, Codex, and Gemini assigned by task type and quota, running concurrently on one project.

Observability

Every agent action logged in real time. Task queue persists across sessions with full status tracking.

Adaptability

Switched models and toolchains multiple times as the AI landscape evolved — without losing momentum.

전략

Strategy

사업 구조와 방향을 재정의하는 판단 체계 — 시장 변화와 내부 역량을 함께 읽어 피벗 시점과 방향을 결정합니다.

01

수직 통합 피벗 설계

밸류체인 분석을 통해 외주 의존 구간을 내재화하는 방향으로 사업 구조를 재편했다

02

타겟 시장 재정의

피벗 과정에서 기존 고객군의 한계를 진단하고 집중할 세그먼트와 포지션을 새로 설정했다

03

사업 가설 & 중단 기준 설정

PoC마다 검증 지표와 중단 기준을 사전에 명시해 매몰 비용을 통제했다

재무

Finance

회계·세무·자금을 직접 다루는 재무 실무 — 세금 신고부터 투자 검토까지 숫자로 의사결정을 뒷받침합니다.

01

세무 신고 & 절세 설계

법인세·부가세·원천세를 직접 신고하고 절세 구조를 사전에 설계한다

02

자금 계획 & 운전자본 관리

월별 현금흐름을 예측하고 운전자본 부족이 발생하기 전 선제적으로 대응한다

03

투자 검토 & 밸류에이션

사업 기회를 수익성과 리스크 기준으로 평가하고 투자 여부를 판단한다

마케팅

Marketing

유입·전환·재방문을 잇는 실무 실행 체계 — ICP 식별부터 콘텐츠 자동화까지 데이터 기반으로 운영합니다.

01

ICP 식별 & 스코어링

Clay 데이터 보강으로 이상 고객 프로필을 정의하고 우선순위를 산정한다

02

콘텐츠 자동화 파이프라인

스크립트 생성·TTS·업로드를 자동화해 발행 주기를 단축하고 일관성을 유지한다

03

결과 중심 카피

기능 중심에서 결정 장면 중심 메시지로 전환해 전환율을 높인다

운영

Operations

사람·공간·프로세스를 조율하는 실행 기반 — 채용부터 설비까지 반복 가능한 운영 구조를 설계합니다.

01

채용 & 온보딩 설계

JD 작성·면접 기준·온보딩 체크리스트를 구조화해 초기 적응 비용을 줄인다

02

공간 & 설비 관리

사무 환경·장비·자산을 체계적으로 관리하고 운영 비용을 최적화한다

03

운영 SOP 표준화

핵심 반복 업무의 절차와 품질 기준을 문서화해 담당자 의존도를 낮춘다

Philosophy

Think in systems,
create in layers.

Strategic designer and systems builder at the intersection of business thinking, creative craft, and AI-powered operations. I build frameworks that connect analysis to execution — across disciplines, not within one.

Currently

01

Evolved the orchestration system into a full MCP server ecosystem — codex-mcp and gemini-mcp wrap the CLI agents as callable tools, available to any MCP client (Claude Code, Cursor, Windsurf)

02

Building a Korean compliance stack — law-mcp and nikl-mcp servers for legal registry access and standard dictionary validation, integrated into the AI writing pipeline

03

Developing an AI-powered Korean tax calculation engine — income tax, capital gains, and withholding rules encoded as a testable Python agent with Codex as the implementation worker
