About

Four focused foundations — and the operating systems that make them repeatable.

Organic Growth

Wishlist, retention, and revenue moved by community engagement — paid marketing is in the toolkit, but community-led organic growth is the edge.

Launch & Platform

Steam, Microsoft Store, PS5 setup, Switch 2 prep, multi-region GTM. Getting titles ready and live across the platforms players actually use.

Systems & AI Operations

29-language AI localization, KPI dashboards, admin and support tools. Built in-house so the team decides faster and operates at scale.

Live Service

Stable, fair operation grounded in anti-cheat and service-ops experience — the kind of trust players feel and come back for.

The Midnight Walkers

Business Director · Oneway Ticket Studio

2025 — Present · PC · PlayStation 5

▸ Challenge: Declining community momentum, weak conversion flow, and a 6-month window to scale wishlist into a global Early Access launch.

Eternal Return

Project Manager · Kakao Games Europe

2021 — 2025 · PC · Console

▸ Challenge: Western publishing for a Korean battle-royale × sub-culture title — low dev-side priority for the region, a fragmented community, and design directions conflicting with the main solo mode that made balance tuning difficult and user frustration persistent.
▸ What I changed: Built a data-driven focus strategy grounded in player + market data, rolled out grassroots esports, creator partnerships, and community programs. Pre-validated the team-mode transition through data analysis, and added Tableau KPI dashboards plus AI/LLM localization to accelerate operations.
▸ Result: 4× launch traffic, 210% of revenue target, +300% community participation, +25% ranked play — and a Western operating model that could be reused across the organization.
