I build the side of the platform that earns.█

2.3 → 5.8%

Registration-to-deposit conversion, ×2.5 in six months

On any earning platform the most sensitive surface is where the money moves. I rebuilt signup and KYC, expanded the payment provider network, and made every payment observable — so routing decisions run on data, not incidents.

• Rebuilt the signup → KYC → deposit funnel: removed steps, parallelized checks — verification conversion nearly doubled, 10.6% → 19.2%.
• Launched 4 payment provider integrations, widening method coverage and cutting single-provider dependency.
• Built provider-level observability across 10 providers: success rates, failure reasons, volumes and profitability on one dashboard.

Iteration cycle — hypotheses validated 3× faster

Owned product across BADMAD ROBOTS and the surrounding gaming ecosystem. Alongside the game, we built acid.market — an NFT marketplace on Immutable designed for BADMAD ROBOTS and other games. The game reached 120K+ pre-launch signups through community-led development.

• Cut the iteration cycle 3× with focused sprints and automated QA pipelines — speed became the product strategy.
• Built the analytics framework (Amplitude + custom SQL) that found retention-predicting behaviors; killed 40% of low-value backlog, beta satisfaction 3.8 → 4.3.
• Built acid.market as a multi-game marketplace on Immutable — extending the product beyond a single title into discovery and transactions for in-game digital assets.

Partner activation time, after replacing manual onboarding with self-service

I owned the supply side of one of the world's biggest gaming platforms: the studios and developers whose revenue depends on how easy we are to build on. Same logic as streamers on a creator platform — their success is the ecosystem's growth.

• Shipped a self-service partner portal that turned weeks of email threads into a guided flow. Partner NPS rose 18 points.
• Built a cross-regional feedback system: 200+ partner issues captured, triaged, and driven into the roadmap of two major platform releases.
• Led GTM for 10+ launches; the top 3 beat Week-1 revenue targets by 35% on average.

Users from MVP in 24 months · 7-day retention 22% → 41%

A mobile video platform where K-pop stars ran a real business: every artist had a back office to set up streams, merch and monetization. I owned the product end to end — and the growth came from the creator side.

• Shipped 12 major features — live streaming, digital marketplace, creator tools — prioritized through interviews with artists and their management.
• Ran 50+ A/B tests on onboarding, personalization and notification timing; monthly churn fell 63%.
• Launched in Korea and Japan — localized the product experience around local fan behavior, content and monetization.
