Mobile App User Acquisition Manager at MEGARAMA GAMES, reaching 100% ROAS by day 30–90 across 20+ games.

At MEGARAMA GAMES, I buy AppLovin campaigns as an advertiser for 20+ iOS and Android games. I manage $20K–$40K monthly budgets and consistently reach 100% ROAS by day 30–90.

I built predictive ROAS models from cohort data to guide scaling, pacing, and payback decisions. I also turned creatives into playable ads for AppLovin and Unity Ads, handling briefs, production, testing, and refresh cycles.

At KISEKI, I led user acquisition for a subscription app and web platform on $200K+ monthly spend. Structured creative and funnel experiments cut CAC by 42% while scaling spend by 33%.

I built and launched SPARA, a subscription tracker app for iOS and Android, with in-app event tracking and localized app store listings across 9+ storefronts. I also built an AI creative pipeline with n8n, Claude, and Higgsfield to produce ad variations for testing.
