Product Owner & Lead Game Designer · Corochti Studio
I design games people stay in — and handle the design, monetization, data, and UA myself, so the feature, the numbers, and the revenue line up.

Deploy notes
Jul 2025 →Joined a startup with strong organic traction but no monetization infrastructure. I own the product end-to-end — economy, quests, FTUE, and retention loops — design every screen in Figma, and run an agentic-AI workflow for prototyping, features, and analysis.

- Built competitor benchmarking models (eCPM, IMPDAU, LTV from public signals) within 20% of actuals, used by UA for bids.
- Authored network-integration and UMP/GDPR compliance docs, protecting ~10–12% of EEA revenue at risk.
