At RieltBay, I run a 2M-MAU real-estate classifieds product across web, iOS, Android, and Huawei. I moved web advertising from flat-rate sales to programmatic CPM, growing revenue to $30–50K MRR while improving CTR.

I own product analytics, experimentation, backlog, and releases for squads of 5–13. My dashboards in ClickHouse, Grafana, and Firebase guide management decisions, while my A/B tests, ASO work, and pricing models have improved product outcomes and unlocked new directions.

Previously, I owned the acquisition-to-retention funnel for a 5M-MAU EU-licensed B2C platform, reducing CAC by 5% and increasing LTV by 9% and ARPU by 8% year over year. I rebuilt signup and payment flows, ran monetization mechanics, managed acquisition budgets, and coordinated partner integrations.

Alongside my full-time work, I founded Marb and launched three subscription products to paying customers, reaching 110 subscribers and $35K+ in revenue. I build, deploy, validate, sell, and measure products myself, drawing on a frontend background in TypeScript, React, and Next.js.
