Senior Growth Product Manager for B2C mobile and subscriptions

I work on onboarding, conversion, monetization, pricing, paywalls, and experimentation. I have 8+ years of product experience across consumer mobile, marketplaces, and streaming.

Based in Belgrade, Serbia. My primary setup is a full-time remote B2B contract from Serbia. I am open to hybrid roles when relocation is included.

Mobile monetization and experimentation

I owned 53 end-to-end A/B tests across monetization, onboarding, and product quality, with a 43% win rate.

Pricing, paywall, and offer experiments grew Android revenue about 40%. I used retention and refund rates as rollout guardrails.

CS.MONEY

Product Owner, Core Marketplace · 2020–2022

Core marketplace rebuild and staged migration

Funnel analysis showed that Trade and payment flows, not registration, were the main growth constraint. I moved from onboarding to own the core marketplace, then used around 100 customer interviews, surveys, usability tests, and product data to guide the rebuild.

Top-up conversion tripled, completed trades doubled, and direct-purchase conversion increased by 30%.

I led 20 developers, 5 QA specialists, and 1 product manager. Releases moved from every 4–6 weeks to every 1–2 weeks, and we migrated millions of users to the rebuilt marketplace in stages.
