Building an app portfolio to $60k/mo after Apple froze his developer account

TL;DR: Viktor Seraleev is an indie mobile app developer who has launched 30+ apps since 2020, primarily in photo/video and utility spaces. He had to restart his business three times - once going solo, once from lack of traction, and once when Apple terminated his developer account due to a naming conflict with former partners. His first solo app (a before-after slider for Instagram) grew from $200 to $34k monthly and sold for $410k. His key strategy is launching personal challenges (build 10 apps in a year) to force small bets and fast iterations, then learning which to scale, sell, or shut down. He uses subscription-only monetization (no ads) and diversifies across ASO, Google Ads, social media, and TikTok.
