🚀 What I do

I'm a Product Engineer at Beyond Apps, currently building:

  • 🎬 MyZesty — AI video editor, 500K+ installs
  • 🧞 Genie — in development

Over 6 years I've shipped 50+ production apps across e-commerce, social, fintech, food delivery, fitness, and utilities. My home stack is native Android; I've also delivered client work in React Native, Flutter, C++, and web — I own outcomes, not a single stack.

💰 My specialty: apps that earn

Most developers can build features. I build revenue:

  • 📈 Ad mediation architecture — AdMob, AppLovin, IronSource waterfall & bidding setups that have lifted client revenue 25–30%
  • 🧩 Custom ad SDKs — remote-config-driven placement systems, A/B-ready
  • 🔐 UMP/GDPR consent flows — compliant and revenue-preserving
  • 💳 IAP & subscriptions — hybrid revenue models for service and content apps
  • 🏪 Store operations — launches, ASO, policy compliance across 50+ releases

✍️ Writing

I write about Android engineering and app monetization — fewer "hello world" tutorials, more "what actually moves revenue."

📈 By the numbers

50M+   combined downloads across shipped apps
50+    production apps in 6 years
500K+  installs on MyZesty (current product)
100+   five-star freelance orders · repeat clients in 8+ countries
25–30% typical revenue lift from my mediation & placement work

💬 Open to: monetization consulting (limited slots) · product-engineering conversations

"Revenue engineering is measured in dollars, not demos — it's the part AI code generators can't fake."
