I've shipped AI-powered Flutter apps that drive retention, subscriptions, and growth for millions of users.
IndiaWhat I'm looking for
At Lingopanda, I build real-time AI voice, chat, and avatar learning experiences for a language-learning app with 2M+ installs and $700k+ ARR. I use OpenAI, Gemini, ElevenLabs, WebSockets, and WebRTC while owning onboarding, paywall experiments, retention features, and 99% crash-free releases.
I've also led Flutter delivery across client products at Novas Arc and built mobile growth, monetization, analytics, and real-time communication features at Pingolearn, Alemeno, and Duckcart Services. I enjoy taking mobile products from implementation through experimentation, performance optimization, and production rollout.
