What I'm looking for

I’m looking for a role where I can own end-to-end product features at the intersection of AI and React/React Native—building fintech/crypto experiences, improving delivery speed, and collaborating through mentorship and knowledge sharing.

I’m an AI Engineer and React/React Native developer with 6 years of experience building fintech, crypto, healthcare, and AI-driven products. I’ve worked across greenfield development, feature delivery, and team migrations between native React Native and React.js stacks.

In my current role at Estable IO, I maintain and build AI Engineer and React/React Native wallet features to buy, sell, convert, and send crypto. I’ve also contributed to an IPP greenfield MVP from scratch, where I help create new end-to-end capabilities.

Earlier, I accelerated feature delivery by 20% and improved team productivity through knowledge transfer and mentoring during React Native development and internal app work. I’ve also contributed to ground-up products using React Native, Redux/Redux toolkit, TypeScript, Next.js, and native integrations (CocoaPods and Gradle), with experience in AI workflows and automation.
