Stock Trading App Development

I need a seasoned mobile developer to create an Android-first trading application that lets users buy and sell stocks in real time. iOS support can follow, so please indicate in your proposal if your stack allows an easy cross-platform rollout.

Core user flow
Users should be able to register with their mobile number, verify by OTP, complete basic KYC by uploading documents, then fund an in-app wallet and place live stock orders. I will provide or license the market-data API; you will integrate the feed and maintain low-latency order execution. A clean, fast and secure interface is essential, so pay attention to responsive charts, clear portfolio views, and smooth navigation.

Back-office requirements
An accompanying web-based admin panel must give me full visibility and control: approve or reject KYC submissions, monitor trades, adjust wallet balances, push notifications, and change credentials at will. Role-based access and solid audit logs are a must.

Tech expectations and deliverables
I am open to native Kotlin/Java, Flutter, or React-Native for the app and a modern framework such as Node.js, Laravel, or Django for the admin, as long as the final result is performant, well-documented, and secure.

Deliverables:
• Android APK plus source code
• Admin panel source and deploy docs
• API documentation (REST/WebSocket)
• Basic test report and build instructions

Please include your proposed tech stack, any previous stock-trading or fintech work, and the timeline you foresee for an MVP followed by production readiness.
