Cross-Platform Trading App in Flutter
Budget: ₹5,000 – ₹7,000 INR
I need a complete mobile trading solution built with Flutter for both Android and iOS, backed by either a Node.js or Laravel API and a MySQL database. For launch we must absolutely nail three customer-facing features—mobile-OTP registration and login, a real-time market watch screen, and reliable buy/sell order execution—so please make sure your architecture is able to stream data with low latency and queue orders safely even on spotty networks.
Authentication will be mobile OTP only for now; please factor in a scalable SMS gateway and any fallback logic you normally use. KYC upload, wallet management, deposit / withdrawal requests, trade history, P&L reporting, push notifications, a referral module, and integrated customer support (WhatsApp link plus click-to-call) come immediately after those core items.
On the back end I need a secure web admin panel where I can:
• create, suspend, or verify users
• approve deposits / withdrawals and review every transaction
• drill into analytics and reports (daily volumes, user activity, revenue, etc.)
A clean, intuitive UI is critical—I expect the same level of polish users see in top-tier brokerage apps. Please include animations, dark/light themes, and responsive layouts that feel native on both platforms.
Deliverables
1. Flutter source code for Android & iOS
2. Web admin panel source code
3. Database schema and seed data
4. API documentation (Postman or Swagger)
5. One-month post-launch bug-fix support
6. Signed NDA before code hand-off
When you reply, attach:
• a link to your portfolio and any live trading or fintech apps you’ve shipped
• a concise breakdown of your proposed tech stack (libraries, real-time data solution, hosting)
• estimated cost split across milestones and an honest timeline from kickoff to App Store / Play Store submission
• details of the support window you include by default and any paid extension options
Only apply if you have verifiable experience building secure, high-traffic fintech or trading platforms; generic app portfolios will be ignored.
