Mobile App Developer for Bitcoin Investing App

---

---

We’re launching a mobile app for 18-35-year-olds in the U.S. to invest spare change in Bitcoin (e.g., round a $3.50 coffee to $4, invest $0.50). Our goal is to rival Robinhood’s slick design, Acorns’ easy automation, and Coinbase’s trusted platform. We need a mobile app developer to build a simple, secure, and fun iOS/Android app for $2,500, launching in 5-6 weeks. You’ll use GitHub Copilot to speed up coding, but your expertise ensures fintech-grade quality and strict FinCEN/FINRA compliance. Task and Deliverables Build a cross-platform iOS/Android app using Flutter or React Native with these features: • Roundups: Link cards (via Wyre) and bank accounts to round purchases and invest in Bitcoin (e.g., $0.50 from $3.50). • Recurring Buys: Set weekly/monthly Bitcoin buys ($5+). • Wallet: Secure Bitcoin storage (via BitGo) with instant withdrawals to external wallets (e.g., Coinbase) in 1-2 hours. • Stack Streak: Gamified streaks for daily roundups with points, badges (e.g., “Week 1 HODLer”), and a leaderboard, shareable on X/Instagram. • Onboarding: 2-minute signup with a U.S.-friendly approach (via SumSub KYC, SSN for U.S. users), avoiding slippage • Educational Videos: Display 15-second clips (we provide). • Referrals & Bonus: $5 BTC for referred users investing $10; $1 BTC signup bonus. • Deliver a bug-free app deployed to app stores, with code on GitHub and clear documentation. Ensure all features comply with FinCEN MSB (money services business) and FINRA regulations, using secure data handling (PCI compliance via Wyre, 2FA, SEON fraud detection). Use GitHub Copilot to accelerate coding (we’ll provide access). Skills Required 1. Flutter/React Native: Build fast, smooth iOS/Android apps with responsive UI, like Robinhood. 2. Fintech API Integration: Integrate Wyre (payments, PCI compliance), Kraken (Bitcoin buys), BitGo (wallets), SumSub (KYC), SEON (fraud detection). 3. Crypto Wallet Management: Handle Bitcoin wallets with BitGo’s multi-sig APIs for secure storage/withdrawals. 4. Bitcoin Transactions: Enable fast, secure Bitcoin buys and transfers, like Coinbase. 5. 2FA Security: Implement SMS/authenticator 2FA for user trust. • Bonus Skills: Firebase for user data, AWS for scalability, Firebase ML for AI-driven roundup suggestions, FinCEN/FINRA compliance experience to support our legal team. Communication Expectations • Fluent English: Clear, prompt Slack updates and responses to questions. • Weekly Check-Ins: 30-minute Zoom calls every Monday at 10 AM EST to review progress and blockers. • Availability: Overlap with U.S. EST hours (9 AM-5 PM) for real-time collaboration, even if worldwide. • Transparency: Share progress via Slack (e.g., “Wyre API done”) and flag issues early. How We Work • Team Setup: You’ll work with me (founder) and a UI/UX designer (hired separately) on Slack. • Collaboration: Integrate designer’s Figma wireframes by week 5, test onboarding/withdrawals together to ensure no bugs. Use GitHub for code, TestFlight for testing. Work with our legal team to ensure FinCEN MSB and FINRA compliance (e.g., secure KYC, transaction logging). • Workflow: • Week 1: Start backend (Wyre, Kraken, BitGo). • Week 3: Integrate SumSub KYC, test APIs. • Week 5: Add Figma UI, implement Stack Streak. • Week 6: Fix bugs, submit to app stores. • Expectations: Meet deadlines, test thoroughly for Coinbase-like simplicity and security, use Copilot to save time. Prioritize FinCEN/FINRA compliance (e.g., PCI via Wyre, SumSub KYC, SEON fraud detection). We’re lean, so efficiency is key. • Payment: Upwork milestones (e.g., $500 for Wyre/BitGo setup, $500 for UI integration, $1,500 for final app). What We’re Looking For • Experience: 3+ years building fintech or crypto apps (e.g., payment/wallet apps), with a portfolio showing 2-3 relevant projects. • Rating: 4.8+ stars on Upwork, 10+ completed projects. • Worldwide Talent: Fluent English, EST availability. Miami-based or Bitcoin HODL knowledge (e.g., X/Reddit crypto communities) a big plus. • Passion: Excited to build a viral app in Bitcoin’s 2025 surge, rivaling Robinhood/Acorns/Coinbase and crushing Bamboo. How to Apply • Submit a portfolio with 2-3 fintech/crypto apps. • Answer: “How would you make signup as fast as Coinbase, ensure instant withdrawals like BitGo, and support FinCEN/FINRA compliance?” (1-2 sentences). • Confirm you can work for $2,500 and finish in 5-6 weeks. (Please nail the interface, simple and fun) Why Join Us • Build a hot crypto app for U.S. HODLers, • Potential for future work as Drip grows (20,000 users in 3 months). • Be part of a lean team creating a fintech hit, with a shot at a hit app
