You will build a groundbreaking AI-powered platform focused on empowering crypto traders through data-driven insights and real-time coaching. At its core, we're building an AI engine that aggregates anonymized trading data from thousands of users, categorizing it into "winning" (profitable) and "losing" (unprofitable) pools. This enables the AI to compare an individual's behaviors—such as risk levels, hold times, or asset diversification—against these benchmarks, delivering smart, personalized insights and nudges during live trading. For example, the system might alert: "Your 12x leverage on weekends matches losing traders (only 2.8% profitable)—winners average 24-minute holds; consider scalping." By pooling community data, we help users realign their strategies toward proven winning patterns, starting with crypto to iterate quickly.The platform will be broker-agnostic, requiring secure, read-only API integrations with 10-20 major crypto exchanges (e.g., Binance, Coinbase, Kraken, Gemini, Bitfinex, etc.) for data gathering without executing trades. We'll also include a community stats page for aggregated insights (e.g., comparing winners' vs. losers' average hold times or number of instruments traded) and a premium membership system offering exclusive access to anonymized open positions from winning traders, deeper simulations, and advanced nudges.This MVP will include a responsive website and cross-platform mobile apps (iOS/Android), with scalability for future asset classes. We're seeking experienced fintech developers or a small team to bring this vision to life, drawing from successful Upwork projects in AI trading tools and crypto apps.Scope of WorkAI Engine Development: Build the core AI system using ML/deep learning (e.g., clustering for winner/loser pools, predictive models for risk assessments).

Frontend Development: Design intuitive UI/UX for website (responsive) and mobile apps, including dashboards for personal insights, live nudges, and user profiles.
Backend Development: Create a secure server for user auth, data processing, and AI pipelines. Handle anonymized data storage and real-time monitoring.
API Integrations: Implement read-only connections to 10-20 major crypto exchanges (list to be provided; start with top 5 like Binance). Ensure seamless data pulls for trades, positions, leverage, etc.
Community Stats Page: Develop an interactive information hub displaying aggregated stats (e.g., "Winners hold trades 15% longer than losers" or "Losers trade 40+ instruments vs. winners' 2-3 focus"), with visualizations like charts and filters.
Premium Membership Setup: Integrate subscription tiers (e.g., via Stripe) where premium users access exclusive features like anonymized views of winning traders' current open positions, custom AI simulations, and priority nudges.
Other Features: User onboarding with API setup, push notifications (e.g., Firebase), analytics visualizations, and admin tools.
Security & Compliance: Encrypt data, ensure GDPR/CCPA compliance, and add user controls for data sharing.
