🏛️ 𝐀𝐥𝐩𝐡𝐚 𝐝𝐢𝐞𝐬 𝐢𝐧 𝐛𝐚𝐝 𝐢𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞. Brilliant quantitative logic is worthless if your execution architecture bleeds capital under live-market pressure. I see it constantly: founders deploying systems that print money in backtests, only to watch them collapse in production because their MT5 terminals or TradingView webhooks aren't properly bridged to a high-performance backend. I solve this. As a Quantitative Systems Architect, I build sub-millisecond Python execution vessels that turn fragile, isolated trading scripts into resilient, production-ready infrastructure. With deep experience in financial market infrastructure, I specialize in Project Rescue and Scale-Up Architecture. I act as your hands-on Technical Partner: one single point of contact, strict engineering rigor, and absolute risk control. ━━━ 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 ━━━ Algorithmic Trading & Execution Engines Architecting institutional-grade automated systems natively across MT5 (MQL5) and TradingView (Pine Script v6). Building sub-millisecond Python execution vessels, utilizing WebSockets and ZeroMQ to route signals instantly from your Master API to the broker. Trade lifecycle management: precise order chunking, slippage caps, and dynamic trailing logic. Fintech SaaS & Prop Firm Infrastructure Designing high-concurrency B2B dashboards and server-side risk management microservices (Next.js, FastAPI, MetaApi). Enforcing strict Prop Firm drawdowns, daily loss locks, and automated equity syncing to protect capital from emotional trading. Bridging traditional frontend terminals (MT5/TV) with robust Python backends. Broker API & Data Pipelines Direct integration with Rithmic (R-API+), Binance, Bybit, and FIX protocols. Structuring historical MBO, tick-level, and order-book data ingestion pipelines (e.g., Databento) for accurate backtesting and ML-feature extraction. ━━━ 𝗪𝗛𝗬 𝗙𝗢𝗨𝗡𝗗𝗘𝗥𝗦 & 𝗤𝗨𝗔𝗡𝗧𝗦 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 𝗠𝗘 ━━━ I Understand Both Software Engineering and Quantitative Finance I speak your language. I don't just understand basic SL/TP; I understand Level 3 Order Books, Liquidity Voids, Lock-free Ring Buffers, and Structural Risk Validation. I don’t approximate your logic; I implement your mathematical models exactly as defined. Exact Logic, No Guesswork I build systems from the ground up with strict determinism. Every rule is coded, logged, and tested. If a condition is ambiguous, I clarify it before execution to ensure the system behaves 100% as expected under live-market stress. Zero Hand-Holding Required As your Fractional CTO, I don't just write code blindly. I audit your architecture, tell you exactly what is causing latency or system failures, and execute the fix. ━━━ 𝗧𝗘𝗖𝗛 𝗦𝗧𝗔𝗖𝗞 & 𝗣𝗟𝗔𝗧𝗙𝗢𝗥𝗠𝗦 ━━━ Languages: Python, C++, MQL5, Pine Script, TypeScript. Trading Platforms: MetaTrader 5 (MT5), TradingView. APIs & Data: Rithmic (R-API+), MetaApi, Databento, REST/WebSockets, FIX Protocol. Backend & SaaS: FastAPI, Next.js, ZeroMQ, Docker, Microservices Architecture. 🚀 Let's build something that scales. Send me your trading strategy, MT5 setup, or SaaS architecture plan. I will tell you exactly where the bottlenecks are and outline a strategic roadmap to fix them. ━━━ Keywords: Fractional CTO | Quantitative Finance Architect | Enterprise SaaS Architecture | Algorithmic Trading Systems | MT4 | MT5 | MQL5 | NinjaTrader 8 | NT8 | C# | TradingView | Pine Script | Prop Firm Tech Stack | Binance API | CCXT | Crypto Exchange Integration | Blockchain Developer | Web3 Infrastructure | DeFi Protocol | Payment Gateway Integration | Node.js | Next.js | Python | High-Concurrency Backend | Microservices | MetaApi | PCI-DSS | Project Rescue | High-Agency Developer
