ZHENG YUAN O.

Top-Rated Python Engineer specializing in financial technology and AI-driven enterprise operations. I don't just write scripts; I build production-grade architectures that handle high-stakes logic. From low-latency algorithmic trading bots (MT5/TopstepX) to autonomous AI workflows (n8n/Claude) and complex data pipelines. 🚀 What I Can Build For You: ✅ Algorithmic Trading & Financial Bots: Developing low-latency, automated trading execution systems. Expertise in custom logic (VWAP, Martingale, Close-Price strategies) integrated seamlessly with MT5, TopstepX, and Telegram signal parsing. ✅ AI Pipelines & Business Automation: Designing autonomous data engines utilizing LLMs (OpenAI, Claude) and n8n/Python. I connect disparate enterprise systems (Google Sheets, CRMs, webhooks) to eliminate manual input and scale operations. ✅ Custom Dashboards & Internal ERPs: Turning complex datasets into interactive, client-ready visual reports and management systems using Streamlit, FastAPI, and PostgreSQL/DuckDB. ✅ Enterprise Data Extraction: Engineering resilient, modular Python pipelines (Playwright, Selenium, Docker) to bypass complex anti-bot protections (Cloudflare, Incapsula) and deliver clean, structured data for business intelligence. 🔹 Real-World Project Highlights: - Automotive Inventory & ERP System: Architected a full-stack operational platform replacing legacy Excel workflows. Drawing on deep, hands-on experience managing real-world automotive dealership operations, this system handles real-time sales tracking, commission logic, and automated reporting with exact business precision. - High-Frequency Trading Automation: Delivered complex execution bots (including recent high-value MT5 and TopstepX integrations) handling split-second signals and multi-step logic, ensuring zero slippage and highly reliable state management. - Enterprise-Grade Discipline: Forged as a Software Engineer at Foxconn working on large-scale manufacturing systems, I bring rigorous testing, modular code, and structured documentation to every freelance contract. I am available for strategic infrastructure development and critical system architecture. Let's discuss how my engineering can scale your operations and save you hours of work today.
