Building something complex? I help companies architect, build, and scale systems that actually work — from first commit to 1M users. And I can prove exactly how I do it. Why Clients Hire Me After 74+ Upwork contracts and $200K+ delivered, I've learned that most projects fail for the same reasons: unclear scope, wrong architecture decisions early on, and vendors who say "yes" to everything. I do the opposite — I ask hard questions upfront so we don't discover problems in production. How I Work: AI-Augmented Development I don't just use AI tools — I've systemized them into a Multi-Agent Development Methodology: → Every decision documented and versioned (no tribal knowledge) → Full audit trail — see exactly how your project evolves → Real-time visibility into progress (not just status updates) → Clean handoffs — the next developer won't curse me What I Do → AWS Architecture & Infrastructure — Design, migration, optimization, security → Full-Stack Development — React, Angular, Node.js, Python, Java → Compliance Systems — HIPAA, SOC2, enterprise-grade security → IoT & Real-Time Data — AWS IoT Core, sensor networks, dashboards → Trading & Financial Systems — TradingView, Pine Script, algorithmic strategies Where I Add Most Value → Projects where "getting it right" matters more than "getting it cheap" → Systems that need to scale, comply, or integrate with complex infrastructure → Teams that want a technical partner, not just a code vendor → Rescuing projects that previous developers made a mess of → Teams who value documentation and full visibility The Numbers → 100% Job Success Score → Expert-Vetted status (top 1% of Upwork talent) → $200K+ earned on platform → 50+ developers in my agency for larger engagements → 22+ years building enterprise systems (Hewitt, Xerox, Cognizant) Certifications → AWS Solutions Architect – Professional → AWS Advanced Networking – Specialty → AWS Security, Cloud Economics, and Technical Professional Industries I've Built For Healthcare (HIPAA) · Fintech · SaaS · IoT · Insurance · Logistics · Manufacturing · Legal Tech How to Start Send me a message with: → What you're trying to build or fix → Your timeline → Any constraints I should know about I'll give you an honest assessment — including whether I'm the right fit.

I am a professional Algorithmic Trading Systems Developer specializing in designing, engineering, and implementing fully automated trading strategies across multiple platforms. My core expertise lies in transforming a client’s trading vision whether it is price action, Smart Money Concepts (SMC), DCA, martingale variants, breakout systems, scalping models, prop-firm survival engines, or custom execution logic into a robust, rule-based, mechanically executable trading system. Although my profile on this platform may appear newer, I am an established freelancer on other major freelance marketplaces with a strong portfolio and verified client reviews. You can review my portfolio to see my previous work history, complexity of projects handled, and authentic feedback from long-term clients. I do not sell strategies. I engineer them. My responsibility is to: • Accurately convert strategy logic into clean, optimized, non-repainting code • Ensure precise execution handling (spread, slippage, broker fills, liquidity realities) • Implement structured risk management (fixed risk %, equity protection, daily DD locks, basket control, etc.) • Design multi-position management systems (DCA, hedging, basket trailing, layered entries) • Build prop-firm compliant EAs with strict survival governance • Convert TradingView (Pine Script) strategies into native MT5 EAs • Integrate Telegram, webhooks, bridges, and cross-platform execution systems • Engineer anti-overfitting safeguards and realistic backtesting structures • Develop custom dashboards, panels, trade managers, and performance tracking systems I work extensively with: MT4 / MT5 (MQL4/MQL5) TradingView (Pine Script) cTrader (cAlgo) NinjaTrader Quantower SierraChart ATAS MultiCharts Thinkorswim AmiBroker Custom Python / Java automation systems for proprietary trading firms My development philosophy is strict: Execution precision > marketing performance Risk control > aggressive returns Mechanical rules > discretionary assumptions Robustness > curve-fitted backtests I clearly separate: Strategy logic responsibility (client-defined) Engineering responsibility (my scope) I guarantee correct implementation of rules. I do not guarantee profit metrics unless explicitly contracted for strategy research and optimization. I have delivered 1000+ automated systems including: • Price action EAs • EMA pullback engines • Donchian breakout systems • ATR-based scalpers • DCA / Martingale basket managers • Telegram signal copiers • Trade managers with equity control • Prop-firm survival EAs with daily/total DD enforcement • Multi-account anti-correlation execution engines What defines my role most clearly: I take complex trading ideas including multi-layer position logic, hedging mechanics, dynamic ATR systems, risk governance, session filters, execution protection, and broker-specific nuances and convert them into stable, testable, production-grade automated systems. I focus heavily on: • No duplicate orders -No repainting logic Real tick backtesting compatibility Accurate SL/TP placement after broker fill Spread and slippage awareness Clean modular architecture I build systems meant to run in real market conditions not just produce pretty backtests. And most importantly: I provide continued support after delivery. Bug fixes, refinements, clarification — I don’t disappear after handover.

Hello, I’m Ali Mukhtar. I build Python-based quantitative finance systems for firms, startups, and serious traders who need reliable infrastructure for research, backtesting, analytics, and execution. My work sits at the intersection of quant logic and production engineering. I’ve built trading platforms and finance products with FastAPI, pandas, NumPy, TA-Lib, backtrader, PostgreSQL, Redis, CCXT, Alpaca, Polygon, and AWS, including systems for backtesting, options analytics, market data pipelines, execution workflows, and performance reporting. I’m a strong fit if you need help with: ✅ Backtesting engines with realistic assumptions such as commissions, slippage, PnL, Sharpe, drawdown, and portfolio-level metrics ✅ Strategy research infrastructure using Python, pandas, NumPy, TA-Lib, and custom rule/indicator pipelines ✅ Execution and market data systems using APIs, WebSockets, async processing, and exchange/broker integrations ✅ Risk and performance analytics including trade attribution, fill analysis, reporting, and custom metrics ✅ Finance dashboards and APIs for trading, options, and market intelligence platforms ✅ Scalable backend systems built with FastAPI, PostgreSQL, Redis, multiprocessing, and cloud deployment A few examples of the systems I’ve worked on: Built backtesting platforms with realistic trade lifecycle handling, commission/slippage modeling, and 50+ performance/risk metrics Built strategy builder APIs that allow stacking indicators and testing systematic logic across historical data Built options and market analytics dashboards using Alpaca and Polygon data, including Greeks, IV, open interest, GEX, vanna, and charm views Built execution-analysis pipelines in Python to measure fill quality, VWAP, slippage, latency impact, and symbol-specific virtual fee models Built scalable trading infrastructure with isolated processes, async data ingestion, secure auth, and production deployment on AWS / Docker / Kubernetes I’m usually not the right fit for: Generic “quick script” work with no research depth Projects that ignore execution realism, slippage, or proper validation Lowest-cost shopping where engineering quality is secondary What you can expect from me: ✅ Finance-aware implementation, not just generic backend code ✅ Clean, maintainable Python code and well-structured APIs ✅ Realistic backtesting and analytics instead of inflated results ✅ Clear communication and thoughtful technical decisions ✅ A builder who understands both quant requirements and production constraints 🚀 Ready to build something serious? 📩 Send me a message and let's discuss how we can build something exceptional together!

I love programming, and there's nothing that can't be programmed. From trading bots, blockchain wallets, and Telegram bots to websites, automation tools, and entire platforms – anything is possible with code. Dear clients, I'm aware that many projects on Upwork are managed by agencies or intermediaries, often without technical expertise. That’s absolutely fine. However, I do not provide free ideas, consulting, or technical input for unclear or underfunded projects. If you value my time and expertise, I’ll be glad to support you – as long as the project is professionally structured and fairly compensated. Let’s work together efficiently and with mutual respect. "Cheap price, cheap code – Soon you're stuck in bug-load mode." ### Ich liebe es zu programmieren, und es gibt nichts, was man nicht programmieren kann. Von Trading-Bots, Blockchain-Wallets und Telegram-Bots über Websites, Automatisierungstools bis hin zu ganzen Plattformen – mit Code ist alles möglich. Liebe Auftraggeber, ich weiß, dass viele Projekte auf Upwork über Agenturen oder Vermittler abgewickelt werden – oft ohne technisches Fachwissen. Das ist grundsätzlich kein Problem. Was mir jedoch wichtig ist: Ich biete keine kostenlosen Ideen, Konzepte oder technische Beratung für unklare oder schlecht budgetierte Projekte an. Wenn Sie meine Zeit und mein Know-how in Anspruch nehmen möchten, freue ich mich, Sie zu unterstützen – vorausgesetzt, es handelt sich um ein professionell organisiertes und angemessen vergütetes Vorhaben. Lassen Sie uns effizient und zielgerichtet zusammenarbeiten. „Billiger Preis, billiger Code – Am Ende zahlst du die Not.“
