I am a professional financial trader with over 20 years of experience across various roles, including trader, dealer, broker, and analyst. My background spans multiple asset classes with a focus on U.S. equities, options, and futures markets. I can help you with: ✅ Developing custom trading strategies based on your ideas or market concepts ✅ Backtesting and optimizing existing strategies using Python (Pandas, NumPy, TA-Lib, Backtrader, etc.) ✅ Building simulation environments to evaluate performance and risk ✅ Translating discretionary strategies into algorithmic logic ✅ Creating reports, visualizations, and performance metrics Whether you need a quick validation of your trading idea or a full pipeline from strategy to execution-ready code, I deliver results that are clear, robust, and grounded in real-market conditions.

My name is Shah. If you’re looking for an AI developer with real hands-on experience in trading system development (not just someone wrapping LLMs) you’ve found one. I’ve built my own AI trading bot from the ground up, so I understand both the technical and strategic challenges of developing and deploying intelligent trading systems. My focus is purely on Machine Learning (ML) and Reinforcement Learning (RL) models that make trading decisions, not on large language wrappers LLM like ChatGPT, DeepSeek or Perplexity. My experience spans from basic time-series forecasting models (like LSTM) to multi-agent architectures where each agent specializes in tasks such as forecasting, risk management, or portfolio rebalancing. Models and frameworks I’ve worked with: 1) Lagrangian-based models – For managing proprietary trading constraints, daily drawdown, and account compliance (e.g., FTMO-style rules). 2) QMIX Transformer + Graph Neural Network (GNN) – Multi-agent RL architecture for coordinated decision-making between agents. 3) Proximal Policy Optimization (PPO) – Policy-gradient algorithm for continuous control and adaptive market behavior. 4) Twin Delayed DDPG (TD3) – Actor-critic model for robust decision-making in continuous action environments. 5) Amazon Chronos-T5 (Hugging Face pretrained model) – A time-series forecasting transformer built on T5 architecture, fine-tuned for predicting future values such as price highs, lows, or returns. I’ve used it for multi-horizon forecasting and market condition inference. Each project integrates advanced learning methods such as Prioritized Experience Replay (PER), Hindsight Experience Replay (HER), Intrinsic Curiosity Module (ICM), meta-learning, and curriculum-based training, all aimed at accelerating learning and improving model stability. I perform all model training and validation locally on my RTX 4080 Super (16 GB VRAM), minimizing cloud GPU costs. Model tracking and visualization are handled with MLflow, ensuring all experiments are reproducible and data-driven. I also have hands-on experience with Quantower with C# API, MetaTrader 5 (MT5) and its Python API, used for automating data collection, backtesting, and integrating ML model signals into live trading workflows. While my direct platform experience is mainly with MT5, transitioning to other platforms (e.g., NinjaTrader, cTrader, or TradingView Pine) would not be difficult due to my modular development approach. If you’d like to learn more, feel free to reach out, I can show you examples of my current work. I don’t maintain a public GitHub repository, as most clients prefer their code to remain private, but I can share demonstrations via video call upon request.

I build production trading bots for futures, forex, and crypto — and I trade them with my own money on funded prop firm accounts. Most algo devs have never placed a real trade. I'm a certified funded trader with Topstep, MyFundedFutures, and Alpha Futures, with $2,400+ in live payouts on automated trading. I run a 5,500-line Python trading bot 24/7 on funded capital using ICT-based setups with strict prop firm risk controls (daily drawdown limits, max contracts, per-position risk caps). What I build: - Custom trading bots in Python (5,000+ LOC modular systems) - TradingView → Python webhook bridges (Pine Script → automated execution) - Broker integrations: Tradovate, MT4/MT5, Interactive Brokers, NinjaTrader, ccxt - Telegram control interfaces - Backtest engines with realistic slippage and commission - Risk management layers (daily DD, position sizing, correlation filters) - Macro data feeds (CPI, FOMC, NFP event blackouts) Why clients hire me over other devs: 1. I trade what I build — I catch bugs that destroy live accounts 2. I understand prop firm rules cold (Apex, FTMO, Topstep, MFFU, and more) 3. Clean, documented, modular code you can extend 4. Verifiable funded account proof on request Send me your strategy, broker, and risk parameters. I'll tell you within 24 hours if it's buildable, what it costs, and how long it takes.

More than 7 years developing software for VoIP and about 12 years of experience in programming for various platforms and systems. I've got wide experience in: - C/C++, C# - SierraChart, Ninjatrader - development under the ARM and MIPS CPUs - Windows and *nix programming
