I build production-grade algorithmic trading systems — from signal research through live execution. 15,600+ documented hours building systematic trading infrastructure across equities, options, and futures. Currently running a 20+ agent autonomous platform in production: real-time OCC options flow parsing, Bayesian self-improving signal engine, regime detection, multi-model LLM orchestration, and automated risk management. What I deliver: → Trading bots & execution engines — IBKR TWS/Gateway API, order management, circuit breakers, position sizing (Kelly criterion) → ML signal pipelines — LSTM/GRU, XGBoost, LightGBM, ensemble models, feature engineering, walk-forward optimization → Backtesting frameworks — realistic slippage, commission modeling, Monte Carlo simulation, strategy validation → Options intelligence — flow analysis, IV surface modeling, Greeks-based screening, sweep detection → Full-stack dashboards — React/TypeScript/Tailwind frontends, FastAPI backends, WebSocket real-time feeds, Telegram bot delivery Stack: Python, FastAPI, React, TypeScript, TensorFlow/Keras, scikit-learn, pandas, NumPy, SQL, Pine Script, NinjaTrader, Ollama/LLM orchestration, Docker. Background: MBA in AI & Business Analytics (4.0 GPA) · MSc Financial Engineering candidate · CMT Level 1 candidate · Published author (financial fiction). I combine quantitative finance theory with production systems engineering — not research notebooks, but deployed, monitored, self-improving systems. Async-first. Output-focused. Available for immediate start.

I'm a Full-Stack Developer with 7+ years of experience building web applications, automation tools, Telegram bots, and trading systems. I specialize in Python (FastAPI, aiogram), JavaScript/React, and PostgreSQL, with a strong focus on delivering clean, scalable, and production-ready solutions. Also experienced in WordPress plugin development, PHP, and WooCommerce customization. What I build: 🤖 Telegram bots — business automation, notifications, CRM integrations, payment systems 📈 Trading bots & fintech tools — cryptocurrency trading automation (Bybit API), market analysis dashboards, portfolio trackers 🛒 Marketplace automation — price monitoring, competitor analysis, and product management tools for Ozon and WildBerries 🧠 AI-powered applications — OpenAI integrations, product description generators, smart automation pipelines 🌐 Full-stack web apps — REST APIs, admin panels, SaaS platforms with React frontend and FastAPI/PostgreSQL backend I'm self-driven, communicate clearly, and deliver on time. Whether you need a quick bot or a complex multi-service platform — I'll get it done right.

Most of my work sits between quant research and messy reality. Clients usually come to me with a strategy that looks fine on paper, but breaks once you ask uncomfortable questions. What happens in a volatility spike? What happens outside the last five years of data? What happens when the data itself is wrong? That’s where I spend most of my time. On the modeling side, I use ARIMA and GARCH mainly for short-term volatility and regime awareness, not as black boxes. When the horizon gets longer or the problem becomes cross-sectional, I move to factor-based analysis instead of forcing a time-series model to do something it shouldn’t. In several projects, the real blocker wasn’t the strategy — it was the data. I’ve rebuilt missing or inconsistent equity index history so strategies could actually be tested through periods like 2008, instead of implicitly assuming a post-QE market forever. That alone has killed more “great-looking” strategies than any performance metric. A large part of my work is data analysis that doesn’t show up in glossy reports: fixing time alignment issues between prices, returns, and signals; dealing with survivorship bias that sneaks in through vendor datasets; deciding when missing data should be reconstructed, and when it should invalidate the test entirely. The goal isn’t academic cleanliness. The goal is to avoid false confidence. In Python, I usually work with pandas and statsmodels to turn half-formed ideas into backtests that can survive scrutiny, not just optimization. I’m deliberately conservative with assumptions, because most strategies fail due to data shortcuts, not math errors. I also translate this kind of research into production-grade TradingView tools, building Pine Script v5 indicators that reflect the same risk-aware logic in real-time execution environments. If you need someone to sanity-check a strategy, pressure-test it against bad history, or explain why something works only in hindsight, I can help.

I'm not just a developer — I'm a trader. I have 3 years of real trading experience in stocks, forex, and gold. I also have 3 years of experience working with prop firms (funded trading companies like FTMO, Funding pips, Funded Next etc.). This means I don't just write code — I understand what you're trying to achieve. Here's what I can do for you: ✅ Build Trading Bots (Expert Advisors) for MT4 & MT5 You have a trading idea or strategy? I'll turn it into a fully automated bot. It will include proper risk management — like stop loss, take profit, trailing stop loss — so your account stays protected. ✅ Build Custom Indicators for MT4 & MT5 Want a special indicator that shows signals on your chart? I'll build it exactly the way you need it. ✅ Backtest Your Strategy (MT4/MT5) I'll test your strategy on years of past market data so you can see how it would have performed — before risking real money. ✅ TradingView Indicators in Pine Script I can build any indicator on TradingView using Pine Script — the platform's coding language. Clean, accurate, and easy to use. ✅ Backtest on TradingView I'll run your strategy through TradingView's backtesting tools and share a full performance report with you. Your strategy is not hard — it's just in the wrong hands! When you work with me, you get someone who: Has actually traded live markets Can help to build your psychology Knows what prop firm rules look like Speaks fluent English Provide support after the project You are welcome to discuss your strategy with me.

I'm a backend developer focused on building reliable, scalable, and maintainable systems for web applications, APIs, trading tools, and data-driven platforms. My main expertise is in designing and developing backend services, REST/gRPC APIs, database architecture, automation tools, trading automation systems, and cloud-based platforms. I work with a strong focus on performance, clean code, stability, and long-term maintainability rather than just making something "work." I have hands-on experience developing trading-related tools, including MT4/MT5 Expert Advisors, indicators, copy trading systems, TradingView/Pine Script indicators and strategies, trade signal/alert tools, and automation logic for real trading environments. I understand the importance of low latency, accurate order handling, duplicate prevention, symbol mapping, error logging, notifications, and stable behavior under VPS/server operation. I have also built backend systems that handle real business logic, external API integrations, data processing, authentication, admin features, background jobs, monitoring, and production operations. I am comfortable working across the full backend lifecycle, from system design and implementation to testing, debugging, deployment, and ongoing improvement. My core stack includes Go, Python, TypeScript/Node.js, MQL4/MQL5, Pine Script, PostgreSQL, MySQL, Redis, Docker, Linux, and cloud environments. I can also support frontend or infrastructure tasks when needed, but my strongest value is delivering solid backend and trading automation foundations that are efficient, robust, and easy to extend. I care about clear communication, practical solutions, and building systems that help clients operate smoothly in real environments.
