⭐⭐⭐⭐⭐ NinjaTrader, MT4/5, TradingView, IBKR, QuantConnect, AI Trading ⭐⭐⭐⭐⭐ I help traders get high-quality results on time without the risk of hiring the wrong developer. I build algorithmic trading bots and strategies for forex, futures, stock, crypto traders using Ninjascript, MQL, Pine Script, Python, Freqtrade, Backtrader, and CCXT. I help independent traders and small funds automate entries/exits, visualize edges, and get instant notifications to catch opportunities faster. I design systems to stay consistent across market regimes, withstand noise, slippage, latency, and partial fills, avoid overfitting, degrade gracefully when assumptions fail, and handle real-world edge cases like weekend gaps, news spikes, and low liquidity. ✅ Trading Platforms • IBKR TWS & IB Gateway API integration (ib_insync) • NT7 / NT8 strategies, indicators, addons • MT4 / MT5 indicators, Expert Advisors, • TradingView Pine Script indicators, strategies, screeners, alert webhook bridge • MultiCharts, QuantTower, Sierra Chart, Thinkorswim, Charles Schwab ✅ Backtesting & Quant Research • QuantConnect, VectorBT, Backtrader strategy backtesting, risk analysis • AI / RL strategy development (SB3, Gymnasium, SAC / PPO / A2C) ✅ Risk Analysis & Risk Management • Pre-trade risk checks (position limits, leverage) • Real-time P&L, drawdown & exposure monitoring with kill switches • Liquidity & execution risk (slippage, widening spread, commission, exchange fee) • Strategy risk validation (overfitting detection, walk-forward testing) ✅ Market Data & APIs • Stock market API integration & subscription cost optimization (IQFeed, DxFeed, Massive, AlphaVantage) ✅ Infrastructure, Observability, Data • Execution Engine • Kafka, Redis • Grafana, Prometheus • Trading performance monitoring dashboards • Time-series databases & tools: QuestDB, InfluxDB, TimescaleDB, ClickHouse, kdb+, ✅ Products & Licensing • Charting applications in C# Avalonia, Next.js • Copy trading tools • Trading product licensing ==================================================================================== "I believe the current trade I am in will be a loser ... a big loser at that." Larry Williams "Throughout all my years of investing I've found that the big money was never made in the buying or the selling. The big money was made in the waiting." Jesse Livermore "Don’t focus on making money, focus on protecting what you have." Paul Tudor Jones "In trading, you have to be defensive and aggressive at the same time. If you are not aggressive, you are not going to make money, and if you are not defensive, you are not going to keep the money." Ray Dalio "Amateurs think about how much money they can make. Professionals think about how much money they could lose." Jack Schwager

I have always enjoyed working with him and my mind is always at peace when he is handling a project for me. I recommend him always and assure you wont regret it.

The code quality was clean, modular, and easy to maintain, showing strong understanding of best practices. Communication was clear throughout the project, with regular updates and quick responses to feedback. Overall, a skilled and reliable developer—I would definitely invite him for upcoming projects.

Financial prices and times database performing fast and with many tools present in the different technical analysis softwares like Multicharts, Tradingview, Metatrader5.

The worst experience I've ever had with a developer. After four months of work, he asked me to pay him for half the work, even though he hadn't reached any milestones and even though the agreed-upon terms stipulated he'd be paid when the project was finished. The reason he gave for wanting to be paid and abandoning the project was that he would have earned more with another job. Don't believe this person, otherwise you'll be left with an incomplete project and you'll have wasted your time.
