Quantitative Developer | Algorithmic Infrastructure Engineer
em
Independent Quantitative Developer
I engineer institutional-grade trading systems designed for high-volatility environments. My core focus is bridging the gap between raw data logic and precision execution. I do not build "black-box" systems; I deliver transparent, rigourously tested, and modular infrastructure.
Technical Architecture
My development stack is optimized for low-latency execution and system stability:
MQL5 & MQL4: Native algorithm development, custom symbol engine architecture, and memory management for complex Expert Advisors.
Python: Quantitative data integration, REST API connectivity, and cloud-backend infrastructure for remote trade management.
Pine Script: Strategy migration; systematic conversion of TradingView logic into robust, automated EAs for MetaTrader.
C++: Optimized HFT logic and low-latency execution paths for rigorous trading environments.
Core Competencies
Advanced Bug Hunting: Systematically isolating execution loops, logic errors, and compilation failures.
SMC Automation: Identifying Order Blocks, Fair Value Gaps, and Liquidity sweeps with precision logic.
Custom Systems: Screen scanning, instant signal routing (Telegram/Discord), and dynamic trade management.
If your current system is missing trades, miscalculating lot sizes, or triggering errors, I will diagnose the architecture and rebuild it for stability.

Pro Spread Monitor Pro Spread Monitor is a specialized, professional-grade utility designed to provide real-time, low-latency monitoring of market spreads directly on your trading chart. In high-volatility environments, sudden spread spikes can significantly impact your execution quality and the integrity of your stop-loss levels. This indicator provides immediate visual feedback, allowing you to identify "danger zones" instantly and avoid trading during periods of unfavorable liquidity. Key
