Work experience
MQL4/MQL5 Expert Advisor Developer
FT 1844 Freiburg Sacristans • Freelance
Jul 2026 - Present • 3 mos
Developed automated trading systems for MetaTrader 4 and MetaTrader 5 using MQL4 and MQL5. Implemented strategy rules, configurable entry and exit conditions, stop-loss and take-profit settings, trailing stops, and position-management logic. Worked on converting trading strategies into executable Expert Advisors while ensuring that parameters could be adjusted without modifying the source code. Conducted strategy tests using historical market data, reviewed trade logs, investigated execution errors, and refined the EA logic when results differed from the intended strategy. Also worked on input validation, order handling, and compatibility testing to improve reliability across supported terminal environments.
Forex EA Testing and Optimization Specialist
CV. Éxito Bali Group • Part-time
Apr 2026 - Present • 6 mos
Tested and refined automated trading systems using MetaTrader Strategy Tester and available historical market data. Reviewed backtesting reports to assess profitability metrics, maximum drawdown, trade distribution, recovery factor, and sensitivity to strategy parameters. Compared configurations to identify weaknesses and potential overfitting rather than selecting settings solely because they produced the highest historical return. Investigated issues involving order execution, stop-loss placement, trading-session filters, spread conditions, and inconsistent strategy behavior. Documented test assumptions and limitations, checked results under different market conditions, and prepared clear technical findings to support development decisions before any forward or live-market evaluation.
Python Quantitative Trading Tools Developer
Grey Pine Grp • Freelance
Oct 2026 - Oct 2026 • 0 mos
Developed Python-based tools to support trading-system analysis, historical data processing, strategy evaluation, and automated testing workflows. Worked with structured market data to calculate trading statistics, compare strategy configurations, inspect entry and exit behavior, and organize test results for further analysis. Used scripting and data-processing techniques to reduce repetitive manual work and make strategy evaluation more systematic. Investigated discrepancies between expected and observed results, checked data quality, and organized outputs into reports that made performance metrics easier to interpret. Where applicable, used Python alongside MT4 or MT5 workflows to support research and validation of automated strategies.
