Francisco Javier Mesa Diez

Trading Systems Developer — MT5, TradingView, Python | EAs, Indicators, Dashboards, Bots & Integrations

I develop custom tools for traders: Expert Advisors, indicators, dashboards, risk-management tools, alert bots, and integrations between platforms.
If it runs in the trading ecosystem, I can build it — MetaTrader 5/4, TradingView (Pine Script), Python, Telegram, web dashboards, or connecting any of them together. From a one-hour fix to a complete trading system built from your specification.
Background: I've spent years designing, coding and running my own automated portfolios — including risk-control systems and prop-firm rule compliance. I validate my work with quantitative methods (Walk forward, MonteCarlo, etc...), so what you receive is not just code that compiles: it's code that has been tested the way a trader needs it tested.

Typical jobs:
• New EAs or strategy automation from your rules — any complexity
• Fixes and modifications to existing EAs or indicators
• Custom indicators and dashboards (MT5 or TradingView)
• Custom snippets, scripts, plugins or applications for your trading platform
• Risk-management and trade-management tools
• Telegram alerts/bots, MT5 ↔ Python integration, data pipelines
• Backtesting and quantitative validation of your strategy

What I don't do: sell signals or promise profits. You bring the idea — I deliver clean, documented, tested code, on time.
Communication preferably in English or Spanish but I could adapt to any language. Daily progress updates on every job.
