Finance and International Business professional with a specialization in Financial Management. Self-taught MQL5 and Python developer focused on algorithmic trading, multi-asset portfolio construction, and quantitative risk management.

My work centers on designing, optimizing, and validating Expert Advisors that operate as a coordinated portfolio rather than isolated strategies. I apply correlation analysis, temporal coverage mapping, and asset class diversification to build systems that do not rely on a single instrument or a single approach.

I currently manage algorithmic portfolios spanning forex, indices, metals, energy, and US equities, operating across multiple sessions and timeframes simultaneously.
I share my experience through technical articles and open-source tools in this community. I believe the shift from "building individual EAs" to "engineering portfolios" is the transition that separates retail from institutional thinking, and that principle guides everything I publish here.
