Building NewZen Terminal · Galați, Romania · Open to Remote

I'm a Product Owner and Systems Architect based in Romania, currently building NewZen Terminal a proprietary multi-asset trading platform designed for traders who think seriously about the market.

I led the product from zero: defining the vision, designing the architecture, integrating live financial APIs, and coordinating dual AI orchestration using GPT-4o and Claude. The platform combines machine learning, macro data analysis, and trade journaling into one focused environment.

I have a strong background in forex trading with a macro first approach I study monetary policy cycles, central bank behavior, and build directional bias before I ever look at a setup. This market experience directly shapes how I think about product decisions.
