Sofia Ivanova
Head of Customer Success
Sofia leads customer success at Traders Casa. Most of her week is spent in conversation with traders — walking new users through their first backtest session, untangling journalling workflows that have stopped working, and collecting the questions that end up shaping the product roadmap.
That puts her closer than almost anyone to how backtesting software actually gets used: which steps trip people up, which metrics get misread, and which habits separate the traders who steadily improve from the ones who stall at the same point for months.
She writes the guides here so the answers she gives one trader at a time are available to everyone.
