Operations.
Research.
Better decisions.

I turn financial data into decisions and build the systems behind them. My background spans treasury operations, liquidity, and financial client relationships; since leaving Ajaib in 2024, I have built and operated an independent automated trading workflow covering scanning, signals, execution, and exits. Based in Jakarta, Indonesia and open to international and remote opportunities.
