Python developer · market analyst · Malaysia

I turn market data into tools people use. I work on palm oil and commodity derivatives, and I build the pipelines, dashboards and calculators behind that work in Python: from pulling prices and news out of LSEG/Refinitiv to self-updating public reports on palm oil, Bursa Malaysia and the S&P 500.
