Engineering and product, in one set of hands.

Four years at AstraPay, Indonesia's payment platform, where I do both engineering and product on the same team. I write the RFCs and ship the code: migrated 150+ legacy reports to BigQuery, upgraded a Java scheduler to virtual threads (75% fewer threads, 83% faster generation), and led a 9-person stream presenting monthly to the CEO. German B2/C1, used to running two roles in the same week.
