What I'm looking for

I'm interested in AI language quality assurance and speech recognition projects.

At PT Pegadaian, I cleaned and validated operational datasets for internal reporting, prepared reports and dashboards, and used Python and SQL to investigate inconsistencies.

At PT Pegadaian (Persero) - Pegadaian Syariah Gatot Subroto, I process and verify customer records and review payment estimates, notifications, and supporting documents. For my undergraduate thesis, I developed and evaluated a Python-based logistic regression model using customer-related data for Pegadaian Kreasi Multiguna.
