About
Hi! I'm Sekar, a QA tester with a year in banking and mining and a developer's eye for where bugs like to hide.
Right now I'm testing the Organization and Benefit modules of Bank Mandiri's Integrated HC Suite Platform, the internal system that manages human capital across Indonesia.
Before QA, I built web apps with PHP and MySQL. That helps me trace bugs from the front end all the way to the database, so my bug reports point developers straight to the cause.
