At PT Citra Tubindo Tbk (Vallourec SEA), I supported the Sunfish HRIS implementation for employees across Indonesia and Singapore as Co-Project Manager. I traced an overtime configuration error behind payroll inconsistencies and coordinated the fix with timekeeping, payroll, and the vendor.
I redesigned manpower planning from email submissions into a Power Query tool with a three-level approval process. I also built a performance campaign dashboard from SuccessFactors exports and automated status notifications for direct supervisors.
In my contract evaluation work, I assess LLM responses against defined criteria and design multi-interaction tests for instruction drift and retrieval inconsistency. I document silent failures as data-integrity risks and explain my evaluation decisions with structured rationales.
At Riqcom Services, I led a team of four consultants and served as project lead for system implementations. Earlier, as a Programmer at PT Barelang Konsultindo Mandiri, I built and maintained desktop and web applications. My projects include PoliCom, an offline RAG tool for Indonesian labor law, and an Excel inventory workflow shaped by a ChatGPT vs Claude stress test.
