At Cofounderie, I worked across client products as a Fullstack AI Engineer, contributing to mobile apps and leading backend and AI engineering for Solus's library search platform. I improved its RAG-based conversational search, including raising retrieval match density by 59%.
I built a multi-provider LLM abstraction and evaluation harness that screened model-platform pairs for production use. After migrating to the top-ranked model, the misbehavior rate fell by 64% against the prior baseline.
Previously, at PT. Infosys Solusi Terpadu, I built web applications with React, Vue, and Next.js, including Indonesia’s first ATM management information system and internet banking apps for BTN and CIMB. At Frisse Blikken, I helped develop a tutorial app for elders and disabled individuals that won second place at the Fresh Award 2020.
