About Me
I'm a Junior AI Engineer at PT Sigma Cipta Utama, currently building production LLM systems and real-time AI infrastructure. Informatics graduate from Telkom University with a 3.96/4.00 GPA.
Day to day that means LLM agent pipelines, real-time audio/video over WebRTC, RAG systems, and the microservices holding them together. What I actually care about is whether the thing survives production: low latency, and not falling over at 2am.
I'm also applying for a MEXT research scholarship to continue AI research in Japan, on affective computing and multi-modal systems.
