Junior AI Engineer — PT Sigma Cipta Utama

I'm M. Daffa Raygama, an AI Engineer building production LLM systems, real-time voice pipelines, and multi-agent architectures. CS graduate from Telkom University with a 3.96/4.00 GPA.

Currently at PT Sigma Cipta Utama, I design and ship AI infrastructure that runs in production from RAG pipelines serving users to a real-time LLM systems. I care about latency, reliability, and making AI systems actually useful.

Long term, I'm pursuing a MEXT research scholarship to Japan for postgrad research in affective computing and multi-modal AI.

What's Next

// goals & research interests

Pursuing a MEXT scholarship for postgrad research in Japan. My research interests sit at the intersection of affective computing, multi-modal AI, and human-AI interaction — specifically how AI systems can adapt their behavior based on emotional and contextual signals in real-time.

Long-term: contribute to open-source AI tooling, publish research on LLM agent systems, and work on global remote teams building AI infrastructure that matters at scale.
