About
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. Informatics graduate from Telkom University with a 3.96/4.00 GPA.
Currently at PT Sigma Cipta Utama, where I design and ship AI infrastructure that has to survive real traffic: RAG pipelines with users on the other end, real-time LLM services, and the plumbing around both. Latency and reliability are the parts I get stuck on.
Longer term, I'm applying for a MEXT research scholarship to Japan for postgrad research in affective computing and multi-modal AI.

What's Next
Pursuing a MEXT scholarship for postgrad research in Japan. What I want to work on is affective computing: how a system can read emotional and contextual signals and adjust how it behaves while the conversation is still going, not after the fact.
After that, I want to keep contributing to open-source AI tooling and publish more on LLM agent systems, ideally from a remote team that ships to real users.
still figuring most of it outWant to work on something?
I'm open to AI/LLM roles, research collaborations, and side projects.
