AI Lead Engineer at ADS Digital Partner, Jakarta. I build LLM systems that have to run on someone else's hardware, inside their network — multi-tenant agent control planes, asynchronous document-to-answer pipelines with a GraphRAG layer, and NLP inference for Indonesian and its regional languages. Permissioned ledgers are the other half of the work.
Towards Trustless Academic Records in Higher Education
Peer-reviewed at IEEE 3ICT 2025. Blockchain and IPFS for verifiable student credentials. I engineered
the permissioned Hyperledger Besu network, the verifiable-credential contracts with role-based access
control, and the IPFS storage layer. 3rd of 9 authors.
34 open models on Hugging Face
Spam, hate speech and abusive language, sentiment, emotion, NER, topic modelling, language identification
and social bot detection — most of them for Indonesian, Javanese, Sundanese and neighbouring languages,
where good open models are thin on the ground. Curated into
NLP Indonesia Multitask
and Bot Detection.
