Daniel Sinaga

I lead internal platforms at PT Kaltim Parna Industri used by 325 staff across eight departments, including IRMS, LIMS, incident reporting, ISO compliance, and corporate web operations. I've decomposed shared monoliths into independently deployable services and digitised laboratory workflows, audit records, and risk assessments.

As an independent software consultant, I've delivered payment marketplaces with Midtrans and Xendit settlement automation, hospital e-procurement that reduced cycle time from 5–6 months to two months, retail POS and QR loyalty systems, and a sanitation platform recognised with 2nd Place in the Bontang Innovation Award.

Earlier, I built Spring Boot modules and transaction APIs for Bank Danamon's corporate cash management platform. I also ship production RAG and agentic workflows using LangChain and LangGraph, and I'm open to fully remote roles.
