Hello, I'm Donny!
I am an AI/ML Engineer and Data Scientist with 10+ years of engineering experience, 7+ of them focused on production AI across speech recognition, LLMs, agentic AI, and computer vision.
I have delivered end-to-end agentic AI frameworks and voice AI solutions at Accenture, LLM-powered healthcare products at BitHealth, and Bahasa Indonesia ASR/TTS pipelines at Prosa.ai. I currently lead data migration engineering on an SAP S/4HANA transformation programme for a national telecom operator.
My work combines research depth (M.Sc. ITB, Sejong University) with hands-on production delivery.
I'm interested in AI/ML engineering roles, research collaborations, and freelance opportunities. However, if you have other request or question, don't hesitate to contact me.
