Sachin Kahawala

Senior Data Scientist & AI Architect based in Melbourne, AU.

I'm a Data Scientist and AI Engineer with 6+ years of experience and a PhD in Artificial Intelligence. I design, build, and ship AI and machine learning systems across research and industry, spanning generative AI, deep learning, forecasting, and computer vision.

I'm comfortable end-to-end: rapid prototyping, experimentation, and production deployment on cloud platforms, with a track record of delivering reliable, measurable outcomes on complex, data-intensive problems. My algorithmic foundation comes from years of competitive programming.

Currently leading the design and delivery of production AI systems at PS Hummingbird, with a focus on LLM pipelines, multi-agent workflows, and the evaluation infrastructure that makes them safe to ship.
