Hi!👋 I'm Isaac.​

My focus is on making AI systems scalable and maintainable. Currently I'm a Staff Machine Learning Researcher at Wrike's Machine Learning team.

Previously at Clarifai, I led custom enterprise solution development for visual search and text moderation, built multi-modal retrieval systems, and led applied research in improving question-answering systems. I have spoken at various Python, ML conferences, and meet ups in Europe. My stack includes Python, Docker, Kubernetes, PostgreSQL, and Go.

My background is in Aerospace Engineering and Machine Learning and I hold undergraduate (B.A.Sc in EngSci) and graduate (M.A.Sc) degrees from the University of Toronto.

I work remotely in Europe, currently based in Tallinn, Estonia. In my spare time, I try to contribute to open source projects (e.g. MTEB), see the world, and stay active.
