What I'm looking for

I'm open to contract work through Celebrus Inc. or a full-time role, remote in Canada or the USA, or hybrid in the Greater Toronto Area.

At Celebrus Inc., I built and deployed the Celebrus Health Platform on Azure, including an assistant that answers questions about patient documents and cites its sources. I also created CelebrusAI, an AI assistant with six plugins that can run on Azure OpenAI or a self-hosted Ollama model.

I built and published DocuFlexPro, a receipt scanner rated 5.0 on the App Store and Google Play, with offline on-device machine learning. Before Celebrus, I designed a background job framework at AVEVA that other teams adopted, and led the modernization of Manulife’s claims processing systems.
