Experience
- Annalise Enterprise CXRhttps://annalise.ai/solutions/annalise-cxr/
Annalise Enterprise CXR is a multi-view comprehensive chest X-ray decision-support tool.
I helped develop our initial machine learning (ML) models and led our latest release's continued iteration and deployment. I iterated upon our ML strategy, ran and documented extensive experimentation using state-of-the-art and novel techniques, liaised with product and clinical leads, and deployed and tested our healthcare AI in production. - Sypht Document Extractionhttps://go.sypht.com/ai-driven-ocr
An NLP-powered document information extraction solution with ≤5 seconds extraction time provided via REST API. I single-handedly developed the initial machine learning solution and then continued to contribute to it as the team grew.
