Maven Clinic is a telemedicine company focusing on women's health. - Developed the early stages of machine learning models for the prediction of C-sections and NICU admissions at the patient level

- Founded the data science team and scaled it to six people from scratch: three data scientists, two analysts, and one data engineer. Sourced and recruited very actively and often handled the recruiting pipeline end to end - Wrote the original data pipeline: Airflow running Python and SQL jobs, all Dockerized and deployed to AWS - On the ML side, supervised my data scientists across various projects in computer vision (object detection for quality control, image recognition for mobile apps), assembly-line simulation, subscription churn, customer clustering, and health tracking https://medium.com/careof-tech/health-programs-our-vision-for-software-and-data-at-care-of-e66c6c187494
