About Me

Hi, I'm Vishnu. I've been programming since I was a kid. Over the years, I've worked on many applications for various platforms.

I grew up in New Jersey, went to Cornell University for undergrad, graduated with an MD from Albany Medical College, and recently completed a residency program in Internal Medicine. My focus has been on developing apps that help healthcare providers take better care of their patients.

Below are some examples of my personal projects.

Selected Projects

Machine Learning


iOS & Android App


Mobile app that uses machine learning to prioritize radiology reports based on urgency of the findings. The physician can view the reports and act on them directly from the app.

Winner of MIT Hacking Medicine prize at Brigham and Women's Hospital Hackathon.

Cyberbully defense training chatbot


Built for HackRU 2016 at Rutgers University

Chatbot designed to help kids deal with cyberbullies by training with a virtual bully in a safe space. Users can interact with Regina over Facebook Messenger or SMS. Regina works with a Dialogflow model trained with examples of bully-victim conversations and uses the IBM Watson Tone Analyzer to determine the confidence level of the user when standing up to the virtual bully.

Off the Record

Private communication between teens and pediatricians


Built for InnovateNYP Pediatrics Challenge 2016 at New-York Presbyterian Hospital

As a teen, it’s embarrassing and awkward to openly ask your doctor questions about things like drugs, alcohol, and sex when your parents are in the room. Teens can text a number specific to their doctor which connects them to a secure messaging portal and delivers their message privately to their pediatrician's electronic health record prior to their visit.
