Clipboard Health
https://clipboardhealth.com/For this project, I built the front end for landing and signup pages for a smooth onboarding experience using React, Redux, Ionic, and Sass. I also implemented RBAC for documents microservice using NestJS, GraphQL, and Apollo Client architecture and the caching layer for a microservice to improve the overall performance using Redis.
I also worked extensively with external APIs like Cloudinary, Salesforce, and Adjust to increase the number of onboarding users, migrated data from MongoDB to PostgreSQL using Mongo Listeners, and resolved multiple critical and urgent bugs to unblock users.
In addition, I automated the background verification process of signed-up customers using a third-party tool called Checkr, implemented a Webhook, and created the background verification process's UI/UX experience using React and Express.
Lastly, I created documents image proxy to improve the overall security of the documents uploaded by our users, collaborating across teams to deliver tasks and features quickly.
