Developed a web interface that shows detailed information about a business that the user is searching for, and at the same time returns all the businesses inside a polygon drawn on a map using the chosen mode of transport and distance of travel. We used Angular, Flask, and Neo4j.

During the covid crisis, a lot of our clients were not able to open their stores. So we build them enterprise-level E-commerce websites using Angular and Flask. And We made the websites extremely fast by adding server-side rendering and built a fast Nginx configuration.
