As a co-founder, I was working on building & deploying Android & iOS mobile applications using React Native, responsive single-page application using React and backend on Node with GraphQL for API. All written from scratch on TypeScript with heavy use of code sharing.
I worked on the frontend using React & Vue, the backend using Python & Ruby on Rails, and API using REST, GraphQL, & RabbitMQ.
I have been freelancing as web developer since 2011. I have been building websites using modern technology such as React, Vue, TypeScript, & GraphQL since 2016.
