I was working with Traveling API with multiple services: main backend is written on legacy C# .Net Framework 4.0 code for all business logic, which is the brain of this API, GraphQL server is written on js using Nest.js and Apollo service, Salesforce service, MuleSoft, Hygraph and appolo for front site. During this project, I was working on supporting legacy C# logic, rewrote old logic to a new GraphQL server, working with some integration stuff: lambda integration in AWS, and MuleSoft integrations, and also working with payment service and integration with CyberSource. Also, I was working with a door builder system, using PHP, Laravel, and PostgreSQL on the back, and next.js on the front. I work with a builder system, where customers create products and choose specific options for products, for example, picking colors for the door or handle color, and see how those changes apply to their door. During this project, I created endpoints for builder functionality in the PHP Laravel backend server and stored the completed product in the AWS s3 bucket, for this project I mostly worked with frontend functionality

I worked with React Native + Node.js applications, recording apps, and business web apps. For this work, I used a custom engine of the company, which is based on React Native and connected to the MongoDB database via racer
