Front-end Developer, Platform for Launch App Store

July 2020 - February 2022
Description: It is a platform that allows customers to build, brand, and launch their own app store platform, which is easily submitted by developers, discovered by users, and managed by the owner.The platform represents a full CRM system that allows set up sites. From app onboarding to payments, every function of the app store is powered by an API, keeping it flexible to meet
current and future needs. According to requirements, I was developing a library with customizable components, directives, and pipelines that can be implemented into other ReactJS apps and data processing services for Openchannel API. Also, I created a mono repository that included these libraries and developed ready-to-use customizable templates for Developer and Marketplace Portals. In addition, I implemented charts components, file uploads, and dynamic form generation based on a large configuration file.
