Universal server application

Backend stack: Nest.js-Prisma.io-PostgreSQL. The stack on the frontend can be anything. In my tasks I used Next.js. Developed from scratch. Can be scaled and used for different purposes.

Responsibilities & achievements

I used this application to maintain the admin panel of an online store. Also, a separate copy of this application was used for the CRM system. Among the completed tasks: - development of user authorization strategies - preliminary data caching - development of a hybrid architecture with partial use of microservices. - processing and validation of incoming requests. - development of a system of request queues and elimination of duplicate requests (queue with Bull.js). - development of a task scheduler service. - development of a multi-tenant structure - setting up API authentication

Responsibilities & achievements

Creating new functionality based on the project specification, Development of a survey functionality, Adding new functionality to existing code, Working with change requests, Create custom functionality, Data migration, Deploy, Communicate with client , Manage code on front/back end Technical challenges: It all started as a small project for the client and his friends. And it was decided to do it on Firebase, as it would be faster and cheaper. But after 2 months, we decided to add a number of functions that were not included in the tasks before (chat, settings, notifications via mail and mobile phone, etc.). So, after analyzing all the requirements that had to be implemented, a decision was made to migratе on NestJS , as these are more rational technologies for this flow of tasks. Was engaged in a complete migration to new technologies and it gave a benefit in work productivity
