1. Problem 1: Lack of control on the Seller details getting occasionally exposed from the Admin Board (Authentication layers)
2. Solution: To resolve this, a dedicated service for admin users (BFF) was created, implementing request authentication through middleware. Advanced checks were introduced, including automatic token expiration after an hour of inactivity or if a user logged in from two different devices. Furthermore, all admin board login activities are logged in the database, resulting in a successful implementation of a secure system.
3. Tools Used: Django, MySQL, Redis Cache Coding Design Patterns: BFF Design Pattern
4. Problem 2: Document generation is challenging due to a variety of large file types, such as PDFs, CSVs, and Excel files, typically ranging from 100MB to 200MB in size
5. Solution: A Document Service was created to streamline document generation, supporting both asynchronous and synchronous report generation. Various priority-based SQS queues were set up, accommodating
7. different types of consumers. This enhancement allows for the creation of large files, including CSVs with 10 lakh rows and files up to 500-600 MB in size.
8. Tools Used: Fast API, MySQL, SQS Ques
9. Coding Design Patterns: Command Design Pattern
10. Problem 3: Extending the timeout on nginx servers to resolve internal service issues later caused a system bottleneck
11. Solution: To resolve this, worked with the DevOps Team to set up Kafka, configured topics, and requested data in smaller segments from the service. Each service then produced messages on these topics, with consumers in place to receive messages concurrently. This coordinated approach successfully solved the problem for the team
12. Tools Used: Fast API, Kafka, MongoDB
13. Coding Design Patterns: Command Design Pattern
14. Problem 4: DB Connection Lost And API Optimisation
15. Solution: The query's performance is quite sluggish, taking 2 to 3 minutes, which is unacceptably slow for an API. To address this issue, employed Python hash mapping to optimize the query. Also eliminated the need for loops and removed left joins from the query. Additionally, improved connection handling by implementing a singleton class and creating database connections at the DAO level.
16. Tools Used: MySQL & Python
