I approach code reviews as a way to improve code quality, maintain consistency, and ensure data processing. I focus on reliability, performance, security, and adherence to best practices rather than just syntax issues. So, for example, in one review, I noticed a section where the database calls were being made repeatedly inside a loop in an API endpoint. I pointed it out and suggested refactoring it to the batch the queries and use more efficient data access patterns. The change significantly improved the endpoint's performance and reduced unnecessary database load, making the system more efficient and scalable.
At one point, we experienced performance bottlenecks during peak periods where order and payment processing became quite slow. So I optimized the queries and refactored critical parts of the code using, of the backend code using Dapper, right, since Dapper was more, is more or tends to be more faster in certain cases. So that was what I did. Thank you.
One example is the food ordering and wallet management system I worked on. I was responsible for designing and developing the backend APIs using C# and ASP.NET Core, as well as structuring the database with SQL and EF Core. A key improvement I made was optimizing how orders and payments were processed. Initially, some operations were tightly coupled and caused delays during peak usage. I refactored some parts of the system into more efficient service layers and improved SQL performance using Dapper for critical operations. This reduced order processing time and improved overall system responsiveness, especially during high-traffic periods. It also made the system more reliable, easier to scale, which helped streamline daily operations for both users and administrators. So the tools I used, I used, I functioned, like I said, as the sole backend developer. I used C# for C#, I used ASP.NET Core for the framework. I used RESTful APIs for the APIs. I used SQL for the database. I used EF Core and Dapper for the ORM. I used lucid charts for designing the database and the relationships with the various entities. So those are the things I used. I used Git for version control. So those were the things I used. While the front-end developer used Vue.js for consuming the APIs. Thank you.
