Position: Ruby on Rails Developer
Category: Ruby
English level: upper
Years of experience: 9


As a Ruby developer with 9 years of experience working with Ruby, PostgreSQL, and Sidekiq, I have had the opportunity to work on a variety of projects and gain extensive knowledge in these technologies. One memorable experience that stands out is my involvement in developing a large-scale e-commerce platform.

In this project, I was part of a cross-functional team responsible for building and maintaining the back-end infrastructure. My role primarily focused on developing and optimizing the Ruby codebase, managing the PostgreSQL database, and leveraging Sidekiq for background job processing.

To begin, we utilized Ruby on Rails as the framework for our application, taking advantage of its MVC architecture and convention-over-configuration principles. My experience with Rails allowed me to quickly adapt to the project's codebase and contribute effectively from the start.

Working closely with the front-end team, we collaborated on designing efficient APIs to support the various features of the e-commerce platform, such as product listings, shopping cart management, and order processing. I implemented these APIs using Ruby and ensured their seamless integration with the existing infrastructure.

PostgreSQL served as the backbone for our database management system. With my deep understanding of SQL and PostgreSQL's advanced features, I optimized queries, created database indexes, and implemented data partitioning strategies to handle the substantial volume of data generated by the platform. This not only improved the application's overall performance but also allowed for faster data retrieval and reduced latency.

One critical aspect of the project was ensuring a smooth user experience while handling resource-intensive tasks. To achieve this, we employed Sidekiq, a background processing library for Ruby, to manage asynchronous job execution. I designed and implemented Sidekiq workers for tasks such as image processing, order notifications, and email delivery. This approach greatly enhanced the responsiveness of the platform, allowing users to perform multiple tasks simultaneously without any noticeable delays.

Throughout the project, I actively participated in code reviews, sharing my expertise with the team and providing constructive feedback. This collaborative environment fostered continuous improvement, ensuring the delivery of high-quality code and maintaining codebase integrity.
