I joined the team responsible for evolving the shopping department's backend services. These services are a part of a big project. The project is a marketplace and price comparison platform. A list of some technologies that I used while working on this project: PHP, Symfony, Doctrine, MySQL, SQL, Git, Redis, etc.

I developed and launched a new backend service. It served millions of registered users and handled millions of events per day. I implemented external API methods for web and mobile clients, an internal API for the CRM system, business logic, and CLI. I proceeded to maintain and evolve this service. I fixed bugs, improved performance, added new features, and participated in code reviews. Technologies : PHP8, Symfony 5, Docker, Doctrine ORM, Codeception, RabbitMQ, PostgreSQL, SQL, Swagger, Git, etc.

I maintained and evolved a large legacy SaaS CRM system with a monolithic architecture. I added new features and changed a lot of business logic. For example, I implemented API methods for the import and export of data. I fixed bugs, improved performance, and participated in code reviews. Backend: PHP 7, Yii framework, PHPUnit, MySQL and MongoDB , SQL, Git, Docker, RabbitMQ, and Redis. Frontend: JavaScript, jQuery, AJAX, HTML, CSS, and Bootstrap.
