What key projects can you highlight at your current workplace? What are you proud of?

At my current job, the key projects were:

• Development of a scalable API for e-commerce: Created a high-performance REST API in PHP using Symfony, ensuring stability under high loads and integration with external payment systems.

• Database optimization and caching: Implemented effective indexes and used Redis for caching frequently requested data, reducing system response time by 40%.

• Refactoring and implementing CI/CD: Refactored outdated code, improved test coverage, set up automated build and deployment, which increased reliability and speed of releasing new versions.

I am proud that my solutions significantly increased the product's performance and stability, as well as improved development and support processes.
