When I joined the team, unit tests were few and frequently failed. Since then, I have played a leading role in improving code quality, which has increased coverage by 30%.

Smart Contact Form Feature
Reducing the number of customer tickets created in the CRM application through generative AI is one of the company's key objectives for 2025. In this context, I opted for a simple and robust architecture, based on a Domain-Driven Design (DDD) approach, using value objects rather than primitive types. I also applied SOLID principles to achieve clean code. To leave nothing to chance, I also maximized code coverage (> 90%) through unit and integration tests.
