I developed implementations for the dashboards of the administrative and accounting teams of the company. At the same time, I worked with data, looking for ways to optimize the company's resources. My most important achievements were implementing CI/CD with Jenkins, improving SQL query performance in PostgreSQL by 53%, and enhancing the project's abstraction level. I led a small team of 3 developers, and we managed to save the company up to 32% in costs by utilizing the data and information we presented.
