In my previous role, I worked on a web application designed to automate and manage business processes for small and medium-sized enterprises. This no-code platform facilitates digitalization and customization of various business operations.
A similar technology stack was used for these projects: Java 11, Spring (Boot, Data, Security), Hibernate, PostgreSQL, Liquibase, JUnit, Mockito, Maven, Swagger, etc.
In addition, I have ten years of experience as a data analyst in a government agency, where I specialized in automating data processing, report generation, and analyzing commodity and cash flows.
I am seeking a Java Developer position where I can leverage my skills and expertise to contribute to interesting projects and collaborate with a dynamic team. I aspire to work in an environment that fosters continuous learning, encourages creative problem-solving, and offers opportunities for career growth.
Not Looking For:
I am not interested in roles that are heavily focused on non-technical tasks, lack opportunities for professional development, or have an overly stressful work environment.
