Our mission at Art vs War is to create a platform where displaced artists can showcase their work and receive support for their talents. The ongoing conflict in Ukraine has created a challenging environment for many artists, and we are proud to provide a platform that allows them to share their work with the world.

Java Developer
I had the opportunity to work with a variety of technologies. For example, I used Spring Boot and Spring MVC to develop a web-based HR management system, which included features such as employee profiles, time tracking, and performance evaluations. I also used Spring Security to implement user authentication and authorization, ensuring that only authorized users could access sensitive information. In addition, I developed a REST API using Spring Boot and Hibernate, which allowed for easy integration with other systems. I also gained experience with unit testing and debugging to ensure high software quality.

Developed a scalable and maintainable Java application using Spring Boot framework that reduced processing time by 30%. Created an efficient data access layer using Hibernate ORM that improved database performance and reduced query response time by 50%. Participated in Agile software development process and delivered new features on time and within budget. Collaborated with UX designers and QA engineers to ensure a seamless user experience and high software quality. Designed and implemented RESTful APIs using the Spring Framework to enhance the usability of a client's software platform.
