Backend DeveloperIT

I am a highly motivated software engineer specializing in backend development, with 4 years of hands-on experience in the field since 2021. Throughout my career, I’ve had the opportunity to lead and participate in vendor migration processes, which has given me a broad perspective on adapting technologies and integrating legacy systems with new solutions. My professional journey includes working with Java on various large-scale projects using microsservices, where I applied best development practices and enhanced the performance of critical systems. I have a strong affinity for agile methodologies, especially Kanban, and have effectively collaborated with cross-functional teams to deliver high-quality solutions within challenging deadlines. Versatility is one of my key strengths. While I have a solid foundation in Java and Spring, I’ve also quickly adapted to new technologies and environments. I am proficient in working with both relational databases like PostgreSQL, Oracle, and MySQL, as well as non-relational databases like MongoDB and DynamoDB. Additionally, I have experience with asynchronous communication using Kafka and RabbitMQ. I am also familiar with tools like Gradle for building projects and JUnit for testing. Always seeking the most efficient and scalable solution, I ensure that every project I work on is optimized for performance and reliability. I am passionate about technology and constantly seek challenges that allow me to grow and evolve as a professional.
