Denis Bandurin

Java Developer

Hey!

I'm Denis Bandurin from Germany.

About Me

With seven years of experience in the IT industry, I decided to transition into Java programming. I gained my initial IT experience in Russia as an administrator from 2015 to 2020 in St. Petersburg. During this time, I acquired valuable knowledge working with Unix systems and developed small applications for various tasks. I further expanded my expertise as a member of the technical staff at Oracle, where I contributed to a cloud project by testing networks and hard disk drivers. I faced the challenge of working with Python instead of Java and successfully adapted to the new language. Additionally, I regularly tested drivers with new kernels on different virtual machines.

Since the beginning of 2018, I have been actively studying backend and frontend development on my own. I have completed several courses on the JavaRush and Helsinki University platforms, enhancing my skills in these areas. This year, I focused on learning Kubernetes and Docker to strengthen my proficiency in containerization and orchestration. Currently, I am pursuing the Ultimate AWS Certified Developer Associate 2023 NEW DVA-C02 online course on Udemy. You can explore my portfolio page, which showcases projects I have developed independently.

My passion lies in professional growth as a Java Developer, both in backend and frontend development, with the ultimate goal of becoming an Architect. Drawing from my experience as a system administrator, I possess a deep understanding of DevOps features and how they can contribute to successful project outcomes. I am highly motivated to apply my knowledge in challenging projects that not only allow me to learn new technologies but also enhance my working experience.

On a personal level, I am peace-minded and patient. Team games like volleyball, photography and traveling are among my hobbies.
