ARMEN SARGSYAN Java/Kotlin software engineer CONTACTS PROFILE SUMMARY WORK EXPERIENCE - 9 YEARS 👨‍💻I am a software engineer specializing in Java and Kotlin. Linkedin EDUCATION- NATIONAL POLYTECHNIC UNIVERSITY OF ARMENIA, GYUMRI BRANCH Master of Computer Science - NATIONAL POLYTECHNIC UNIVERSITY OF ARMENIA, GYUMRI BRANCH Bachelor of Applied mathematics LANGUAGES English : fluent B2 Russian: fluent B2 Armenian: native With a deep understanding of software development principles, I strive to create reliable and scalable solutions that meet business needs. I believe in the power of clear communication with both team members and stakeholders to ensure alignment and effective goal achievement. My goal is to continuously learn and adapt to new technologies and trends, which enables me to work effectively on any project. 🚀 DevOps I believe that current trends require developers not only to know classic backend technologies, but also to have additional knowledge. That’s why I started learning DevOps. I really enjoy this field, and I think it complements Java and Kotlin development perfectly. I have worked with several architectural patterns in DevOps, such as containerization using Docker and orchestration with Kubernetes. 🤖🦾 AI Technologies In addition, the modern era demands not only strong technical skills but also the right approach to using AI technologies. I believe we are already witnessing a process of filtering — where more and more repetitive and routine tasks are being automated. Thanks to AI, many tasks can now be handled by smaller, more efficient teams. It is important for engineers to adapt, stay up to date, and actively integrate AI tools into their workflows in order to remain competitive and deliver greater value.
