Artur Poliachenko

Artur Poliachenko Technical Lead Developer Summary of Qualifications I have more than 9-year production experience in development of web-oriented applications within Java technology stack. I started my career as PHP developer for social educational platform. Later I joined team of passionate code geeks as a Java software developer struggling to create outstanding products with absolute devotion to details. I was responsible for implementation of backend components, integration with various third-party systems and eventually participated in architectural and technological decision making. My usual tasks ranged from pure backend business logic or data storage level components to rich responsive frontend modules and layout schemes. I gained deep and thorough understanding of OOD design and development practices, adopted proper design pattern usage techniques and learned to consider code maintainability and efficiency daily. I am capable of quick learning and have profound technical and algorithmic background. Ten years of professional education helped me to develop strong analytical skills and provided me with a variety of approaches to problem formalization, decomposition and solution. I greatly enjoy working in highly skilled teams due to the fact, that I can get a share of experience from other team members, which I find exceptionally beneficial. I am constantly seeking for opportunities to solve challenging and technically demanding tasks, develop myself to a greater extent and move beyond my current limits.
