I'm a professional and enthusiastic full-stack software developer with many years of experience. I have worked on projects in diverse business domains for many small firms and big corporations. I build web services and apps, websites and Android apps. I'm flexible and open minded, always enjoying an oportunity to learn something new and solve unique problems. I usually use: - Java, Ruby, JavaScript, HTML5/CSS3/SASS - Spring Boot, Rails, jQuery, Android - PostgreSQL, MongoDB, Redis - AWS, Docker, Linux, Windows A little background: Programming started as a hobby in my early childhood. Due to my analytical nature I really enjoyed time spent deepening my knowledge in software development and inner workings of various systems making myself truly undertand how they work. I learned many popular languages Java emerged as my favourite. This passion led me to study Software Engineering at the Warsaw University of Technology and quickly evolved to be my profession of choice.
