I’m expert in Web programming with 30+ years of experience. I always focused on implementing the best engineering practices to optimize and automate processes and increase efficiency. My goal as a programmer — to automate everything as much as possible, implementing intuitive and friendly interfaces and ways of communication between humans and machines. I believe that humans should do only creative work, the routine can be done by programs and robots. I strive to complete everything ever started, not dropping on half way. Autonomous and communicative, always very proactive.
