Ruby Mentor. Lead QA Automation Engineer. Software Development Engineer in Test (SDET)
Great experience in Ruby, Webdriver, Cucumber and Rspec technologies.

As a QA Automation Engineer, I do my best to provide to customers a product with the perfect quality for more than 10 years. I am focused to think as a client to observe what exactly they expect from a product. I have been an essential part of the best developer teams such as Toptal and Upwork. We delivered 100% tested and consistent code quality. Based on my strong Ruby skills I have been providing architect solutions to our test frameworks permanently.

As a Ruby mentor, I share my passion and knowledge with everyone who is interested to learn this great and human-oriented language. To be successful in Ruby, you need to know its deep object model and feel confident in the world of meta-programming magic. Last years, I brought Ruby light to 5 different groups of students and I am not going to stop doing this.

Also, I am an activist and I believe in an equality for everyone. I always try to popularize these values in companies where I work. I realized that most successful developer teams are managed by horizontal principles. Another important point for me is an ability to work in a company that creates useful and ethical things (and that's the reason I don't see myself in an advertisement, military sector etc).

      Edward Woodcock | Founder of Dinghy

      Really great to work with. Brought lots of good ideas to the team and a lot of expertise which was executed very well. Lots of communication about work to date and intentions. Would happily hire again.

      Andrew Emelianenko | Product Architect at Dinghy

      I was absolutely happy to work with Alex. I worked with himbefore. So when we opened the Lead QA Automation position,Alex was the first person in my list. He is a professional of thehighest class, me and team were absolutely satisfied with his job.I hope we'll work together again in the future.

      Anton Uhlenko | Release Manager at BETLAB

      The Dynamic Ruby course, delivered by Alexander, proved to be very useful for me. Alexander is a good professional and excellent teacher. The material was given gradually and with a lot of examples, that made it comprehensible and enabled me to memorize and learn it well.

      Kate Batsenko | Head of Education at GoIT:

      In summer 2015 Alex has delivered series of Master Classes & Workshops dedicated to Ruby for GoIT students and alumni. He composed it of two parts - "Ruby in general" (providing a broad view of Ruby as a programming language, with very useful practical examples and metaprogramming) and "Automation Testing in Ruby" (using cucumber + watir-webdriver technologies). The students and alumni, who are developers and QA engineers as well, and are interested in studying Ruby for automation, enjoyed these workshops very much. They especially noted the intense material and its applicability, and Alex's undoubted talent of a teacher / speaker. Thanks again and hope for further co-operation!

      Arkadiy Zabazhanov | Senior RoR developer at Toptal

      Alex is an outstanding engineer and QA. It seems like he got a sixth sense on bugs and blind spots revealing. Along with a great personality, he is proactive and passionate QA.

      Konstantin Govorukha | QA Automation Team Lead at Adyax:

      Alex has a good experience in automated testing. He is a well productive person. During my work with Alex I noted often he worked faster than me and I could assign to him tasks which should be done in short time period. Also he learned new knowledge pretty quickly so it was not a problem to give absolutely new unknown task to Alex. I think Alex is a person who will learn new technologies during all the time. I was glad to work with Alex and I recomend him to other people.
