Hi, I'm Aleks

Aleksandr Ulanov

Senior Full Stack Engineer (Independent Contractor)

Hi there, my name is Aleksandr Ulanov, and I’m a Senior Full Stack Engineer. I started web development in 2012 and gained strong knowledge and expertise in the field over time. I’m a huge fan of Ruby programming language and I know its ecosystem pretty well. That being said I was working with Ruby, Rails, Javascript and React most of the time I’m doing web development. But I’m not being limited by Ruby and Rails, so even though I had not much time to play with Python and Go, I’m still interested in both languages and always happy, when I have a chance to acquire experience with them. I’m also writing articles related to my experience in web development, Ruby, Rails, Python, JS and everything related to those.
