Alexey has been working as a contractor for corporate America for more than seven years. He has been able to thrive in complex scenarios, such as being the sole developer of a startup—building a product from the ground up with the CEO—or rescuing projects that were considered hopeless due to a previous developer's failure. Alexey's main specialization is building complex web services on AWS using Node.js or PHP/Laravel.
