Senior full-stack React-Python engineer with Blockchain experience
I have 5 years of experience in software development for commercial projects. My main responsibilities were requirements analysis, writing programming code (including the basic architecture of the project), fixing bugs, and investigating new technologies to implement tasks that go beyond the standard requirements (for example, collecting token data using open graphs and other resources with only the token address, or processing photos using software code to make them look like bills). I am experienced with databases (MySQL, PostgreSQL, MongoDB), and hi-load systems with scaling and caching, have a good understanding of OOP, REST, and MVC.
