SENIOR
a senior Ruby/RoR engineer with solid knowledge of fintech Algorithms
I have been working in the IT filed since 2014.
I have a significant experience of development on Ruby back-end side (monolithic
application/WEB APIs using related frameworks like Rails, Sinatra with different
architecture approaches such as PORO, Trailblazer). Also, I’ve worked with front-end
part as well (plain HTML+CSS+JS stack/different pre-processors, familiar with
Vue.js/Nuxt).
I’m aware of main principles of OOP and their usage in programming process, widely
use SOLID principles, design patterns (if there is a possibility and necessity), different
interesting reasonable approaches.
I have experience of development in team and familiar with Agile, Scrum, Kanban.
I’m a hardworking, collaborative and highly motivated person, always keen on
something new.
