I love simple and clear code so I don't have to explain it. I try to solve the problem in the simplest and fastest way so that the solution does not create new issues in the future. I quickly learn new tools and technologies. I can work remotely. I'm not afraid to ask questions if something is unclear and ask for help if necessary.
I have a bachelor's degree and a master's degree in Computer Science.
I am looking for a friendly team for comfortable work.
I will be glad to communicate or receive feedback from you.
Good day.

I want to work in a startup or product company as a full-stack or backend developer with the possibility to lead a team as an Engineering manager. Always eager to learn both technically and personally.
I have worked on different types of projects from small startups to enterprise-like companies like Toptal.
I will describe the most interesting projects I worked on below:
TicketCo - ticket booking platform - events made easy
TicketCo app motto was “events made easy”. So it focused on organizer needs.
I started to develop organizer features, such as event reports and reports for taxing & invoicing, running & tracking marketing campaigns, etc.
Events had different scales from small to huge festivals. As a result, we had to scale.
We implemented queueing and later auto-scaling for our web services
From the client side, I developed 1st mobile version of the site.
We also developed mobile application.
I was responsible for API for mobile applications. They needed optimizations as well when a lot of data is sent to mobile. So, we decided to use PostgreSQL capabilities of generating JSON which improved performance a lot.
Local Sports Network - sports video streaming
I started as a solo Full-Stack developer with 1-1 communication with CTO & CEO.
Later, when the team grew became an Engineering Manager leading a team.
We were working in sprints by delivering valuable features every 1-2 weeks in an Agile/SCRUM way including planning features with business, grooming tickets with engineering & running retrospectives afterwards.
Toptal (core team full-stack developer)
In the Screening Ops team, I worked to simplify the life of the interviewer and reduce their workload. I was leading different projects touching both frontend & backend parts.
As a member of CMS team I extracted part of monolith into a separate service to simplify deployment & enable content editors to update content easier and in more user-friendly way.
- lead a team of engineers and build Agile processes between product, designers & engineers
- lead a project which generated ~10MLN$ revenue

For gem 'devise' I wrote custom part which works with requests which is in format JSON. Before to log in user, this part sends its own request to external server to check if this user already signed in there with this credentials. My server encodes credentials with public key and Base64 and then proceed further with answer. This mean I can work with HTTP protocol, to set its Headers, Path and params.
