As a leader, I have had the opportunity to build a team from scratch, define the right processes, and drive the team to incredible performance and successful outcomes for every assigned project.
I consider myself results-oriented, proactive, and always eager to explore new technologies and approaches. One of my main strengths is the ability to overcome unexpected issues as quickly as possible. I don't have preferred tasks or assignments; I enjoy solving problems, whether they come from engineering, product requirements, or management.

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

DIRECT CONTRACT ONLY
+ ruby / RoR / aws
+ stable team, stable project
+ mature teammates that can handle work and joke
- more than 3 hours of zoom per week, or if you want me to fix it. (Oh believe me I could and I will :)
- frontend would be a bummer, it's complicated enough to have it's own well skilled and focused folks on it
- bad work/life balance in the team and overtime expectations
- proprietary languages/frameworks
- weird stuff like gitlab, minitest instead of rspec, redmine instead of jira. Convention over configuration for life!
