Years of experience: 4

Designed a tool for concurrent split testing which made it possible to conduct A/B tests by several teams at the same time without affecting each one’s results. The solution allows to annually conduct 3 times more A/B tests and is currently used by 3 development teams.

Improved CMS main page average load speed by 83% (from 1.1 to 0.6 seconds) by optimizing SQL queries, code profiling and splitting the single HTTP request into multiple requests to load the data
concurrently.
I'm a Software Engineer with almost 4 years of commercial experience. Have a strong engineering background with a Bachelor's degree in Computer Science from Kyiv Taras Shevchenko National University. 
Interested in backend/infrastructure problems and distributed/data-intensive applications.

The current project is a leading E-commerce platform in Ukraine, also available in other countries. It’s a high load, data-intensive distributed system that handles 10 000 RPS (total peak load) and has multiple databases of several TB in size. The project uses a custom infrastructure, deployed across several datacenters in Ukraine and other countries with k8s and Openstack.

My responsibilities included:
- Breaking down the existing monolithic application into microservices;
- Re-designing the customer reviews ecosystem both by extensive refactoring and implementing the new functionality;
- Managing the existing large legacy codebase and re-engineering it into a fault-tolerant, maintainable system;
- Providing performance optimizations for the most crucial parts of the system;
- Conducting technical interviews;

Although it's not my core competence, I have little experience in frontend development with JS/TS and React. Sometimes I also dealt with deploying the results of my work into the production environment using Docker and Kubernetes.
I expect to work with mature and strong Engineering team.
Not interested in betting or gambling services.
