I have a master's degree of Computer Engineering (Kharkiv National University of Radioelectronics). In most of the projects in which I participated, I was in the role of a full stack developer. (React+Node.js). Also, in some of the projects I performed the work of a technical lead and worked on the project architecture, established work processes and team communications, created and distributed tasks, and did code reviews. I also have successful experience working with interns as their mentor.
As a developer, I prefer to work with the React+Node stack, but at the same time I am open to everything new.I like to work with cloud technologies and have relevant experience (GCP, Firebase, AWS), also enjoy working with topography, maps, physical devices and related functionality.

I have deep knowledge of how to develop an effective and secure backend using FastAPI, how to create an optimized architecture for PostgreSQL and write effective queries to it. I also have experience working with microservice architectures and setting up interactions between services using Kafka or RabbitMQ.
My 3 years of experience in the frontend allowed me to get a good handle on React and Next and, with their help, create an interface from scratch or integrate new components into an existing interface.
I like to develop something new, take initiative and set high goals for myself, and this gave me the opportunity to take the role of Team Lead, which became a big challenge for me, but despite this I led my team for more than a year and we successfully closed 3 projects.
