Full-stack Developer

May 2024 – Present · 2 yrs · Ottawa, Ontario, Canada · On-site

Worked on an application that connects smart rear-view mirrors with a mobile app to the cloud and allows users to control their home devices from the car. Once a user presses a button on the mirror, the app sends a signal to the cloud, which then sends a request to the smart home device connected through Alexa, Google Home, SmartThings, or Home Assistant. For example, the user can open the garage door, turn on the lights or the heating system from the car.

Drop domain

Software Engineer

Mar 2016 – Oct 2022 · 6 yrs 7 mos · Batumi, Ajaria, Georgia

I developed a system from scratch that collects and analyzes information about all domain names in the .ru zone (about 5,000,000 domain names).
The system consists of 3 parts:
The first part (parsers) consists of several parsers that collect information about domain names from various sources (Whois, Alexa, Reg.ru, Yandex, Majestic, Megaindex, Sbis, etc.), transform it and pass data through RabbitMQ to the second module. Each service is build to run in a Docker container.
The second part (control panel) consists of a database and a web application. The database stores information about domain names and all the information collected. The web app also allows the setup and configuration of parsers, view statistics, and graphs.
The third part (business logic) contains a web application and a service. The web app sets rules for the automatic buying and selling of domain names through the API of the domain registrar Reg.ru.
The backend and parsers are built with C#, .Net 3, ASP.NET MVC, Entity Framework, SQL Server, Selenium, and RabbitMQ. Web applications utilize C#, ASP.NET MVC, Entity Framework, JavaScript, CSS, Bootstrap, and Chart.js.
