Bid infrastructure department.I'm in the team which is doing an Intelligent Load Balancer.That smart server is able to keep more than 1.5K requests per one core per second.Here we focus on the performance tasks and doing hard work to bring new features andkeep performance at least at the same level as it is on the previous version.We are also building CI/CD pipeline which allows us to keep development velocity, high quality, and delivery speed.It's build over Jenkins CI and includes some interesting and non-standard stages like "profiles comparison" among the standard tasks.Here we're following the "Configuration as a code" approachand also do not couple the main functionality with the Jenkins Groovy.That allow us to use same configuration across all the host machines. Which is very convenient.Another focus of our team is so called "Performance-Playground" component.That is set of the configurations which are orchestrated by Terraform.That allows us to set up a dev mini-cluster with the prod environmentand replay the any slice of the live traffic through the development branch; collect profiles, metrics and compare them with the prod values.Besides that, we are working with the other teams to insert the load balancer in their existing testing frameworks.The main challenge here is that current framework is a mature project with the huge codebase. Much complex logic has already built over that framework and many more tests are written. The task is to migrate all without affecting the current processes.It sounds like "It's just a proxy server, you only need to change the system ports". Sounds good, but there are some nuances :)

BIDSWITCH departmentLed the migration from the monolith to microservice architecture. Achievements:- Designed and implemented ApiGateway with AuthZ inside it. Besides that, we added support of the plugging subsystem. It allows other teams to independently extend the functionality of the API gateway. In addition, we implemented the protocol validation component, based on the JSONSchema specification. That allows us to separate API versioning management and services development. - Led the development of the framework for building micro-services while moving from monolith to microservices architecture.To archive that we use the next common practices: - Agile methodology, mostly Scrum with some modifications according to the team's needs - Test-Driven Development - CI/CD pipelines - Dockerization Moving to the service-oriented architecture allows us to split monolith with a minimal impact on the current functionality. That approach was chosen as a safe way to refactor the system.Technology stack:Python3, Django, Django Rest Framework, Postgres, Jenkins, Docker

UI departmentLed the development to create a "lego"-like system. The system is able to take an OpenAPI based specification and configure itself in runtime: both on backend and frontend sides.In the scope of this project we got the goal to develop a solution which could meet the following criteria: * create a framework to use in a different team as a constructor for building the projects * it encapsulates AdTech domain model and base relations between the entities * establishing of the "best-seller" project goes with the configuration file only * basic project customization, such as management of entities' relations, features management, subsystem management could be done over the configuration fileFor these purposes we designed a framework over Django-rest-framework with the next characteristics: * follows SOLID principles * based on Domain Driven Design approach * operates with loosely coupled components * developed with respect to TDD practices * feature-based specifications * schema-based project customizationIn addition to the main system, we designed the CI/CD pipeline based on dockerization and Jenkins CI.It allows us to have a ready to use the system by a single commit in the central repository. Ultimately, all that allows us to rapidly deliver new projects with configurable entities structure(database schema) and feature set. That configuration file has OpenAPI compatible specification and both on backend and frontend configure itself on runtime independently.Delivered 70+ projects

I was engaged in developing a VoIP billing software solution specifically tailored for small and medium-sized businesses. My role involved tasks related to enhancing the billing management system and addressing software bugs. The most challenging and rewarding aspect of this project was the integration with Asterisk software. Our team successfully developed an Asterisk extension that enabled us to effectively manage VoIP traffic between the Asterisk platform and Mera Softswitch.

I was actively involved in developing and implementing a document management system and associated workflows. As a key contributor, I was responsible for enhancing inter-component communication within the system. Additionally, I played a crucial role in developing and maintaining an SFTP client seamlessly integrated into the system.
