About me

Software Engineer with 5+ years of hands-on experience. Passionate for automation of the Software Development pipeline. Believe that DevOps is more than tools nevertheless tools are crucial. Making developers' life easier.

Personally, I thrive in an international, collaborative environment working with like-minded professionals, bright and fun folks, in a fast-growing tech company.

There are a few professional topics I am interested in, hence deepen my research under post-grad studies, doing keynote speeches at conferences, issuing publications.

CS.Money

Platform Team Lead (Mar 2022 - Now)

As a lead of Platform team in CS.Money I guide my team on releasing deliveries aimed at DevEx improvement. This is achieved by creating and maintaining transparent processes targeting developers.

My team under my leadership has fully completed the migration of services to Kubernetes and AWS.

• Decreased infrastructure costs by optimizing instances usage and decreasing egress network traffic
• Introduced ZeroTrust for securing internal systems and development environments
• Promoted Everything as Code approach

Platform Engineer (Jul 2021 - Mar 2022)

As a Platform Engineer in CS.Money I increased maintainability of pipelines templates and services deployments. I started migrating services from bunch of instances with docker-compose to Kubernetes cluster and to fully managed Amazon Web Services. All of the resources were created with Pulumi IaC solution that allowed to use real programming language instead of markup language.

The best decision was to use Pulumi instead of Werf tool for deployment to k8s. To ease the deployment process of new services and the maintenance process of already deployed ones, some libraries were written. All of them were written in TypeScript programming language due to amount of code and better readability than Go language.

Industrial Systems for streaming data processing

Team Lead (Oct 2019 - Jul 2021)

Responsible for the Software Development Life Circle of multiple products in Industrial Systems for Streaming Data Processing Laboratory.

• Managed a DevOps team
• Consulted Develpment teams on architectural solutions
• Maintained on-prem, edge and cloud infrastructure

Lead Developer (Feb 2018 - Oct 2019)

A research lab at Peter the Great St.Petersburg University that conducts original research and performs commercial developments in related fields. The projects ranged from the development of an information system for owners, investors and residents of investment hotels to development of a software for behavioral strategies of mouse models analyzis.

A lot of projects were somehow related to artificial intelligence and computer vision. One of such projects was a software for disguised face detection on a video stream. Initially, that project was intended for banks, nevertheless, it continued as a research project.

R&D Projects

Huawei (May 2021 - Dec 2021)

A collaborative project between Huawei and Peter the Great St.Petersburg Polytechnic University. The goal was to develop a tool that will allow a developer to minimize the amount of test suites without impact on coverage. During the project, the prototype as a PoC was developed,research of different test suite minimization techniques was conducted. Java programming language was used for everything. As a result of the project, an expandable minimization engine that can detect redundant tests was provided. A wide range of existing approaches and techniques was analyzed.

Siemens (Jan 2017 - Jun 2018)

A collaborative project between Siemens and the Peter the Great St.Petersburg Polytechnic University. The goal was to investigate the possibility of using artificial neural networks for software clone detection process. This research became a topic of master thesis. As an outcome of the project, the prototype as a PoC was developed. Two programming languages were used - Java & Python. Java was used for AST (Abstract Syntax Tree) extraction and preprocessing, while Python was used for recurrent neural network implementation and post-processing.

Also, there was a need in a lot of data for training, testing and validation. Thus, besides PoC, a Mutator that allowed to generate a lot of artificial clones was also developed. This Mutator could generate all types of syntactical clones and its output was used for efficiency measurement.
