ABOUT ME
Software Engineer
Software Engineer

I'm an experienced Full Stack Engineer / Architect specialized on design and delivery of corporate solutions with both complex Backend and Frontend.

As an Engineer, I have delivered a plenty of projects in various business domains, such as FinTech, AdTech, Marketing automation, Travel industry, Recruitment and HR, Telecommunications.

I create robust, scalable and efficient Enterprise level applications of high complexity, intended to run within both classic on-premise environments, and in popular Cloud platforms, using such popular Backend programming languages as Java, Go, Python, PHP, and Javascript/Typescript with Node.js. I have experience using popular frameworks for each of these languages, such as for example Spring (several components) and GWT for Java, Django for Python, Symfony and Laravel for PHP, Expess.js with Node.js and others. Typically nowadays the Backend I use to deliver is a number of microservices with one or more exposed APIs, most often HTTP REST. For the Frontend, I have experience creating complex Web based dashboards using popular Javascript / Typescript based solutions, such as Angular 2+, React.js, and a big variety of different libraries.

As part of architecture and design phase, I actively participate in the discussion of an upcoming solution, discovering and digging into the problem that we are trying to solve, providing you with comprehensive recommendations and coming up with a fully fledged design proposal, development phases and their estimation, as well as corresponding documentation afterwards. I also have an experience leading a small development team, providing it with an appropriate task splitting, basic engineering management, tech guidance, code reviews and support.

As a supporter of "you build, you run" philosophy, I have a practical exposure to the DevOps, setting and using the CI/CD pipeline, with an active usage of IaaC tools, such as Terraform or Ansible. I actively use Docker in all the variety of possible ways: for development, testing, deployment, and in production - as well as have Kubernetes experience.

Looking forward to working with you!

Developed several services and a highload project in the area of trading and finances from scratch. I consider Go as the best choice for services and especially highload development nowadays and keep actively using it.

Almost no web project is possible to imagine without this language. I used it widely at many projects, both at frontend (including usage of such famous frameworks and libraries as jQuery, Bootstrap and Datatables, Angular, React) and at complex backend services (Node.js, Express framework, Meteor.js)

Univoice creates mobile apps for non-standard language learning leveraging music and AI. At Univoice, I took over the backend based on Go, Node.js and Kubernetes. I revamped and significantly improved the robustness of the backend, significantly improved the CI/CD pipelines, as well as implemented a number of new features: user management API, integration with LLM APIs and many others.

Ferrum Health is a health technology company that partners with leading hospital systems to reduce the impact of medical errors, modernize quality improvement and improve patient outcomes through the use of Artificial Intelligence.
Ferrum’s next-generation platform provides hospital systems with an additional layer of quality assurance for critical decisions across the entire continuum of patient care.
Worked closely with the project providing the platform for healthcare ML apps run, as well as related user facing and other integration software. Steered the development and refactoring of several backend microservices of the company’s software solution. Significantly reworked the company's authentication and authorization basis, introducing the SSO provider and making the support for authentication over multi-node architecture.

Orison Panel is an easy-plug device which allows to store energy at home, either from grid, or solar panels. It can work either as an intelligent UPS, or be used to back feed the energy to the grid, the main purpose of which is to store when the energy is cheap (e.g. at night) and return when it's expensive. The latter process would mainly be managed by a utility company. Under the hood, the Panel has a bunch of different software modules that control all the underlying hardware and its safety, the process of charge / discharge loops in a variety of scenarios, external management, monitoring and communication with the Cloud over the internet. I have headed or participated in the development of several software modules.


The biggest engineering challenge comes along with Panel workflow, which inherently counts with a number of edge cases and scenarios to handle (e.g., operation mode based on current voltage/current, different hardware states based on their health and mutual interaction, etc.), while acting in a highly asynchronous environment. As a result, we need to continuously evaluate current context looking at a bunch of metrics, and act accordingly, always consider safety, stability and performance and take seriously all kinds of testing, as the device would be working fully autonomously and with limited computational resources.
