Employment
Experience
- Teramindhttps://www.teramind.co
Teramind is a top-rated cloud platform for insider threat prevention and workforce productivity optimization, top-rated by Gartner, PC Magazine, and others. As a system and web developer, I focused mainly on the hidden monitoring agent and intelligent web dashboard.

The mission of this portal is to make business in Russia more transparent while helping entrepreneurs manage their risks and conduct market research. The portal aggregates open data from government sources about all companies in Russia, including:
- Address, tax ID, and other registration data
- Financial statements
- Detailed data about owners and their relationships
- Lawsuits
- Contracts
- Trademarks
To access a detailed profile of a specific Russian company, you just need to enter some information into the search field, such as the company name or tax ID. The portal is written in JavaScript on top of Node.js and takes advantage of the Elasticsearch engine. The front end is built with Webpack.
This is an independent project, where I perform as the sole developer, designer, and SEO manager. The portal serves around 2,500 users per day. - DigiSignerhttp://www.digisigner.com
DigiSigner is an electronic signature service that users love. It's an Angular-based application that allows you to sign documents remotely and paperlessly. The main application workflow includes uploading PDF documents, marking up documents, creating fields with some pre-entered data such as the current date, and sending links to signers. The service is highly flexible and configurable with a beautiful, modern UI. I completely rewrote the old version, which had limited functionality, was not mobile-friendly, and was implemented mostly on jQuery.
