Experience

viaSocket.com

http://viasocket.com
A SaaS web application allowing users to build a web services-based automation solution triggered by a webhook. I built the first Rails monolith version from scratch, then split it into separate Rails API and Angular front-end application projects, allowing the client to use team expertise better and improving velocity. Then, I optimized the back end by adding asynchronous flow steps support and support for workflow steps' cycles and conditions.

Kroogi

An innovative platform for artists in music, literature, and other platforms and their fans with multiple payment models for content, including pay-what-you-want, minimum price, and crowdfunding. I worked on the platform. It was a large project with around 100,000 active registered users and many guest visitors. My responsibilities involved full-stack application development and support, site infrastructure maintenance, engineering team leading, and hiring new engineers.

Enterprise Document Management Product

Served as the primary contributor to building the front end and a framework of front-end components.

I created a comprehensive E2E testing workflow using Selenium, CircleCI, and Docker. I also built a multiplatform, Electron-based desktop application similar to Dropbox as a part of this product.
