At Videoly I was responsible for developing the core customer-facing product - Videoly Widget. Most of the time I developed the brand new widget. The initial project, written in vanilla JavaScript, was full of code couplings and tricky staff, so it was a great time for developing Sherlock's intuition. Alongside new widget development, I fixed bugs and implemented new features in the production widget, worked with the backend, videoly chrome extension, browserstack, and other parts of the Videoly project. In the end I rebuilt the widget in new stack and widget team ran it in production. 🏆

Nord Clan is a software development company that focuses its efforts on a variety of fields, such as fintech, computer vision, healthcare, CRMs, and others. I've been working on a CRM system for a company that produces electric and thermal energy, so there was a special attention to details. It was a huge project, written in React/Redux stack. The main goal of that CRM was to do detours in the factory to detect equipment quality of work, then analyze gathered data to be able to improve efficiency of the equipment and detours. There was a wide field for refactoring. I've refactored dozens of components, tables, complex charts, monstrous reducers, made several big pages and stayed alive. 🏄🏻‍♂️

IML Express is the first big company where I worked as a frontend dev. There I had the opportunity to learn from experienced professionals. I was working on an in-house fulfillment system for which I developed most of the mobile screens. Additionally, I refactored many of old components to make them simple and clean, which improved the overall performance and user experience.
