WORK EXPERIENCE
WorkHQ
Front-end Developer - Jun 2024 - Feb 2025
SaaS platform for recruiters that consolidates multiple hiring tools into a single solution. The platform aims
to streamline the hiring process by replacing multiple costly and complex systems with an all-in-one,
affordable solution.
My contribution: Joining a production-ready project with complex pages, I focused on enhancing existing
features, adding new ones, refactoring, and optimizing rendering. The most challenging parts were improving
data flow and handling various user behavior scenarios to maintain UI consistency. I also contributed to a
Chrome extension and a backend application.

SaaS startup application (NDA)
Front-end Developer - Mar 2023 - May 2024
SaaS application for large companies, which provides the ability to conveniently control planned employee
salary increases using large interactive tables; control the general and local budgets of the company; provide
extensive statistics on salaries and budgets using various charts.
My contribution: I worked on large interactive tables with hundreds of rows and 20–30 columns, featuring
filtering, sorting, DnD, and nested rows. Each row had interdependent inputs (e.g., value percent), select
fields, and dynamic aggregation. To solve performance issues from excessive re-renders, I built an optimized
system using Redux to update only the necessary cells. I also developed various charts to display statistical
data.

City Plumbing “Bathrooms” eCommerce Platform
Front-end Developer - Aug 2021 — Mar 2023
The platform specializes in selling complete bathroom design solutions, and individual bathroom products,
and offers general product advertising. It is designed to provide a seamless, engaging shopping experience,
focusing on high-quality visuals and user-friendly functionalities.
My contribution: I created a custom solution for an infinite slider component without using any third-party
libraries. Created a custom components parser that can render the entire page based on the data received
from the API (for this purpose our team implemented a page constructor based on the CMS Contentful).
Participated in the creation of our internal npm packages - CSS classes library (tailwind-like), components,
and icons libraries. All of them have been used in many other projects.

Crypto Launchpad TGdao 1.0
Front-end Developer - Sep 2020 — Aug 2021
The platform for financing crypto projects and buying tokens. The application consisted of an informational
landing page and a dashboard for registered users.
My contribution: As a single FE-developer I created a full-fledged react application for replacing a simple
lading page. Integrated the dashboard with API to display real-time data, added authentication using
Metamask, and implemented a mobile version design.
