Russian FederationWhat I'm looking for
I've been building web products since May 2021, creating pixel-perfect, responsive websites from design mockups and developing React and Node.js applications and services. At GUTAX, I modified live websites, resolved bugs, built Bitrix CMS sites, developed backend and block logic, and deployed projects to hosting.
I've contributed to hackathon-winning projects including an SDK Prioritizer feedback plugin and a Report Builder built with React, Vite, TypeScript, Sass, Node.js, Laravel, and MySQL. I also work with WordPress, PHP, Next.js, Git, VPS configuration on Ubuntu, and have served as an expert judge at web development competitions.
