Vadim Popkov

I am developing an analytical service for investors.

As a result of my work:

• Implemented feature-based approach to application organization - storing files belonging to only one feature in one place, unloaded the folder with all application components, separated reusable components → accelerated development
• Increased load speed by an average of 2.4x (LCP was 8.4, became 3.5) through lazy loading of scripts and images → improved user experience, improved SEO
• Fixed low performance of application tables using component memoization and re-render optimization → improved user experience
• Optimized form handling, significantly improving user input accuracy and reducing bugs by integrating React Hook Form → smoother and more intuitive user experience

Maintained a legacy application for managing an auto repair shop shop-ware.com on Backbone.js. Gained experience in debugging and refactoring complex code, writing e2e tests (Playwright), as well as experience working with React (part of the application was on React).
