Опыт работы:
I am a Front-End Developer with 4 years of experience, primarily focused on building React Single Page Applications. In the last 3 years, I've been using TypeScript to enhance my development projects. My skills include working with Redux (Thunk and Saga), React Query, and managing projects without a store.
I'm experienced in collaborating with designers, back-end developers, and QA teams, ensuring smooth and successful project execution.

I adapt quickly and am always eager to learn new technologies to contribute effectively to my projects.

Дополнительно:
Project Development from Scratch to Production
Successfully led the front-end development of a project from inception to production. This involved meticulous planning, development, and testing to ensure a seamless launch.
Performance Optimization and UX Enhancement
Achieved a significant improvement in application performance by refactoring pages and optimizing animations. This enhancement increased the frame rate from 10 fps to a smooth 60 fps, markedly improving user experience and resolving animation bugs.
Efficient Data Processing Algorithm
Developed and implemented an algorithm for processing approximately 20,000 objects, which resulted in a 2.5 times faster download and rendering of information. This innovation greatly enhanced UI smoothness and user-friendliness.
