Last 5 years I've taken part in different Web-projects with different tech stacks on the front-end as well as on the back-end. I have stronger knowledge in Front-End, have experience in development of SPA, PWA. I was developing internal tools and main products, supporting and adding new features to apps in production. In the majority of cases, it was non-trivial SPAs with rich functionality and complex business logic. Now I'm more focused on working in the Front-End
