New solution helped to find unseen bugs and fully avoid future translation issues.Implemented opt-in caching feature in the internal form library.Integrated TOTP two factor authrorization (2fa) on the frontend. Extensively covered by e2e cypress testsSignificantly improved performance of rendering markers on a map using KD-tree and clusterization.

Implemented a form builder, whose resulting form can handle both context and asynchronous validations, by using tree graph. Created its custom hook to subscribe a component to specific part of form, so the component renders only when this part changes.Built a simple polygon constructor using geometry, SVG elements and advanced techniques such as double masking. Constructed polygon is fully manipulative: each point or whole figure can be dragged.Created animated page with functionalities such as illustration, creation and deactivation of licenses. Wrote whole logic on class based services, so it is easier to test and maintain them. Covered services by unit tests, components by e2e cypress tests.
