Angular 5 to Latest Version Migration -- 2

I'm looking for an expert in Angular to assist with the migration of my application from version 5 to the latest version. During this process, I would like to incorporate some minor feature updates, specifically the addition of new UI components. It's crucial that we maintain the performance speed of the application during the migration, as this is one of the most important aspects of the current application.

Ideal Skills:
- Proficient in Angular (especially versions 5 and latest)
- Experience with UI component integration
- Strong understanding of application performance optimization
- Knowledge of third-party integrations in Angular

The focus of this project is:
- Migrating the application without adding significant new features
- Retaining and optimizing the performance speed
- Incorporating new UI components into the migration process.

Please reach out if you have the relevant experience and skills to help with this project.
