Hi there.
I just read your posting carefully.
As a senior React.Js developer, I have ability to develop maintainable, secure and expandable web frontend.
I've been dedicated in web development over 6 years and mainly focusing on large and complex React Frontend architecture building.
I have deep understanding in React hook and redux and have already deployed many projects successfully.
For backend integration, I'm mostly using Restful API or GraphQL and working well with backend engineers.
With my experience in React, I can build powerful, fast and reactive web pages with amazing user experiences by leveraging the power of javascript with ease.
As you can see, I have full ability to work on your project and I will do my best for long-term cooperation with you.
Also, when working on a new project, I like to talk to my clients so that I can have a clear understanding of their needs and vision of the project.
Please feel free to send me a message at any time. Thank you for reading my proposal.
Best regards.
