Jobayer is very professional and smart. His English is very good, too. He understands projects and doesn't mind making corrections when necessary. I highly recommend him. He has no problem with Svelte, React, Github, CSS or HTML and is very responsive.

Jobayer was very easy to work with and he understood my complex needs. I would definitely work with him again. He discussed with me the pros and cons of Svelte and React and helped me implement a real fix to my project.
