Hi!
I checked you need a highly proved javascript engineer for your project.
For the last 8 years, I worked on various javascript libraries like React/Redux, Angular, Node and gained knowledge with payment integration, real-time broadcasting, analytics, source management applications.
I can start your project immediately and promise to deliver good result on time.
As I have rich experience in Elm, HTML, React.js and Google Cloud Platform, I would be a perfect match for this project.
Thanks.
