Building a RESTful API with high scalability

I'm looking to build a RESTful API that would be in charge of inserting datas based on the data sent by multiple mobile apps.

I've already developed an API that you can find here: https://github.com/Noeru14/fms. It uses Gin: https://github.com/gin-gonic/gin. If I opened too many parallel connections, it used to crash / not work properly.

A friend of mine has talked about using Node instead as it allows to have really short client-server interaction.

I'd like to know which factors I'd have to take into account to build a RESTful API that could handle up to hundreds of thousands requests per second. Do you also know if it's doable in Golang ?

Thanks a lot.
