We are a startup of human resources and we want to create a web application to basically hire people. It is a website that interacts with a database making queries and storing/modifying data. We need a proposal of the languages/platform we should use to build this. It has to be fast, efficient, scalable in time. We have very detailed mockups showing what we specifically we want, so the business idea is made. You only have to code what we want. About the visual design we would like to use bootstrap, at the beginning we don't want something very sophisticated, basic design is enough.
