I would like to hire a Coder

I need to be developed a web application with back-end Java to teach the operation of the Turing machine. The user opens the application and it is possible to insert the sequence to be analyzed by the machine, set the alphabet accepted by the machine, graphically show the step by step of the machine analysis of movement (being something totally simple and intelligible) and finally show the sequence was accepted by the machine. Requirements: - Database: Postgres (used to store every transaction, movement, step by step and the alphabet set by th user to the machine accepting). - Back-end: Java (used to coding the logical algorithm and communicate to the database) - Front-end: Angular.js (or other framework), Javascript, HTML, CSS, Bootstrap, etc. * Recalling that this project is aimed at students who have never had any knowledge about Turing machine, so I wanted it to be something well chewed, step by step, and clearly legible. ** Some examples to be help: - [login to view URL] (but it is very difficult to someone without knowledge use)
