This project is for a cross platform c# RESTful web service returning JSON data which will be used to maintain a MySQL employee database in a payroll system. We will provide the exact database schema but it will be comprised of 1 parent table (employees) and 4 child tables (addresses, phones, emails, deductions). Please also include in your bid a simple web interface in order to test functionality of the service. We plan on quickly expanding your software to provide access to a full featured payroll system and hopefully you will be available to do that. In your bid please tell us how long this first step will take along with a description of the methods and tools you plan to use.

12+ years experience in small, medium, enterprise scale application I have created a sample REST application for this project (mapping the CRUD operations)and is hosted as mentioned below: URL for API documentation: [login to view URL] The api URL: [login to view URL] I can show you manageable, modular scale-able code written for this project, which is available in my GIT repository. The application here connects with MySQL. The service layer is separate from DB layer providing the needed abstraction. Since I am using ORM (object relation mapping) technique, it makes it easier to incorporate changes, scale and maintaining code/db integrity, even change databases if ever required. Do mail/ping me if you have any questions.

It will take me 5 days to complete this (However I would try to get this done in 3 days). I am based in USA, we can communicate in any time suitable for you to discuss. Following are proposed technical implementation details: Application Type: REST API Server Side Technologies: C# Database: MySQL I am expert in ASP.Net, C#, VB.Net, MVC REST/Web API, AngularJS, javascript/jquery, css, html, MySQL Server, php so not to worry about anything.

I'm a professional API developer using full Microsoft stack technologies over 10 years. I can provide you a complete solution with 4 projects inside: database level data access level restful api integration tests Solution will be done using free VS Community 2015. 5 days should be enough to provide all the above, then we just try to apply in on your full database and fix the bugs if any. Please keep in mind, that I estimated only 4 standard CRUD methods. Search/List using proper filter was not included, as it's too expensive and will not fit the budget from my point of view.

I am a professional C# developer with multiple years of experience developing RESTful APIs that have provided performant data acccess and manageable business functionality for multiple clients. I am not exactly sure what you mean by a simple web interface for testing but a psuedo interface for what you are requesting would be the following: Address SaveAddress(Address employeeAddress); void DeleteAddress(int addressId); Email SaveEmail(Email employeeEmail); void DeleteEmail(int emailId); Deduction SaveDeduction(Deduction employeeDeduction); void DeleteDeduction(int deductionId); Phone SavePhone(Phone employeePhone); void DeletePhone(int phoneId); Employee SaveEmployee(Employee employee); void DeleteEmployee(int employeeId); I plan on using Visual Studio 2015 .NET 4.5.2, but I am willing to use an older version if your environment doesn't support it.

Hi I am a C# MVC developer and am fully familiar with using Restful WSDL or WebAPI technology. I propose using WEBAPI to provide JSON responses as it will allow connectivity to multiple databases. I have over 8 years of commercial experience .

Hello, I was recently employed in a team to build a WEB API like the one you require. You can check www dot mykredit dot com , this website is designed on microsevice architecture, MySQL server used to store data and we used Restful web services to communicate between front-end and back-end. I'm going to develop by using ASP.NET Webapi2 on 3-layer architecture which are service-layer, bussiness-layer and database-layer. If you allow me to, I want to user Nhibernate or EF6 as ORM to communicate with MySQL and back-end service. I already have developed such projects, I'm currently unemployed which means I have plenty of free time. The time needed to complete this task depends on how big the database schema. The service layer is going to have universal HTTP operations (cross-platform) GET, PUT, POST and DELETE. Get to select, PUT to update data, POST to insert and DELETE to delete data from database. For each of your database table, I'm going to make a service having those 4 operations and this won't take much time. But in the data layer, the more tables there are, the more complex operations would be implemented to interact between tables. I'm going to use linq-2-sql to write db queries. If you have any questions please contact me. For the first step, it will take 3 days including including unit test project. If you don't want me to develop with unit testing, I can provide the source code in 2 days.
