Hello, I am a 8 years+ experienced C# developer. answer of your questions are given bellow: Q. Relevant C# desktop applications that you have developed A. Recently I have finished developing an inventory management system (WPF, ASP.NET, MSSQL) Q. Relevant VPN applications that you have developed A. Not any Q. The architecture of the desktop application that you have developed A. The Desktop part of the application was developed using MVVM pattern and the application architecture was Onion (n-Tyre). we used several patterns like singleton, factory pattern etc where applicable. We always respect SOLID principle in our design. I use WE because it was not a single man project we worked as a team and i designed the overall architecture and database. Q. The way that you want to approach such a project A. I will divide the application in to logical modules and develop one by one. I will share what I have understand from you specification. any design suggestions will be welcomed. to be frank it DID not developed any vpn client as I mentioned earlier but if you have proper specification I can definitely develop that for you. if you have any questions feel free to ask. Thanks Rased * milestone will be decided after specifiction

Dear Prospect, I have been through your job description thoroughly and would like to assist you in rebuilding your VPN application in C#. I would like to state that I have over 7+ years core programming experience in C# and .NET framework. I have done good amount of work on desktop applications in my professional career. 1) Worked on an online cabs management system which works through PDA's and Geographical positioning system. 2) Engineered a game or service through which we can find out the unrecognized users from the system by three ways (i) By taking screen shots after every 3 minutes (ii) By making a log of all the processes executed by malicious users. (iii) By making a log of files including list of process and screen shots as password protected. 3) Created a windows service in .Net which automatically installs SQL Server express edition on server, creates a database in it and if it already exists in database and it takes backup of the database after each day. I would like to review the existing app before finalizing the budget and time frame. I would like to have your preferences along with your detailed business and requirements specifications so that we have clear and complete scope of your application. To discuss in detail via Skype/phone call, let me know your availability and thoughts over it. I do look forward to get your positive response ahead for our next level of discussion. Kind Regards, Amit Chawla

Greetings! Sir, with due respect, I would like to submit a somewhat more than unusual inquiry. The thing is that I fully realize that you are willing to find a freelancer with the most cost-efficient offer. But after I analyzed all the requirements, I came to the conclusion that the quality of the final product might suffer a bit because of the amount of money you are planning to spend on it. So my question is: Would you be able to spend up to $4 500 on this project. If so, I will provide you with my assistance, a proper estimate with a detailed report on every single penny we want you to pay for it and all the Mandatory and Optional details. If not, I sincerely beg your pardon for having wasted some of your time. Kind regards, Anton.
