Posted almost 8 years ago

$30-250 USD

Paid on delivery
I need to create a windows service in c# that will update the stock price in SQL server. - The stock table will host several stock symbols. - The stock price table will host the stock price. - The stock price table will host the historic values, many for the same stock - The stock values will be updated every minute from 9:30 A.M. to 4 P.M. eastern time - The stock price table will be appended, but never deleted or updated. - Every time you append the stock price, you will record the provider who provided the stock price in the stock price table. Very important: - The windows service needs to use 2 or 3 providers - you will need to rotate in case one fails, or rotate in case there are restrictions to updating the stock price every minute, 60 times in one hour, 480 times a day, for several stocks. - All code used must be royalty free, and you will need to provide the source for everything. You must answer these questions: - How many windows services have you built? - Have you integrated a third party API?

Hello, Thanks for giving me the opportunity to explain you my proposal. I would like to propose the following steps to build the Windows service: 1. Review with you the scope desired for the service and clarify technical details such as interfaces required (XML, .config, JSON, etc), start-up mode for the service, etc. 2. Confirm the APIs desired to be integrated .I've been checking some of the free APIs available (Quandl, CurrencyLayer, OpenExchange, Google, Yahoo) and we may not be able to meet the number of requests per day desired. We can do 1&2 over email or skype. 3. Based on the information agreed on 1&2 I will code the service and test it accordingly. 4. You will receive the service, test it and provide feedback on updates required aligned with the requirements agreed on 1&2. 5. Final modifications based on updates from 4. 6. You will test the modifications again and approve them. 7. Transfer the money (voila we're done!) My bid is lower from some other freelancers since it is going to be my first one at freelancer.com. In the past I have worked extensively building native applications for Windows environments such as virtual drivers, console applications, dlls, windows services, COM objects and ASP .NET sites. Answering your questions: - How many windows services have you built? : 10+ - Have you integrated a third party API? Yes, some of them: Google Geocoding API, MSFT WMI, Cisco NAC. Thanks and I hope we can work together. John Angel

Hi there, Greetings for the day! I'm an individual who worked for IT MNC Syntel Limited for 4 years as a full-stack .NET developer with expertise in C#, ASP.NET MVC, WCF, LINQ, MS SQL Server, Windows Services etc. I quit my job 2 months ago and decided to work as a freelance Software Developer to find projects which would utilize my expertise to the fullest and this project is perfect match, hence offering the bid. First of all I will attempt to answer questions you asked: Q.1 : How many windows services have you built? Ans: Between 50-100, may be more than that not sure about exact number. Q2. Have you integrated a third party API? Ans: Yes. Integrated many third party APIs in different WCF web service projects. Some worth mentioning are - Twitter API, Yahoo weather forecasting API, Used Amex(American Express) API for one of the company project I worked on for client American express. I know, I am not the one with extraordinary ratings and feedback as I am new to this marketplace and didn't get munch chances to work on projects in my expertise, hence you can see me bidding lowest of all, lowest possible I could manage, enabling me to get a chance to work on some of the best projects like this one and receive good ratings/feedback in return. I would like to invite you for discussion where i will explain my approach towards your project. I am also ready to do some tiny paid task to prove myself. Waiting in anticipation of your favorable reply. Regards, Shashikant M.
