See attached Word Document for more detailed RFP. Overview [login to view URL] is in need of an API service to provide to customers. This will house all of our U.S. and Canadian Postal Code data with the data being retrievable in several different ways. We would like to offer two levels of the API: Free and Paid. Both versions will have a daily limit on the # of calls that can be made (that can be overridden). This project includes developing the main API only. Tie-ins to the website, billing, and some account maintenance functions will be developed in house. These items need to be detailed out, but we will be working closely together. Technical Requirements 1. Must be hosted in a cloud environment that can scale to very large demands. a. Microsoft Azure is one option b. Other options? Suggestions? 2. Preferred to be developed in .Net a. C# or VB 3. API Output language will be JSON. If XML can be provided quickly and easily, it should be added. What other formats are common or APIs? 4. Must work with SQL Server 2008 and 2012. 5. Data will be updated monthly and we have U.S. and Canadian data. The schemas for the two main postal code databases are very different while some endpoints must work across both tables. 6. If possible and feasible, developing methods of caching certain data is preferable to speed up the service and reduce processing overhead. 7. Must be able to introduce API Rate Throttling and/or rate limiting. 8. Must be aware of XSS, SQL Injection, Large Payloads, and other threat vectors with ability to protect from these. 9. Must have plan for API versioning. Example: //[login to view URL] Budget Please provide several cost proposals to accomplish the scope outlined below. The budget must encompass all design, production, and software acquisitions necessary for development and maintenance of the web site. List pricing for: 1. Phase I: Discovery, Requirements Planning & Site Definition 2. Phase II: Site Development, Testing and Deployment Other Requirements 1. Must integrate with [login to view URL] for permissions and API keys 2. API Keys will be limited to # of calls, but we should have the ability to manually tweak these as needed. 3. Full daily usage stats should be able to be retrieved along with # calls since last billing cycle. 4. Ability to turn on detailed stats in case an API key is being abused (IP, what is looked up, timestamps, etc). Qualifications We need someone who has had experience developing a commercial API before. We also want to move this info a cloud hosting environment, so knowledge and understanding of this is required. We will need advising and help in not only selecting a provider, but also in the setup and maintenance.

There is no word file, please attach the word file so that I can provide you the bidding details in the format that you have asked for anyway I went through your project description and understand that you are looking for people who have previous experience in creating API services for websites. In the absence of similar projects I would really like you to allow me to prove my skills to you, to do this I will be more than happy to create a demo website for you free of cost, this way you don't have to pay me anything and I get to prove my skills to you. Regarding the project itself you don't have to pay me anything in advance you only pay me the entire bid amount once the project is complete. As per freelancer policy I cannot initiate exchange of messages with you so if you want me to work on the demo then please leave me a message and I'll get started right away. All you need to do is provide me with a list of things you want to see in the demo. PS:- please ignore the milestone request as per freelancer policy we are required to provide a minimum milestone request of 20%. Please before you reject my offer at least try to clear all your doubts with me.

We're an professional Australian-based development team who specialises in .NET Web applications. We're well versed in delivering API using the ASP.NET platform. REQUIREMENTS: We would write this project in C#.NET, using .NET's WebAPI library. This will expose the API interface through both XML and JSON (client selects mode by query parameter). Database integration is easiest with SQL 2008/2012 - which fits perfectly with your requirement. In terms of hosting, we're well versed in both Microsoft Azure and Amazon Web Services. We generally favour AWS as it provides more fine grained control of the hosting experience. This is a field that we would lead you through, and let you select the provider you prefer. For caching we recommend using .NET's built in MemoryCache. This cache performs excellently, and is constrained only by the amount of RAM available. With data being updated monthly, we may well be able to cache the entire database in RAM on each server, providing super-fast access times. Both AWS and Azure lend well to scalability. The code we produce can be scaled from a single server up to hundreds. COSTING: Phase I: Discovery, Requirements Planning & Site Definition Based on the described scope we can address this for US$2000 Phase II: Site Development, Testing and Deployment Without scope changes, we can complete this phase for US$2700 I'd love to talk more to discuss these requirements. - Ben Thompson

I am American, live in NYC, have a BS and a day job; I need extra projects this month. I am free to talk on the phone as well anytime. Please let us chat before you approve the bid just to make sure we're all on the same page. Notes on cloud computing: I have migrated (and built) many services and systems that use Amazon AWS. I can learn other systems, as I'm sure they all have the same principals, but AWS is something I know using EC2 and S3 and the database engine as well. I would be glad to elaborate on any level you'd like, Thanks, Joe
