English: We are loogking for support to develop our new api. We want to offer our calculations online by an API to our customers. Therefore the customers information should be stored in a MySQL database and the connections to the calculations should be verified and stored for the billing process. As well we need a demo and test client for all calculations. For more information please check the attached file. It is a first idea, how the api should work and gives you an idea of the project size. We are open for new ideas! The project should be finished and tested until end of february 2015. Please contact us when you are interessted in the project. With kind regards André Schallöhr ############################################## Deutsch: Wir suchen Unterstützung bei der Umsetzung einer API. Ziel ist eine API, um unseren Kunden lizensierten Zugriff auf unsere Berechnungen zu ermöglichen. Der request kann nur von lizensierten Kundenservern erfolgen und auf eine lizenzabhängige Anzahl von Berechnungen zugreifen. Neben der API an sich soll auch ein Lizensierungsmodell und Rechnungssystem erstellt werden sowie ein vollständiger Test Client der über eine Zugriffsbeschränkung auch als Democlient verwendet werden kann. Im Anhang haben wir die unsere Vorstellungen der API so detailliert wie möglich skizziert (Englisch) um den Umfang des Projektes darzustellen. Über Ideen und Verbesserungsvorschläge zur Umsetzung der API würden wir uns freuen. Das Projekt sollte bis Ende Februar fertiggestellt werden. Mit freundlichen Grüßen André Schallöhr

Dear André, I have familiarized with your project's description, read the attached PDF and visited the enclosed links. I think I understand the flow of the applications based on the API you are trying to build. From my understanding you would like to give your clients/customers an ability of using your calculation algorithms based on free/paid license plans, so that their own customers can use the calculations. I am only unsure whether you would like to allow your customers to pay for the licences online. As far as I understand the customers can simply request licences via an online form and then receive invoices based on their monthly usage. Is it correct? Obviously, I am also aware of the security best practices included in the german PDF (Ich spreche ein bisschen Deutsch) and OAuth authentication method. I am confident we can build such a tool for you. If you would like to read more about our our team please check the following brochure: [login to view URL] (password: mstones). Please let me know whether you would like to discuss the project in more details. Thank you! Best regards, Jacek Francuz

Hi there, I've gone through the details, we've built API's in the past so it shouldn't be an issue. I did want to ask, how are you handling payments? are you doing it separately or did you need an interface to handle that as part of the API? Finally, just wanted to make sure you're aware before we start any project over £1000 we ask for a 50% deposit paid upfront. Alternatively we can take a 25% deposit and do the remaining 75% on 3 milestones. Warm regards James

Hi,I read everything you posted and i see you want to build a secure api that allows your customers make requests to perform certain licensed calculations which would be logged and automated with the client having a max number of calculation he can perform per license,and a whole lot more as you mentioned in the attached pdf. I can get this done for you, am a well seasoned developer with over 8yrs experience,i've worked on accounting applications with complex algorithms, you can be assured a job well done. Also, i would need to see a sample calculation so i can have a better idea the nature. Would be great to hear from you. Cheers.

I have a computer engineering degree from CMU and 20 years development experience. I've used MySQL for 10 years as a programmer ad admin. And I've probably developed 100s of APIs. I used to work with banks and they would interface with a vendor to handle their financial transactions. This is a pretty simple API and the work that gets done by it is pretty simple too. I've developed large projets in the past -- with over $1M budgets and up to 20 people. So I can handle things of scope. If you think I can help you, please write. You don't have to pay me until it's done.
