I have the necessary expertise and experience with several APIs, but before I answer your questions I need to know more details. APIs could be quite different than one another, experience in one does not necessarily help with the other. I need to know which APIs you are referring to, what is the data that needs to be exchanged? I can also provide a sample demo that uses one of these APIs when you PM me these details. Regards

Hello Thank you for posting this project Please check my reviews to know more about my professionalism and work quality I do have experience integrating RESTful and SOAP APIs, using XML and JSON as well. I did owrk on many many projects involving APIs of different types, payment gateways like Paypal, Stripe and others, projects with adhoc APIs, etc. One important thing and sorry for saying it this way: My desired bid value is about 4000 USD, im bidding the lowest value for you just to consider my bid. I do suggest if we progress and you consider selecting me for you to open a low amount project that you can award. I have had the experience with projects with a big amount that fail after award for any reason, but at freelancer.com the freelancer (me in this case) is charged the fee commision at award. Commision is 10%, so basically 300 o 400 USD that will be discounted on award. I prefer to go for a 500 USD project first for example and after completion, create a new one for 1000 more. Sorry for saying this, but i barely accept an award on a 3000 o 4000 USD project for the reason stated. Thank you and somehow sorry for this comment. Back to the important, i find your project challenging and very interesting, i can complete it for you on the best manner, i do have the expertise and know how to do it. Looking forward to your comments, best regards Diego PS: I do live in Buenos Aires, my timezone is GMT-3

Hello. Your quality parameters will be applied to the project. Would be great to discuss them in advance in order to agree on how will we include them. I have coordinated software deployment on premise and on cloud computing environments, specially targeting Linux distributions like Suse, Fedora, RHEL and Ubuntu, using Expect for automation. Also on Windows, but that is less common. I am not proficient on PHP, but I am on Java. With that language, the base framework could be Spring, through which we could integrate with Freemarker in order to generate the views, JaxB or Jackson to manipulate XML or Json, and MyBatis or Hibernate to handle persistence. If you rather other frameworks, no problem. Although I know the basics of HTML, CSS, and Javascript, I am not a full time web developer. Therefore, I can handle a basic web frontal or team up with a more experienced designer. My skills include the use of SCMs like Git, SVN, and Mercurial; SQL and NoSQL databases; automatic tests with JUnit or TestNG; JMeter; messaging with tools like ActiveMQ, Tibco and Kafka; Maven, and the deployment of continuous integration systems. Currently I am employed but I can manage my spare time to implement your project. Take a look of my résumé and if you have any questions, please let me know.
