I may have no star ratings yet, because am new. However, am an expert when it comes to PHP, WordPress, MySQL, and API integration.
I keep up with the latest trends in the software development world. So I work with the latest editions of both WordPress Web and Desktop. I have integrated a couple of API to WordPress projects from Google APIs (Maps, AdWords), PayPal, Facebook, Tweeter, among others. Looking at Travelpayout, it is a very straight forward API. This means integrating it to WordPress will not be the challenge. I believe the work is in the design to make you website marry with the API. I am also good with database design, so your data will be well stored.
A good product is always defined by the extras it offers. With this in mind, after you brief me on how you would like your product to look and feel. I will do the following:
1. Prepare a proposal withing 24 - 48 hours;
2. After approval of the proposal I will work on a demo version so that you may test and experience the product.
3. Thereafter, with all your feedback in mind I will go a head and complete the product.
I can also offer support work. From experience, clients at some point may need extra work done for them. If it comes to this we may arrange for support.
