Please describe your billing model. Do you accept part payment at certain stages of the project. Will will be aiming to hold back a significant percentage until full delivery of the project.

We ask clients to pay for 30 work days of development in advance, and invoice at least monthly with payment due by wire within two weeks. For clients unable to pay 30 days in advance, we can accept 15 days in advance and weekly invoicing with payment due within seven days. Some clients with exceptionally strong credit ratings or funding are exempt from payment in advance (e.g. we did not ask Twitter or Morgan Stanley to pay in advance).

If we follow our normal agile development methodology based on time-and-materials billing, we deliver fully integrated and operational iterations of a...

Intellectual property

Please describe your policy on intellectual property (IP) in relation to your customers' creative ideas. How do you protect their IP? Are you happy to sign a non-disclosure agreement? We will need the contract to be "work for hire" where we retain full intellectual property and copyright in all work done on the project.

We do work under NDA. We protect IP through NDAs with all employees and would aggressively support prosecution of any employees violating client IP protected under an NDA with East Agile. We understand IP, including many of the subtle complexities.

We have internally developed code and libraries that we can grant clients a non-exclusive, transferrable right to use. Or we can re-invent those wheels using developers with no knowledge of our...

Testing & QA

How do you test your applications? What QA processes do you have? How do you handle issues discovered during user acceptance testing? Are these fixed promptly at no additional cost?

Testing drives our development process. We follow rigorous Test Driven Development (TDD) methodologies. Before we write code for any feature, developers first implement tests, then they write code to make their tests pass. Both tests and code are constantly refactored during development. Typically for each 1000 lines of code there will be a 1000 lines of associated tests. A wide range of tests are created during development, including tests of user interface functionality using Selenium. Tests are run continuously throughout the day as part of the development process. Writing the tests...

Do you have any live URLs of work you are proud of? Have you completed projects that have similar features and functionality to We are especially interested in any "Web 2.0" applications with multi-user accounts and payment systems.

Smartphone Applications

Do you have any experience of developing smartphone apps?

Adam Blum
CEO, Rhomobile
We have a mobile platform development team. We develop for iPhone, Android, Blackberry, Symbian, and Palm WebOS. Our iPhone team has particular strength in geo-location and mapping applications. We have also been selected by Palm, Inc. as a recommended phone application developer.

We can create iPhone apps directly in native Objective C. See Abbott Labs' Similac Mom application on the Apple App Store.

Our current preference is to develop apps using the HTML5 oriented Phonegap system. This allows us to continue to use our full set of strong Behaviour Driven Development (BDD) and Test Driven Development (TDD) practices to create while developing for iPhone and other mobile...

What security measures would you take to protect an application of this nature? Eg from external sources - unauthorised access, hacks, DOS attacks etc. In addition, do you have experience of ensuring that registered users do not have access to other user accounts/data from within the same application? Are you aware of these risks? How would you prevent them?

We usually use RESFUL authentication framework when authentication system is required. There are several such frameworks in Rails, open-source and carefully tested. In some particular situation, OAuth can also be used to avoid or mitigate risk. For DOS attack, currently we mainly depend on the host service provider.

Please describe how you would deploy an application of this nature including reference to any development, staging and production servers. What systems would you put in place to roll out upgrades after the application goes live? Also, how would you create a 'down for maintenance' page if we needed to do some emergency work to alter the application without loss of user data?

-For deployment, we prefer the use of Capistrano since it supports remote deployment, rolling back and release version control. In addition, Capistrano also supports the configuration of “down for maintenance” page.
- Normally, we use git style management features to handle different environments. Usually, we have 2 branches: production with stable code and development with newly-implemented code. Two...

Technology platforms

If you were asked to build an application like, what technology platform would you use? Eg PHP, Ruby on Rails, .Net, MySQL, SQL Server, Apache, IIS etc. We know this depends on a lot of things but please just give us your first impressions.
What payment system choices would you initially recommend?
Please explain your choices above. We would like to get an idea of your preferred technologies and your expertise with them.

If we were implementing a system such as the one described we would use Ruby on Rails on Engine Yard managed Amazon EC2 infrastructure (Linux, MySQL). Rails is a natural, proven, scalable choice for this sort of application that would enable rapid test driven development with strong security, strong standards, and manageable...
