Drupal is extremely flexible and the ecosystem of contributed modules is really large. This can, however, be overwhelming. Without a clear approach to delivering the particular project, it can quickly lead to:
a. the project turning to a mix of multiple approaches and modules which do not work well together, are unclear to the end user and require a massive amount of work to maintain and develop further;
b. choosing solutions that do not allow you to extend further without major refactoring which is expensive.
We can help, by architecting solutions, advising on best approaches, performing investigations and creating proof of concepts, followed by implementation or oversight of the implementation of chosen solutions. Down to the last line of code.
