TLI is a web application system to manage a purchase-deliver workflow. It handles the whole workflow, starting with the client doing the purchase and ending with the package being delivered. The main goal is to keep continuous track of the package (where it is, in which city, truck, container, etc.) and show this information to the customer. For that reason we had to handle trip's bookings, services, drivers, carriers, shipping companies and more. The development was focused on the usability and maintainability of the system. It was developed with Ruby on Rails, jQuery, Formtastic, Cucumber and Rspec.


This is a portal for the Panama government which manages citizenship applications. But is more than a simple portal because it has dynamic form rendering mechanism. The system uses templates generated by FCDesigner and documents as data to render the application forms. Also, those forms are filled with some data gathered from REST services and documental databases. This was developed with Ruby on Rails, jQuery, Formtastic, PaperClip, Savon and CouchRestModel.


For FCPortal we needed to develop a Module to manage accounts of millions of people. The created accounts lets people access to a distributed system and, also, get access to external processes management and its setup. The system was based on REST services and was the accessibility core for government applications. This developed using Ruby on Rails, Devise, CanCan, jQuery, CouchDb and OmniAuth.


FCDesigner is a very complex platform to create application forms using templates or reusable parts of them. This let the user create a lot of applications forms reusing small parts with their own structure, texts and validations with the all the complexity you can imagine. It's an excellent example about how to use ruby meta programming. We used Ruby on Rails, jQuery, MetaSearch and specially lot of thinking :)

  • Each day the team makes a brief meeting (5 minutes) to communicate what are they doing and solve daily issues.
  • Near the end of the work block, the team refines the work that remains to be done, reprioritizing according to the new understanding of client's business.
  • At the end of the block, the team delivers a version of the product that meets the customer needs agreed with them for that block.
  • The new version is reviewed with the client, who will test that the system behaves according to your expectations.
  • Before starting the cycle again, the team makes a retrospective meeting to discuss what went well and what needs to be improved about the way of work.
