GIVING NEW LIFE TO LEGACY SOLUTIONS
As a team, we are specialized and enrolled in several enterprise-level, multi-tenant, multinational software solutions used by numerous clients. Some of the solutions are inherited, legacy applications, and bearing that in mind, our teams had to specialize in a demanding task of working with legacy code.
There are several definitions of legacy code, but all of them share the same commonality, it is a code inherited from someone else, not designed by the current maintainers. Another important aspect of it is, as Michael Feathers puts it in his famous book Working Effectively with Legacy Code: “To me, legacy code is simply code without tests”.
Working on an old, legacy code is always a challenge, there is usually no proper documentation, nor even proof of it working properly, except for users not complaining. Considering aforementioned and software’s tendency to change, every time new requirements come in, engineers are faced with a challenge – how and will they notice, when there are no tests in place, if their change breaks some of the existing, working functionalities.
Other difficulties reflect upon code clarity. Simply put, code is an intellectual output of an individual’s understanding of a problem he or she is trying to solve at the time. That understanding translated into the actual code is unique to the individual’s thinking and it is very rare to see two people solving the same problem in the same way. Keeping this in mind, it is not hard to understand why it is so heavy on developers.
Working successfully on legacy platforms for years and facing the fact that technologies change very often, but software systems do not follow this pace, we have made it our mission to learn, develop and help others work their way through with their legacy platforms and, specialized to convert, test, document, and deploy them to the latest technologies.
We have designed several protocols and tools for the coping with the legacy code, and we are more than happy to help you and your team with your legacy platform challenges
