REPLware is a software consulting company dedicated to bring our customers customized software with high quality. Software development is difficult. According the report from the Standish Group, only 16.2% of software projects are completed on time and on budget. The top three of the project challenged factors are: Lack of user input, incomplete requirements and changing requirements. Understanding the challenges mentioned above, we deliberately choose to work as a small team. Also, we choose Clojure/ClojureScript/Datomic as our primary technical stacks. The Clojure programming language helps us to conquer the challenge of changing requirements. Clients who work with us turn their ideas into software, which then increase their efficiency by 20%. They accomplish this without hiring an in-house software development team or waiting for an indefinitely long time.
