We are a company with many years of software development experience placed in Spain. We are looking for outsourcing pure code development, to let us to concentrate on integration, product development and commercialization. The APP in a simple contacts manager working over GMail Contacts. It is just an alternative to default Contacts Manager in Android with diferent layout, basically thinking on business people needs. We need native development with Android studio (Java and Kotlin languages). This APP will grow up with more functionalities. But only one new functionality by stage. We provide full layout style, icons and design. Designs are made with CorelDraw so we can povide all graphics in SVG or any other scalable format. We plan to work with Bitbucked repository and with Trello for organizing task. (But not fixed yet, we are having a look to GitLab for this new project) Project must be ready for internationalization with locallized properties files. We look for long time relationship while project gets bigger. We can connect using Spanish or English. This is the mobile part of the whole CRM alike project. This is the early MVP APP for testing markets. Rest project includes, web development and a windows service to syncronize local data store in MS Access accdb files with external web service. (Using MS Access files is not up to us. It is an external requiment)
