I use React and React Native to create a fully-fledged, universal architecture that maximizes the sharability of code between different platforms of one product, shortening time to market and minimizing the overall cost of development and maintenance. Software development is in the process of making a radical shift at the moment and Callstack is the company at the forefront of that. The more platforms a code can run on (e.g. web, iOS, MacOS, Windows, Android, SmatTV), the more useless and inefficient native languages for these platforms become - having one product available on 3 platforms which is a standard now (web, iOS and Android) means 3 separate teams working on 3, in fact different, apps. What if there was a technology that limits that to 50%? There is, it's called React Native and Callstack is at the forefront of the drastic change from platform-specific teams and products to shared codebases with the same quality and performance. We work on existing React Native codebases or design new from scratch, progressing with new features from even 30% to 70% faster compared to the same done in the native language, making sure the performance of the app is meeting rigorous criteria. Contact me if you want to build your software efficiently and maximize the code sharing across platforms.
