C++ developer with a heart for performance and efficiency 

ObjectBox helps app developers develop faster apps faster by ensuring data is where it is needed when it is needed. The core is our high-performance, lightweight, embedded database written in C / C++ with easy native-language APIs for Java, Kotlin, Swift, Dart (Flutter), Go, and C / C++. On top of the database, we’re building an out-of-the-box Data Sync (think of it as a git for data; already used in settings which require industry-grade robustness, though we still see it as Early Access; demonstrated great efficiency). We’re also extending the database into a vector database (for Edge AI) 🙌
