  Dec 2009 - Dec 2015

  Played a key role in the development of a competing platform to Google Maps, focusing on the performance and scalability of the map rendering server. This involved integrating real-time traffic data, optimizing rendering service for speed, and streamlining the deployment process. The server was developed in C++ with a strong emphasis on maintainability, achieved through a minimalist coding style and comprehensive test coverage. Furthermore, I led the effort to break down the existing monolithic architecture into a set of well-defined libraries with semantic versioning and rigorous integration testing, improving code reusability and accelerating development cycles.
