C++ Engineer
2022 - 2023
Rota Geek Limited
- Designed and optimized advanced genetic algorithm for optimizing scheduling and rostering rules and constraints from laws and trade union rules.
- Solved a lot of bugs inherited from the last team that made the application sporadically crash. That significantly improved the service availability and reduced the huge deployment costs.
- Made the solution cross-platform to work on all three major desktop platforms (Windows, Mac, Linux). That helped each team member develop on their preferred platform but also helped in finding bugs and solving bugs.
- Managed the cloud infrastructure that was quite complex, having parts of the solution deployed on Azure, AWS, CloudAMQP, etc.
- Implemented telemetry and internal tooling to help visualize the process in real-time and post-analysis. Previously the algorithm ran as a black box, producing no such information.
