C++ Developer
2022 - 2022Freelance- Upgraded import/export scientific data from/to NetCDF files from version 3 of C++ API to version 4. The new version significantly changed several aspects of the API, like reporting errors through exception, reduction of a pointer using, and more.
- Improved memory management by reducing (nearly eliminating) usage of pointers.
- Designed and implemented a lightweight bridge to the version 4 of NetCDF, so there are minimal impacts on the original code.
- Incorporated exception handling into code that did not use exceptions.
