Parsers and algorithms for computational chemistry logfiles
Role in this project:
Back-end Developer
Back-end DeveloperContributions:50 commits, 15 PRs, 36 comments in 2 months
Contributions summary:Sanjeed primarily contributed to the development of a CJSON writer for computational chemistry log files. Their work focused on creating a structured JSON representation of the parsed data, including properties, atoms, optimization data, vibrations, and bonds. They implemented a `NumpyAwareJSONEncoder` to handle NumPy arrays and ensure valid JSON formatting and added functionalities such as indentation and handling of missing values within the JSON. Furthermore, the user refactored code to improve organization and readability.

Avogadro libraries provide 3D rendering, visualization, analysis and data processing useful in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas.
Role in this project:Back-end Developer
Back-end DeveloperContributions:21 commits, 5 PRs, 7 comments in 22 days
Contributions summary:Sanjeed primarily focused on enhancing the cjsonformat library within the Avogadro project. Their contributions included updating descriptions, fixing function name typos, and adding new functions to the `cjsonformat.cpp` file. Further work involved breaking down the read function into smaller components and filling out functions to parse the cjson structure, including adding getters/setters for atomic masses and supporting for molecular orbitals and vibrations, along with other molecular data.
