PROFILE
James Wright
Over a nine-month period, contributed to the dstl/Stone-Soup repository by building modular kernel APIs, enhancing tracking algorithms, and improving simulation reproducibility. Applied Python, NumPy, and YAML to refactor kernel hierarchies, introduce path-driven platform movement, and implement deterministic seeding for sensor simulations, supporting robust state estimation and reproducible results. Improved documentation and code quality through technical writing and linting, clarified mathematical notation, and expanded test coverage with unit and integration tests. Addressed 3D plotting accuracy and copyright compliance, ensuring regulatory readiness and reliable visualizations. The work emphasized maintainability, extensibility, and onboarding, aligning with best practices in scientific computing and software development.
