PROFILE

Kelvin Burke

Developed two core features for the starsimhub/starsim repository, focusing on enhancing simulation performance and demographic modeling accuracy. Improved the starsim.time module by optimizing date and duration operations, strengthening error handling, and introducing numeric validation for safer time vector initialization. Designed and integrated timeprob-based utilities to convert demographic rates into per-timestep probabilities, directly supporting births, deaths, and pregnancy calculations. Applied Python, NumPy, and Numba to achieve faster simulations and more reliable results. Refactored array utilities for maintainability and expanded unit testing coverage, ensuring robust, validated time series analysis and simulation workflows throughout the codebase without introducing new bugs.

July 2025 highlights for starsim: two major feature milestones with a focus on performance, robustness, and probabilistic modeling for per-timestep simulations. Implemented Time Core Performance and Robustness Improvements in the starsim.time module, resulting in faster date/time operations, safer time vector initialization, stronger error handling, and more efficient duration arithmetic. Introduced Timeprob-based Demographic Calculations and Probability Modeling to accurately convert rates to per-timestep probabilities and integrated it into births, deaths, and pregnancy calculations, with accompanying performance improvements. Strengthened stability with additional numeric validation, tests, and targeted refactors across time and arrays utilities. Demonstrated strong Python performance optimization, NumPy vectorization, and probabilistic modeling skills, delivering tangible business value through faster simulations, more reliable results, and improved demographic accuracy.
