Worked on stabilizing FieldTimeSeries handling in the CliMA/Oceananigans.jl repository, focusing on improving the reliability of time-series analytics for simulations. Addressed a critical indexing bug by moving operations to the CPU, which enhanced efficiency and prevented errors during data access. Refined the logic for time-based comparisons by introducing an absolute error tolerance based on the simulation timestep, improving numerical robustness. Enhanced code clarity through updated comments and variable names, and ensured time arrays were consistently converted to ranges for safer downstream usage. Utilized Julia and applied skills in data handling, numerical analysis, and performance optimization to deliver these improvements.
