March 2026 monthly summary focused on reliability improvements and enhanced data semantics for the tidy3d DRC workflow. Implemented a crash fix for directed edge-pairs and introduced polygon/edge-pair markers to distinguish same-layer from cross-layer violations. Updated parsing logic to support these semantics, boosting robustness and functionality of the DRC process.

July 2025 (2025-07) — Delivered a cross-tool design verification enhancement by adding KLayout DRC integration quickstart for Tidy3D notebooks (flexcompute/tidy3d-notebooks). The quickstart includes a Jupyter notebook demonstrating DRC on GDSII files or Tidy3D objects, loading results, and interpreting violations to streamline the verification process within the Tidy3D workflow. This feature is backed by the commit: Add KLayout DRC Plugin quickstart (c23d6e818355d1d09a03bac70f0b6bae59f7493d).

June 2025: Delivered a new KLayout plugin enabling Design Rule Checks (DRC) for Tidy3D, supporting DRC execution on GDS files and Tidy3D objects, loading results, parsing violation data, and providing utilities and tests. This feature strengthens layout validation, reduces design iteration time, and improves release quality by catching violations earlier. No major bugs reported this period; effort focused on feature delivery, test coverage, and documentation for downstream workflows. Demonstrates proficiency in plugin development, data parsing, and test-driven development to enhance design reliability and workflow efficiency.

May 2025 - Focus: Autograd traceability improvements in tidy3d. Delivered Autograd: Traceable Keyword Arguments for Interpolate and AddAt, enabling traceable kwargs in interpolate_spline and add_at primitives. Added tests to verify functionality and robustness in traced computations. Strengthened adjoint/autograd integration, improving reproducibility and stability for training workflows. Prepared groundwork for broader keyword-argument traceability across interpolation routines.

April 2025 Monthly Summary — Delivered robust testing enhancements, cross-format data interoperability with Zemax, and a practical grating-coupler optimization workflow, driving reliability, interoperability, and faster design iteration.

February 2025 monthly summary for developer work focusing on delivering visualization capabilities for permittivity tensor components in anisotropic media, including an API extension to plotting routines, improving material-property analysis and research workflow.
