Jan 1, 2026January 2026: Delivered improvements in netlist generation, naming consistency, and port modeling, delivering measurable business value through more reliable circuit layouts and faster iteration. The team implemented Netlist API enhancements (get_netlist/get_netlist_recursive), namer protocol upgrades and stateless namers, PortMatcher, and an enriched Ports data model. We hardened the development process with CI tooling, pre-commit hooks, and test stability fixes, resulting in fewer regressions and smoother releases. Technologies demonstrated include Python, type hints and mypy, refactoring, test engineering, and CI/CD practices.
