Worked on backend development and dependency management across tscircuit and keycloak repositories, focusing on reliability and compatibility improvements. Delivered two features for tscircuit, including upgrading the EasyEDA library and adding POLYGON pad support to address a JLCPCB part issue, ensuring cross-repo alignment and smoother PCB design workflows. In the keycloak/terraform-provider-keycloak repository, fixed a critical bug by correctly setting the HTTP Host header in Go-based API requests, enabling proper routing for deployments behind reverse proxies or custom domains. Emphasized robust testing and API integration, adding end-to-end tests to prevent regressions and improve deployment reliability for downstream users.
