PROFILE

Lucien Coffe

Worked on the lightpanda-io/browser repository to enhance build reliability and network security features. Addressed a critical issue in the Makefile by updating the Zig compiler download URL, ensuring automated toolchain retrieval and stable CI builds. Developed outbound network filtering to block HTTP requests to private and user-defined CIDR ranges before the TCP handshake, using Zig and Makefile for build and implementation. Introduced allow-list support and standardized CLI flag naming for improved usability. Emphasized security best practices by enforcing fail-closed behavior and expanded test coverage, resulting in more predictable releases and strengthened network policy enforcement within the project.
