February 2026: Focused on stabilizing and modernizing the CI/CD and backend testing infrastructure for tloncorp/tlon-apps. Delivered an Ubuntu-based pipeline with improved performance and reliability, aligning test environments with production and reducing maintenance overhead.

October 2025 monthly summary for tloncorp/tlon-apps. Focused on stabilizing test reliability in SELinux-enabled environments and improving CI feedback for end-to-end tests. Key features delivered: - SELinux compatibility for end-to-end tests with Podman to allow reliable parallel test execution in SELinux-enabled environments. Major bugs fixed: - Resolved permission errors during E2E tests by configuring SELinux relabeling on volume mounts and disabling SELinux labels for Podman containers, enabling the parallel test runner to operate without SELinux-induced failures. Overall impact and accomplishments: - Improved test reliability and parallelism, reducing flaky test runs and enabling faster feedback for feature development. - Strengthened security-conscious CI / testing workflow by ensuring compatibility with SELinux without compromising test throughput. Technologies/skills demonstrated: - Linux security (SELinux) tuning, Podman-based testing, and end-to-end test reliability. - Change traceability and impact assessment via commit linkage (see commits below). Notes: Single commit associated with the fix: 59325a7abea034a948231d4f7cadaa941de46139 - "resolve selinux issues".
