October 2025: Implemented Threat IP drop filter for event ingestion in plausible/analytics, adding a new 'threat_ip' drop reason and header-driven logic based on x-plausible-ip-type. This feature reduces ingestion of malicious or unwanted traffic, improving data quality and security at the source.

September 2025 monthly summary for plausible/analytics: Implemented inter-node port range enforcement for non-self-hosted environments by adding kernel settings for network distribution ports and conditionally including them in VM arguments. This ensures non-self-hosted instances use a defined port range for inter-node communication, improving reliability, security, and deployment consistency. Change is traceable in a single commit and reduces port conflicts in production-like deployments.

July 2025 (plausible/analytics) — Focused on boosting monitoring data quality and CI efficiency. Key outcomes: refined OpenTelemetry sampling to ignore malformed/redundant routes; added a partitioned-testing matrix for Elixir CI; these changes reduce noise, accelerate feedback loops, and improve confidence in performance metrics.

June 2025 performance and reliability summary: delivered a targeted improvement to API health monitoring in the plausible/analytics repository by adjusting E2E test scheduling to increase responsiveness for critical endpoints.

Monthly summary for 2025-05 focusing on the plausible/docs repository. Delivered a branding refresh for the documentation site by updating the favicon, improving visual consistency and browser tab recognition with no changes to functionality. All work tracked in repository plausible/docs with a single committed change linked to issue 609.

April 2025 monthly summary for plausible/analytics focusing on security hardening and bug fixes in CRM admin views. Delivered a targeted XSS mitigation to safeguard user data and improve trust in analytics tooling.

February 2025: Stabilized the plausible/analytics ingestion path by performing a regression rollback on ScrollDepthVisibleAt initialization. Reverted the change that directly initialized Plausible.Ingestion.ScrollDepthVisibleAt and register_scroll_depth_visible, and removed scroll_depth_visible_at from the site cache, module, and tests. Implemented via commit b4ec09c6cb6bfe62ab7b413e1da80e2500b3436d.

January 2025: Analytics feature upgrade implemented by upgrading the ClickHouse server image used in plausible/analytics. This change was propagated to CI and local development via the Makefile to ensure environment parity, stability, and access to newer features/bug fixes. No separate bugs fixed this month; the upgrade reduces drift and simplifies future maintenance.

December 2024 monthly summary for plausible/analytics: A targeted CI/CD optimization was implemented by removing the automatic public Docker image publishing workflow, improving security posture and reducing unnecessary builds. The GitHub Actions workflow responsible for building and pushing public Docker images to DockerHub (.github/workflows/build-public-images.yml) was deleted in commit 0db71767269194fde742fe5a9b6d5864909b8cfd (#4917). This action mitigates exposure of public images, eliminates redundant image builds, and reduces CI compute usage. Major bugs fixed: none reported for this repository this month. Overall impact: streamlined release pipelines, lower operational risk, and clearer governance over artifact publishing. Technologies/skills demonstrated: GitHub Actions workflow management, Docker image publishing controls, security-conscious pipeline optimization, and change-management discipline.

November 2024 monthly summary for plausible/docs: Implemented a post-deployment CDN cache purge to ensure documentation reflects the latest changes, reducing stale content and improving user experience. The change was integrated into the Docusaurus CI/CD workflow and tied to BunnyCDN cache purging, enhancing deployment reliability and user trust.
