Jun 1, 2025June 2025 monthly summary for hexlet-basics/hexlet-basics. Focused on stability, release readiness, and security improvements rather than delivering new user-facing features. This month’s work prioritized reliability of tests, deployment readiness, dependency security, and analytics accuracy. Key outcomes include: (1) test reliability improved by fixing a failing test caused by an incorrect survey scenario name; (2) release readiness enhanced via Kubernetes deployment chart version bumps; (3) security and stability reinforced through dependency upgrades in Gemfile.lock; and (4) analytics correctness improved by fixing Ahoy UTM tracking for visits. These changes reduce release risk, improve data quality for analytics, and demonstrate strong proficiency in testing, deployment workflows, dependency management, and instrumentation.

Jan 1, 2025Month: 2025-01 — Hexlet Basics development summary focused on security hardening, release readiness, and infrastructure alignment. Key work spanned server-side privacy header hardening, fixes to header delivery at Nginx level, and release/deploy process updates with version bumps. Key features delivered: - Permissions-Policy header hardened and enforced server-side across all responses; ensured proper handling for GET requests. (Commits: 65b2eb1a..., 9542394d..., f4fe3183...) - Release/readiness updates: updated application charts and Kubernetes deployment versions as part of the release process. (Commits: bce39983c2..., a36b984568..., cfacec4b59..., 2e7c92f97b..., 652edba8f3...) Major bugs fixed: - Fixed Nginx Permissions-Policy header syntax by adding the missing semicolon. (Commit: 7d3f6a4448...) - Additional fixes to permissions policy across commits to ensure consistent behavior (refinements in 9542394d... and f4fe3183...). Overall impact and accomplishments: - Strengthened privacy and security posture by enforcing Permissions-Policy headers across the app, reducing exposure risk and aiding compliance. - Improved release reliability and traceability through explicit version bumps and deployment config updates (Helm/Kubernetes), enabling smoother rollouts. - Demonstrated end-to-end delivery: server-side header hardening, nginx config correction, and Kubernetes-based release workflow. Technologies/skills demonstrated: - HTTP security headers (Permissions-Policy), Nginx configuration, Kubernetes deployments, Helm charts, and Git-based release practices.
