PROFILE

Tim Kornhammar

Worked on cloudflare/cloudflare-docs, delivering five features over five months focused on cache management, API development, and documentation. Built the Cache Response Rules feature, enabling users to modify cache-control directives and manage cache tags, and implemented asynchronous stale-while-revalidate serving to improve content delivery performance. Enhanced cache observability by adding audit logs and cache key inspection, and migrated changelog entries for better documentation governance. Updated documentation to clarify R2 tiered cache compatibility, aligning docs with product capabilities. Used JSON and Markdown for technical writing, applied Terraform for infrastructure examples, and demonstrated strong collaboration across documentation, API integration, and CDN management workflows.

March 2026 (2026-03): Cloudflare Docs delivered the Cache Response Rules feature enabling users to modify cache-control directives, manage cache tags, and strip headers from origin responses before caching. Documentation was added and resource links corrected for accuracy. Major fixes included dashboard and docs link corrections and parameterization of the APIRequest path. Impact includes improved caching control for users, faster onboarding, and higher documentation quality. Demonstrated technologies/skills: API design, docs engineering, changelog hygiene, Terraform example integration, and cross-functional collaboration for CDN migrations.

February 2026 — Cloudflare Docs: Focused on performance and reliability improvements by delivering asynchronous stale-while-revalidate (SWR) serving. Implemented SWR async handling to serve stale content immediately while revalidation runs in the background, reducing user wait times and improving perceived performance. This was complemented by updated changelog/docs clarifying SWR behavior and its impact on request handling during revalidation, enabling clearer tech debt reduction and smoother onboarding for contributors. The work demonstrates strong cross-team collaboration and a measurable uplift in content delivery responsiveness.

January 2026 — Cloudflare Docs: Changelog Migration and Cache Feature Documentation. Migrated six inline changelog entries from src/content/docs/cache/changelog.mdx to dedicated .mdx files and added three new entries covering cache features introduced between 2025-02 and 2025-08. Cleaned up legacy content (36 lines) and applied code-review suggestions to improve clarity, consistency, and maintainability. This work enhances discoverability of cache changes, simplifies future updates, and supports scalable documentation workflows. No functional bugs fixed this month; primary impact was documentation quality and contributor onboarding.

November 2024: Delivered a targeted documentation update in SamyPesse/cloudflare-docs to reflect Tiered Cache R2 compatibility. Removed outdated note that R2 is not supported, clarifying tiered-cache capabilities and reducing developer friction. This aligns docs with product capabilities and improves onboarding and support for R2-tiered caching.
