HTTP/2 reliability · Two merged contributions
Fixed connection-pool scheduling so a long-lived HTTP/2 stream does not leave other requests stuck when another connection is allowed. A second fix preserves responses already accepted by the server when stream IDs arrive late. Both changes include regression tests.

Go · Merged contribution
Prevented panics when spreadsheet formulas access invalid ranges. Five conditional aggregation functions now return #VALUE! for those invalid accesses. The change includes regression coverage for the affected cases.

Public pull requests I authored in repositories owned by other people or organizations. Fork repositories are excluded; archived projects are included. Merged, open, and closed PRs are counted separately.
Both charts use merged PRs. The donut includes only programming languages, as classified by GitHub Linguist, and calculates percentages within that subset. It follows each repository's primary language, not language proficiency.
