Open-source contributor from Taiwan, focused on the Ant Design ecosystem, accessible React components, reproducible bug fixes, and Traditional Chinese localization. I also build practical AI workflows through AgentJE.

• AgentJE: AI tool integration, workflow automation, system delivery, and practical adoption for Taiwan SMEs.
• CommScope Communications Systems Taiwan: Intern, June 2025 - June 2026, reporting to QA Engineering.
• National Taiwan Normal University: Department of Technology Application and Human Resource Development (Technology).

These figures exclude repositories I own and count a PR only after GitHub reports it as merged. Open and approved PRs are never included in the merged total. The review count includes published reviews on other authors' PRs, not a claim of current-head approval. See the complete contribution and review evidence and the dated public snapshot.

• Accessibility and interaction: accessible names, keyboard behavior, focus handling, semantic DOM, and form-safe controls.
• React component correctness: controlled state, lifecycle boundaries, numeric-zero rendering, drag-and-drop, overlays, and cross-package behavior.
• Traditional Chinese localization: Taiwan terminology, interpolation safety, runtime locale wiring, and assistive-technology text.
• Evidence-based review: exact-head verification, base-versus-head regressions, independent boundary probes, CI interpretation, and duplicate-work checks.

• Ant Design: correct Traditional Chinese picker terminology while keeping public locale contracts synchronized with regression coverage.
• Ant Design: prevent Notification close controls from submitting forms, preserving native button semantics in embedded forms.
• Ant Design: preserve List items whose row key is numeric zero with a focused React key regression.
• React Component Tooltip: preserve existing aria-describedby relationships instead of replacing consumer accessibility metadata.
• React Component Slider: support aria-describedby on single and range handles.
• React Component Tree: preserve consumer drag payloads instead of overwriting public text/plain data.
• LocalSend: improve reviewed Traditional Chinese wording for Taiwan users.
• Neovim: complete and repair the Traditional Chinese message catalog while preserving catalog structure.

• validator.js calendar-date review: verified every four-digit year across 3,960,000 date cases. The patch rejects 67,575 previously accepted impossible dates with zero remaining mismatches in this corpus; all 321 tests pass. InputNumber issue triage: traced stale first-keystroke formatter data to an already-merged fix, verified 170 tests and reproduced the old failure by removing the relevant line.

• Marked #4086: preserve literal tabs inside list code spans and fences. Addressed the maintainer's format request with 16 Markdown/HTML fixture pairs; all fail on base and pass with the fix. Full validation passes 1,833 spec-harness tests, 191 unit tests, build and lint. The signed/Verified PR remains open; upstream tests and Vercel preview require maintainer authorization.

• Marked list performance review: verified unchanged full token trees and HTML across 110,800 comparisons. A 500-level list used a median 124.3 MiB peak RSS versus 198.5 MiB on base in five local runs each. Day.js invalid-date review: verified the NaN correction and documented a separate, unrelated unit-alias change for maintainer decision.

• Commander #2608: the maintainer closed this test-isolation proposal without merging on September 6 (Taipei), choosing to treat it as a support example for #2549. The historical six-configuration / 1,420-test validation remains documented; the change is not adopted or counted as merged.

• Latest reviews: Commander subtree validation identifies an unhandled addCommand construction order that still swallows forwarded options; ESLint import default exports verifies repeated-lint correctness with 13 independent checks and 3,015 passing tests. Both reviews document exact commits and validation limits.

• Newly merged: Oh My Zsh #13932, preserving the Poetry environment while navigating project subdirectories. The maintainer merged it on September 6 (Taipei).

• Cross-project reviews: Commander Electron parsing, Day.js ISO weeks, and validator.js JWT structure, each published against the tested commit. The Day.js review independently compares 534,744 local/UTC cases across four timezones, with zero mismatches after reproducing 357 baseline failures.

• Picker #1013: fix localized month input being parsed with the wrong global language. Six regressions fail on base; the fix passes the full 481-test suite and 29 snapshots, preserving strict validation and fallback for unloaded locales. Upstream test, Surge Preview and React Doctor workflows now pass. The signed PR is open; Vercel preview still requires deployment authorization.

• Ant Design #59223: preserve ConfigProvider properties when local nested styles override one property. Resolved all four review threads and the coverage failure. All 45 applicable upstream checks pass (three additional checks are skipped), including the three visual shards; Codecov reports all modified lines covered and 100% project coverage. The PR remains open.

• Ant Design Tools #298: preserve binary image imports, choose the correct module format, and prevent stale image caching. Seven base-failing regressions pass after the fix; Ant Design Image consumer validation passes 118 tests and 56 snapshots. The signed PR is open and upstream CI requires maintainer approval.

• Tabs #59221: approved the exact popup-style fix after a base reproduction and independent probes. The review discloses one identical base/head snapshot mismatch in the otherwise passing related-suite run, plus existing nested-style merge behavior.

• Ant Design Tools #297: fix stale Jest transform caching. A two-process regression proves that an edited module is recompiled; the patch passes build, lint, type checks, all 7 tools tests, and two cached runs of Ant Design's 78-test Checkbox suite. The PR is open; upstream CI requires maintainer approval.

• Checkbox.Group #59217 and Anchor #59211: submitted commit-specific approvals after base-versus-head reproductions, independent boundary probes, complete component suites (78 and 96 tests), and 42 successful remote checks per PR.

I contribute beyond authored patches by reproducing issues, checking duplicate work, reviewing exact commit heads, and helping maintainers distinguish source regressions from external CI or deployment gates.

Recent examples:

• Ant Design Pro dependency security #11933: compared current base/head audit graphs, verified the critical and targeted alerts were removed, then ran the clean install, 54 tests, lint, type-check, and production build before exact-head approval.
• Ant Design Transfer #59166: reproduced the stale-selection failure on the base commit, validated 53 tests and 289 adversarial key signatures, then approved the exact head.
• Ant Design Input.Password #59168: proved the controlled-state regression on the base commit and verified controlled, keyboard, callback, and uncontrolled-transition boundaries before approval.
• Ant Design Splitter #58978: validated localization, fallbacks, custom-icon precedence, RTL, and vertical behavior across all bundled locales.
• React Component Trigger #622: verified a corrected concurrent-render regression against the exact updated head instead of relying on obsolete review evidence.

1. Establish the public contract and reproduce the problem independently.
2. Search existing Issues, PRs, and dependency repositories before starting work.
3. Keep the patch small and add a regression that fails on the exact base.
4. Run the focused suite, relevant static checks, and boundary probes.
5. Revalidate the exact head after feedback or a rebase.
6. Use signed commits and disclose AI assistance in public contributions.
