Electrical Engineering PhD researcher at CUHK. I maintain public tools for reproducible engineering, Python packaging diagnostics, local-first data work, and explainable security evidence.

I try to make each claim inspectable: public releases, runnable entry points, documented limits, and direct links to upstream work. A download counter or a self-submitted project listing is not presented as independent adoption.

See all repositories and published Python packages. The projects above are the small set I currently use to represent my maintenance work.

Recent owned-project maintenance includes VulnFuse PR #73, which closed issue #72 in v0.4.24 by preserving Trivy SARIF image identity for OpenVEX correlation, and TermScope PR #8, which closed issues #6 and #7 in v0.4.1 by tightening labelled-telemetry token boundaries. JSONXray PR #7 closed issues #5 and #6 in v0.2.1 by rejecting malformed streamed arrays. BenchLineage PR #20 closed issue #19 in v0.3.5 by adding explicit ELN data-license metadata, while SlowImports PR #6 closed issues #4 and #5 in v0.2.1 by preserving target failures and Unicode streams. These owner-authored and owner-merged releases demonstrate active maintenance; they are not external contributions or independent adoption.

• Merged: TheELNFileFormat PR #152 adds a reproducible BenchLineage-generated .eln fixture and mapping. It passed the upstream schema and validator checks and was approved and merged.
• Merged: TheELNFileFormat PR #153 clarifies @type, additionalType and genre in the public specification. It was approved and merged, closing issue #105.
• Merged: TheELNFileFormat PR #154 makes parameter checks handle array-valued Dataset and File types, with regression cases for both invalid and valid nodes. It was approved and merged.
• Merged: TheELNFileFormat PR #155 clarifies how child Dataset relationships are represented in the public specification. It was approved and merged, closing issue #116.
• Merged: TheELNFileFormat PR #156 validates the specification's single-root-folder archive requirement. It passed the upstream check and was approved and merged; related issue #67 remains open.
• Merged: CycloneDX Python PR #1028 encodes local XML-schema paths as file URIs and adds a regression test for package paths containing #. All 47 public checks passed; a project member merged it, closed issue #551 and released it in v11.11.2.
• Open: CycloneDX JavaScript PR #1507 maps string-valued package.json engine constraints to the official npm CycloneDX taxonomy and ignores malformed non-string values. I ran all 4,166 tests, lint, standards and dependency checks, Node/web/declaration builds, and a clean packed-tarball runtime probe. All four reported public checks pass. The PR remains open and unaccepted; it does not establish maintainer authority or independent adoption.
• Review: CycloneDX Python PR #1016 initially lost a strict-valid CycloneDX 1.7 relationship during model round trips. I reproduced the defect and requested bounded coverage; the external author implemented it. I reran 770 related and 6,994 full tests on exact head ea7d2ca, then approved that revision. The PR remains open and unaccepted.
• Review: CycloneDX Python PR #1015 adds CycloneDX 1.7 standardized algorithm-family and elliptic-curve identifiers. I ran 344 focused and 7,305 full tests, flake8, mypy, package builds, and a clean-wheel JSON/XML validation and downgrade round trip, then approved exact head fd0ec256. The PR remains open and unaccepted; this is review evidence rather than merge authority or maintainership.
• Review: CycloneDX Python PR #1007 removes quadratic dependency registration from Bom.validate(). I ran all 6,961 tests, exercised the complexity guard across 20 hash seeds, compared base/candidate equality counts, and generated strict-valid 1.6 JSON at 1,000, 2,000 and 4,000 components while preserving exact component and dependency reference sets. I approved exact head caa74d7; the PR remains open, and this is tested review evidence rather than assigned review duty, merge authority or maintainership.
• Review: CycloneDX Python PR #940 adds bounded, structured JSON/XML validation errors. On exact head ac93dbca, I ran 1,620 focused and 6,959 full tests and scanned all 359 repository JSON fixtures. The scan reproduced a misleading nested-error selection in 10 of 21 contextual errors, including the repository's mixed declared/concluded-license fixture. I requested a tie-aware selection and a regression. The PR remains open and conflicting; this is tested review evidence, not accepted code, assigned duty, merge authority or maintainership.
• Review: CycloneDX Python PR #935 introduces a side-effect-free ModelValidator, but removed the existing public Bom.validate() call despite the linked maintainer direction to deprecate it. Against current main, the call returned True; exact head 00df85b raised AttributeError. I ran 744 focused and all 6,965 tests, flake8, mypy, package builds and clean-wheel behavior probes, then requested a deprecated compatibility wrapper plus a legacy-caller regression. The PR remains open; this is tested review evidence, not acceptance, assigned duty, merge authority or maintainership.
• Review: python-docx-template PR #661 makes the intended license and test contents of source distributions explicit. I compared the published 0.20.2 source distribution with the exact PR head, rebuilt both package formats, ran 36 installed-wheel test scripts and the CLI path, and approved the third-party change. The PR remains open and unaccepted.
• Review: python-docx-template PR #642 adds CLI template-syntax validation and JSON reports. On exact head c1259ab, I verified source and installed-wheel behavior, all 36 non-runner scripts, flake8 and package builds, then requested changes because two rejected validation invocations printed errors but returned success exit code 0. This is actionable review evidence, not approval, acceptance or maintainer authority.
• Review: python-docx-template PR #648 preserves optional Subdoc imports while sorting package imports. I ran all 37 test scripts, flake8, package builds and clean-wheel environments both with and without docxcompose; normal and subdocument outputs rendered and reopened successfully. I approved exact head f583ed34; all 14 upstream checks pass. The PR remains open, so this is review evidence rather than acceptance or maintainer authority.
• Review: Argo CD PR #29175 proposed boolean parsing that diverged from bundled Dex v2.45.1. I reproduced three boundary failures and verified a strconv.ParseBool candidate with focused and full util/dex tests plus go vet, then requested compatible parsing and tests. This is actionable review evidence, not delegated Argo CD responsibility or acceptance.
• Review: pandas PR #66623 improved Arrow-string memory accounting in a clean installed wheel, but two exact MultiIndex memory tests failed, the public doctest expectation was stale, and the branch conflicted with main. I submitted a tested CHANGES_REQUESTED review on exact head ece0d447. The PR remains open and this does not establish pandas maintainer authority.
• Open maintainer-path work: python-docx-template PR #662 fixes escaped Jinja delimiters split across Word runs for issue #548, including the original attached document and Python 3.9/3.13 regression runs. I also triaged issue #627 with a two-page reproduction and an exact artifact request. The project owner publicly asks maintainer candidates to contribute first; these actions follow that path but do not grant me maintainer authority.
• Merged: Keycloak PR #51697 reports OID4VCI credential-request errors consistently and adds regression coverage for missing claims metadata and invalid proof timing. It fixed help-wanted issue #51692, received maintainer approval, passed the upstream check matrix and was merged into the default branch.
• Review: CycloneDX specification PR #1019 implements the schema defect I reported in issue #1018. I independently ran the Java, Node and Buf gates on its exact head, approved it, and closed my later duplicate #1020 to reduce maintainer work. The third-party PR remains open and unaccepted.
• Merged: eLabFTW PR #7267 adds the licensed BenchLineage v0.3.5 demo as a cross-producer ELN import fixture after a maintainer welcomed the proposal in issue #7263. A real PHP/MySQL import selected an experiment and preserved all 20 linked uploads. Maintainer NicolasCARPi approved exact head baeb6e37; all ten checks passed, and merge 77b941e1 placed the byte-identical release asset on default master. This is accepted external integration work, not independent user adoption or eLabFTW maintainer authority.
• Open: cibuildwheel PR #2966 removes an unconditional NuGet fallback source and adds regression coverage so configured package sources remain authoritative.
• Merged after maintainer feedback: tox PR #4022 provisions the requested tox version before reading version-specific configuration. I added exact tox l and tox c behavior coverage requested in review. Maintainer gaborbernat approved exact head 21de6da9; all 30 checks passed, merge c3f8d227 entered default main, and issue #4021 closed.
• Open: BuildKit PR #7038 makes history.maxEntries=0 explicitly disable build-history persistence. The focused integration test passed across nine worker variants and the approved fork workflow matrix is green; no maintainer has accepted it yet.
• Open: Airflow PR #71535 refreshes a stale local bare Git origin when a requested bundle tracking ref cannot be resolved. Focused, module, type, packaging and real promotion paths passed locally; the large upstream matrix is still running, so this is not reported as accepted or fully green.
• Open: Astropy PR #20234 rejects FITS tables with more than 999 physical columns before writing a partial file and adds the 999/1000 boundary regression. Astropy member pllim requested a plain-text changelog entry; I pushed the tested one-line change and resolved the sole review thread. The review was not an approval, and the PR remains unaccepted.
• Open: Kustomize PR #6224 adds legacy release-download support for pre-module tags and assets. A project member issued /ok-to-test, and all 23 executable source, platform and deployment checks pass. The official EasyCLA rerun still reports missing authorization, so this remains a blocked proposal rather than accepted work.
• Merged: SampleDB PR #91 fixes valid ELN imports that contain explicit ZIP directory entries while preserving rejection of genuine multi-root archives. It was merged into the upstream default branch; GitHub reported no reviews or checks for the PR.
• Merged: SampleDB PR #92 preserves flexible ELN metadata named parts while assigning collision-free keys to generated nested-Dataset relationships. It was merged into the upstream default branch; GitHub again reported no reviews or checks.

The five accepted TheELNFileFormat contributions make me a repeat external contributor there. SampleDB #91 and #92 make me a repeat external contributor to that separate project; CycloneDX Python #1028, Keycloak #51697, eLabFTW PR #7267 and tox #4022 are one accepted contribution each. CycloneDX JavaScript #1507 is a separate open ecosystem contribution. They do not make me a module owner or core maintainer. CycloneDX Python #935/#940/#1007/#1015/#1016 and specification #1019 are review contributions; python-docx-template #661, #642 and #648, Argo CD #29175 and pandas #66623 are independently tested reviews, while python-docx-template #662 and cibuildwheel #2966 remain unaccepted proposals. The python-docx-template work follows a public candidate route but is not a maintainer appointment. The eLabFTW fixture is cross-producer integration evidence, not independent adoption. Self-submissions that list my own tools in curated lists are excluded from this section because they are promotion, not independent maintenance or adoption.
