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.
| Project | What it does | Verifiable entry points |
|---|---|---|
| BenchLineage | Records experiment provenance, calibration, uncertainty and evidence, with portable ELN import/export. | PyPI · v0.3.5 · five accepted ELN contributions |
| WheelWhy | Explains why a Python wheel matches or misses a declared interpreter and platform; it is not a full pip or uv resolver. | v0.3.1 · external feedback and fix · upstream follow-up |
| ColdShelf | Builds a private searchable catalog of unplugged drives, including snapshots, duplicate evidence and physical-location notes. | latest release · quick start · limitations |
| VulnFuse | Correlates findings from SARIF, Trivy, Grype, Snyk, CycloneDX, OSV and CSV without hiding merge blockers or scanner disagreement. | browser workbench · v0.4.24 · security model |
| TermScope | Plots Arduino, ESP32 and STM32 telemetry in a terminal over serial, pipes or SSH, with CSV record/replay. | PyPI · v0.4.1 · hardware reports wanted |
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
.elnfixture and mapping. It passed the upstream schema and validator checks and was approved and merged. - Merged: TheELNFileFormat PR #153
clarifies
@type,additionalTypeandgenrein the public specification. It was approved and merged, closing issue #105. - Merged: TheELNFileFormat PR #154
makes parameter checks handle array-valued
DatasetandFiletypes, with regression cases for both invalid and valid nodes. It was approved and merged. - Merged: TheELNFileFormat PR #155
clarifies how child
Datasetrelationships 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. - 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.
- Open: cibuildwheel PR #2966 removes an unconditional NuGet fallback source and adds regression coverage so configured package sources remain authoritative.
- 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
partswhile 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 and Keycloak #51697 are one accepted contribution each. They do not make me a module owner or core maintainer; cibuildwheel #2966 remains an unaccepted proposal. Self-submissions that list my own tools in curated lists are excluded from this section because they are promotion, not independent maintenance or adoption.
- I am the primary maintainer of the owned repositories featured above.
- I describe external work as merged or open contributions unless a project publicly grants broader responsibility.
- Synthetic/demo data is labelled as such; it is not presented as a user study or production deployment.
- Security and research tools publish assumptions and failure boundaries.
- Stars, downloads, users, benchmarks and testimonials are never fabricated.
Focused bug reports, real platform results and reviewable pull requests are welcome through each project's public Issues or Discussions.
