🔥 Full roast
🔥 With 20 of your 22 repos being forks and your 2 original projects stuck at a combined 2 stars, you've dumped 90% of your 386 PRs and 361 commits into Apache Gravitino alone, treating GitHub like a con
mchades — 72.10/100 · SOLID (Solid · Trustworthy)
TL;DR: A high-volume, trustworthy contributor to major open-source projects whose personal repo portfolio is a barren wasteland — reliable for others, inert on their own turf.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | Registered 9.48 years, active for 10 years with last activity 5 days ago — no maturity issues to speak of. |
| Original project quality | 7.2/18 | Only 2 original repos, top project mac-browser has 2 stars, total original star count is 2 — your own projects can't even get your closest friends to hit star. |
| Contribution quality | 26.9/27 | 463 merged PRs out of 522 total, 8 maintainer-closed unmerged, 35 self-closed external PRs, 10 self-closed own-repo PRs, 2% rejection rate — your PRs get merged, not bounced, even when you close a few yourself before they're done. |
| Ecosystem / maintenance impact | 16.2/20 | All-time 419 PRs + 384 commits across 3 popular repos with ~29k combined stars (apache/druid, StarRocks, apache/gravitino); verified samples show substantive code, feature, and test work, not just doc polishing. |
| Community influence | 5.1/8 | 25 followers, 9 following — your influence is limited to the small circle that cares enough to follow, and you don't follow many back either. |
| Activity authenticity | 16.7/17 | 1534 contributions last year across 4 activity types, 10 active years — you're not a bot, just an extremely consistent contributor to other people's projects. |
Red flags
- 20 out of 22 public repos are forks, with only 2 original projects that have a combined 2 stars — your personal repo portfolio is a ghost town with no user-facing value.
- 97% of your all-time high-impact PRs target a single external repo (apache/gravitino), an unusually high concentration that leaves your contribution profile lopsided.
- 380 of your 419 popular-repo impact PRs fall outside the verified file-level sample, creating a coverage gap for a large chunk of your claimed high-impact work (this is a visibility note, not a score penalty).
Score calibration No extra adjustment. The base score already applies the appropriate penalty for your limited original project footprint, and your verified engineering contributions to major projects are strong enough to avoid any impact quality cap.
Verdict Normal. You're a reliable, high-volume contributor to major open-source projects with no trust red flags, but your barren personal repo portfolio and extreme single-repo concentration keep you from breaking into the top tier.
