🔥 Full roast
🔥 4 years on GitHub, 92 repos, only 20 total stars, top project at 15; 3 of 10 popular-repo PRs rejected, half merged external PRs are doc/typo fixes, own repos are a star desert. Your PKU CS resume is
xuehaonan27 — 64.20/100 · NPC (Average · Unremarkable)
TL;DR: A diligent student developer with a handful of legitimate core PRs to big Rust repos, but a completely barren personal project wasteland and a 33% PR rejection rate that exposes how much of his external work is low-stakes polish.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 7.7/10 | Registered 4.01 years, contributions span 5 calendar years, last active 0 days ago — solid, consistent cadence for a student dev, no red flags here. |
| Original project quality | 9/18 | 38 nonempty original repos, 20 total stars across all personal projects, top project xuehaonan27/firecracker-rs-sdk sits at 15 stars with a 0.69 quality score. Your personal project graveyard is so dry even cacti wouldn't survive. |
| Contribution quality | 12.6/27 | 6 merged PRs out of 12 total, 3 maintainer-closed unmerged PRs, 1 author-closed external PR, 33% overall rejection rate, 50% of recent merged external PRs are doc-like (typo fixes, example corrections). Half your merged external PRs are window dressing, and a third of your popular-repo PRs got bounced — your contribution portfolio is half polish, half rejection letters. |
| Ecosystem / maintenance impact | 18.6/20 | 24 all-time contributions (10 PRs + 14 commits) to 7 popular repos including diesel-rs/diesel, transact-rs/sqlx, and moka-rs/moka, with verified samples showing 3 core code PRs and 1 doc-like PR. You've got real core code contributions to big-name Rust projects, not just doc tourism — this is the only part of your profile that isn't a star desert. |
| Community influence | 4.1/8 | 24 followers, following 23 accounts — you're one mutual follow away from a perfect simp circle, zero organic reach to speak of. |
| Activity authenticity | 12.2/17 | 530 contributions in the last year, no bot or farming signals detected. Your activity is genuine, just spread thin across a sea of low-impact work and empty repos. |
Red flags
- 33% overall PR rejection rate, with 3 of 10 all-time popular-repo PRs closed unmerged by maintainers — you're submitting a lot of PRs that aren't making the cut.
- All personal original repos have extremely low community adoption, with the top project sitting at just 15 stars and most at 0 — your home turf produces no value for the wider community.
- 50% of your recent merged external PRs are doc-like (typo fixes, example code corrections) rather than core engineering work, so your external contribution portfolio is half polish, half substance.
Score calibration No extra adjustment. The base score already prices in your mix of real core contributions, doc-heavy external PRs, and completely barren personal project footprint, with no missed qualitative signals to bump or haircut.
Verdict Normal, unremarkable student developer profile. You're not faking contributions, but you're also not making waves — your GitHub presence is a perfectly average open source resume, propped up by other people's popular repos and padded with low-stakes doc fixes.
