Help me keep shipping backend and systems engineering work.
I'm Shirong Lu. I build practical public assets around Go, Java, distributed systems, RPC, infrastructure-oriented engineering, and reusable backend tooling. If my repositories, code contributions, templates, or engineering notes have saved you time, the fastest way to support that work is to scan the QR codes below or book a lightweight async review. I also offer compact feedback on GitHub profile packaging, public repo positioning, README polish, and resume sites.
Ways your support helps
I want to keep shipping practical public assets rather than half-finished personal experiments. Support helps me spend more time on things that are genuinely useful to backend and systems engineers.
- improving starter templates and developer tooling
- publishing more backend / systems learning material
- shipping more code fixes and implementation-oriented open-source contributions
- turning rough internal ideas into reusable public repositories
If you want to support my work without paying, that still helps a lot:
- star and share my repositories
- link my projects to other backend engineers
- open issues with concrete suggestions
- reference the projects in communities, blogs, or newsletters
Small support is enough
If one repository, checklist, template, or doc contribution saved you time, a small direct tip is already meaningful.
Any amount is appreciated. If you are supporting because of a specific repo, feel free to mention it in the payment note.
WeChat Pay
Scan to support my open-source work directly.
Alipay
Scan to support templates, code contributions, and engineering notes.
One lightweight async review = ¥99
The simplest way to support practical open-source work and get something concrete back.
- GitHub profile / pinned repos — positioning, proof-of-work ordering, and signal cleanup
- Public repo README — title, description, setup flow, architecture framing, and CTA polish
- Resume site / portfolio page — wording, credibility, and conversion fixes
- Scope — one public profile, repo, or page per request
- Step 1 — pay via WeChat Pay or Alipay
- Step 2 — email the public link(s) plus a payment screenshot to happysnaker@foxmail.com
- Step 3 — get compact, prioritized async feedback with concrete edits and fixes
- Bundle option — ¥199 for a GitHub profile + one repo README + one resume-site / landing-page packaging pass
Paid support / collaboration
If you want to support my work and also get something useful back, these are the fastest options.
- ¥19.9 — tip for a repo, article, checklist, or doc contribution that saved you time
- ¥49.9 — thank-you support for interview prep material, backend checklists, or system design notes
- ¥99 — one lightweight async feedback request on a public GitHub profile / README / repo positioning / resume site
- ¥199 — bundled GitHub profile + one repo README + one resume-site / landing-page packaging pass
- After paying, you can mention the repo or page that helped you in the payment note.
- Best fit for interview packaging, public repo positioning, and polishing technical assets so they feel more credible.
- If you want lightweight paid feedback, contact me by email: happysnaker@foxmail.com
- I currently accept support through WeChat Pay and Alipay only.
