Hi — I'm Randhir Jassal, the engineer behind PrepStack. I write everything on this site myself. Real responses, real human, no auto-replies.
Email: randhir.jassal@gmail.com LinkedIn: linkedin.com/in/randhirjassal
I'm based in India and check email on weekdays.
To help me respond faster, please pick the closest match:
| Subject prefix | When to use it |
|---|---|
| "Feedback" | Article suggestions, "you should cover X", or general thoughts |
| "Correction" | Found a bug, typo, or factual error in an article |
| "Question" | You're stuck on something covered in an article and want a follow-up |
| "Partnership" | Guest post, sponsorship, or cross-promotion |
| "Privacy" | GDPR / DPDP data-rights request (see the Privacy Policy) |
| "Security" | Vulnerability report — responsible disclosure welcome |
| "Hire" | Engineering consulting / architecture review work |
I aim to reply within 2–4 business days for general queries.
For privacy and security reports I respond within 24–48 hours.
If you want updates when I publish a new long-form article, you can subscribe to the newsletter (link in the site footer). One email per article, no marketing, easy to unsubscribe.
If you'd like to translate, mirror, or quote a substantial portion of an article, please email me first — short citations with a link back are always fine without asking (see the Terms).
To set expectations honestly:
Thanks for reading PrepStack. Drop me a line whenever something here helped — or didn't.
