DataEngineer Hub is a solo-maintained practitioner site. Most messages come from four places: content feedback (errors, outdated pricing, or broken syntax in articles, cheat sheets, or tools), tool bugs (a calculator result that looks wrong, a playground crash, a formatter that strips a keyword), guest-writing pitches, and sponsorship inquiries. All four are welcome. Replies are personal, usually within 24–48 hours on weekdays, India Standard Time.
Email is the fastest path for a technical correction. Put the article slug or tool URL in the first line, then the sentence or input that is wrong, then what you expected. Screenshots help for calculator bugs. Guest-post pitches and sponsorships can take up to five business days because they go through editorial review.
What to include so we can actually help
Corrections: URL, incorrect sentence or number, and the source you used to verify the fix (vendor docs, a query profile, a bill).
Tool bugs: the exact inputs, browser, and whether the result is blank, NaN, or just implausible versus a vendor list price.
Topic requests: the platform, the job you were trying to do, and what existing articles or cheat sheets did not cover.
Pitches: a one-paragraph outline plus two links to prior published work. Start from Write for Us.
Sponsorships: product, audience, and preferred month. Start from Advertise.
What we will not do
We do not provide paid homework, exam dumps, or private consulting through this form.
We do not sell email lists. A message here is used only to reply to you.
We do not accept unsolicited attachments or AI-spun article drafts. Original writing with working examples only.
We do not post anonymous corrections. If a guide is wrong, we patch it and note the change on the article when it is material.
If you want a weekly digest rather than a reply, use the newsletter page. For the person behind the bylines, see About.
