FAQ
Common questions
How fast can you deliver?
A landing page usually takes 3–5 days, a multi-page site 1–2 weeks, a tool or bot 2–7 days. The exact timeline is in the written scope.
Do I own the code?
Yes. After final payment you get the full repository, accounts and documentation.
How do we communicate?
Async and in writing: Upwork/Fiverr messages, email or Slack, with daily progress notes and staging links. Every decision is documented.
What about revisions?
Two free revision rounds per milestone. Anything outside the agreed scope is quoted before work starts.
Is there a warranty?
30 days of free bug fixes for anything within the agreed scope.
