09 · questions clients ask
How do we agree on scope?
After a 20-minute call and a short written brief you get a fixed scope and a date, so the plan does not grow on its own.
How long does it take?
A bot or a site usually takes 1–2 weeks, an AI feature 2–4 weeks, a web app or MVP 4–8 weeks. You see a working version early and then every week.
Who owns the code?
You do. At handover you get the repository, documentation, a runbook and tests, deployed to your accounts.
Will you sign an NDA?
Yes. Most of my paid work is under NDA, which is why client names on this site are hidden.
What happens after launch?
I stay available for fixes and changes. Ongoing support or a monthly retainer can be agreed separately.
Which languages do you work in?
English, Russian and Uzbek. My working day in Tashkent (UTC+5) overlaps Europe fully and US East Coast mornings.
Got something that has to work in production?
Email me two lines about the task: what it should do and when you need it. Calls work too, my day overlaps Europe fully and US East Coast mornings.
