What people ask us.
Can you take over an existing codebase?
Yes. We start with a short review and tell you what we'd keep and what we'd change before we quote.
Who owns the code?
You do. The code lives in your repository, with documentation and a handover so your team, or another one, can carry on.
Do you build in Mongolian?
Yes. We build in Mongolian and English, and the products we ship can switch between the two.
Priced by scope or by the hour.
A fixed-scope proposal for a defined build, or an hourly rate for ongoing work, lower for engagements of several months.
