What affects the price
Three things drive every estimate
I explain each line of a quote, so you can trade scope for budget where it makes sense.
01
Scope
Number of screens, user roles, platforms (web, iOS, Android, desktop) and integrations.
02
Timeline
A fixed launch date or a tight deadline may need extra capacity or a phased release.
03
Complexity
Offline sync, real-time features, legacy systems and compliance needs add design and test effort.
Payment and contracts

FAQ
Common pricing questions
Can you work with a fixed budget?
Yes. Tell me your budget up front and I will propose the scope that fits it, with clear notes on what moves to a later phase.
What happens if the scope changes?
For projects, changes are quoted separately and only start once you approve them. On a retainer, they are simply prioritized within your monthly hours.
Do you charge for the first call?
No. The intro call is free and without obligation. Afterwards you receive a written quote.
