Before we get started.
Can we start with just an idea?
Yes. Consulting helps map the requirements and define a realistic first version.
Are package prices final?
No. The current prices are examples. A final quote depends on the scope and requirements agreed during our discussion.
What about maintenance?
Maintenance, fixes, and ongoing development are discussed as a separate part of the proposal.
How long does a project take?
It depends on the scope. A simple website usually takes a few weeks, while an app is built in stages around the highest-priority workflows.
What happens after the app is finished?
I help with handover, documentation, and release preparation. Maintenance or further development can be discussed separately.
Are domain, hosting, backend, and store publishing included?
Not automatically. Third-party services, store accounts, domains, hosting, and backend needs are discussed per project scope and listed in the proposal.
How does payment work?
Payment milestones are agreed based on the scope and project stages before work begins.
Do I receive the source code and documentation?
Source code handover and documentation are discussed in the project scope and included in the agreement.
