Questions we hear often.
How long does a typical project take?
It depends on scope. You get a timeline after discovery, and working releases every few weeks so you see progress early.
Who owns the code?
You do. Source code, documentation and access are handed over to you.
Can you take over an existing application?
Yes. We start with a code and infrastructure audit, then agree what to fix, keep or rebuild.
Can you work with our in-house team?
Yes. We can lead the build or work inside your team's process and tools.
What happens after launch?
We offer ongoing support and improvements as a managed service, or hand over fully to your team.
