FAQ
Full Stack Web Apps — common questions
What is full stack web application development?
It is the end-to-end creation of a web product—user interface, server logic, databases, and integrations—delivered as one cohesive system rather than separate frontend and backend projects.
How long does a full stack project take?
Timelines depend on scope. A focused MVP often ships in 8–14 weeks; larger platforms are phased across milestones with weekly demos.
Do you work with existing codebases?
Yes. We audit your repo, stabilize critical paths, and extend features without unnecessary rewrites unless architecture demands it.
Who owns the code?
You do. We deliver full repository access, documentation, and deployment credentials at handover.
How is Eternix Technologies different from hiring freelancers?
You get a coordinated senior team with shared standards across design, engineering, and delivery—reducing integration risk and communication overhead.
