FAQ
Can you build a complete SaaS product?
I can build a defined MVP or clearly scoped set of features. A complete SaaS platform usually requires multiple milestones, so please contact me before ordering for a custom plan.
Can you add payment integration?
Payment integration may be available as a custom feature. Please send the payment provider, required workflow, and test-mode requirements before ordering.
Can you work on my existing application?
Yes, depending on the technology, code quality, documentation, and access available. Please send the repository structure and requested changes before ordering.
Will you provide the source code?
Source-code delivery depends on the selected package and agreed scope. Third-party libraries, APIs, hosting, and paid services remain subject to their own licenses and costs.
Do you provide hosting and domain registration?
I can provide deployment guidance or help configure an existing service, but the hosting, domain, and cloud accounts should remain owned by you.
Can you build a mobile application?
This Gig is for web applications. A responsive web app may be possible, but native Android or iOS development should be discussed separately.
