FAQ
Why should I contact you before placing an order?
Every project is unique. Please contact us before ordering so we can review your requirements, recommend the right package, and provide an accurate quote and timeline.
Is VAPT security testing included in my package?
It's included free only in the Enterprise package. On Core and Secure, VAPT is available as a paid add-on, priced per assessment — message me with your scope and I'll quote it alongside your package.
Do you actually perform VAPT, or is that just a buzzword?
We run OWASP Top 10–based testing on the application and deliver a written report of findings and fixes — not a generic automated scan repackaged as "security testing."
Can you build both a web portal and a mobile app that share data?
Yes. We build the backend/API once, then connect a web portal and a React Native app to it, so your data and business logic live in one place. Mobile app development is included in Enterprise and available as an add-on on Core/Secure.
Will I own the code, and do you sign an NDA?
Yes to both. Full source code and IP ownership after final payment. NDA signed on request before we discuss your idea.
Do you deploy to my own cloud account?
Yes — Azure, AWS, or Windows/IIS, deployed under your own accounts. No vendor lock-in.
What if my project is bigger than the Enterprise package?
That's normal for larger platforms. Message me with your requirements and we'll scope a custom quote — the Enterprise package is a starting point, not a hard ceiling.
Do you provide support after delivery?
Yes — every package includes a support window, and we offer ongoing maintenance beyond that on request.
Do you develop complete software solutions?
Yes. We build complete business solutions, including web applications, admin dashboards, APIs, AI integrations, and mobile applications.
Can you develop Healthcare Software?
Yes. We have experience developing patient portals, healthcare platforms, compliance systems, and medical software solutions.
