FAQ

How much does a project cost?

It depends on scope. Most projects I take on range from $5,000 to $50,000+. A simple MVP might be on the lower end, while a complex platform with many features will be higher. We discuss budget in the discovery call and I provide a detailed estimate before we start.

How long does it take?

A typical MVP takes 2-8 weeks depending on complexity. More complex projects take longer. I provide a realistic timeline upfront and keep you updated as we progress.

Do you sign NDAs?

Yes, absolutely. I take confidentiality seriously and am happy to sign NDAs or other legal agreements your company requires.

Can you maintain/support the app after launch?

Yes. I offer post-launch support, maintenance, and feature development. We can set up an ongoing retainer or hire me as needed.

What if I need custom database design?

That's a core strength. I can design databases for scale, optimize queries, and build APIs that work efficiently.

Can you work with my existing codebase?

Yes. I can integrate with existing Next.js, React, Node.js, or other JavaScript projects. If it's a different tech stack, I can learn it or recommend whether it makes sense.
