FAQs

How long does it take to build an MVP?
Typical MVPs take 2–6 weeks depending on scope, integrations, and design depth.
Do you provide backend & APIs?
Yes. I design secure APIs (Node.js), databases, auth flows, and deploy on AWS/GCP/Azure.
Will you publish the app to App Store & Google Play?
Absolutely. I handle builds, provisioning, screenshots, ASO basics, and submissions.
What about post-launch support?
Monitoring, crash analytics, updates, and performance tuning are available in support plans.
