Frequently Asked Questions
How long does custom software development take?
An MVP takes 6–10 weeks. A full SaaS platform takes 3–6 months. We use agile sprints with weekly demos so you see progress throughout.
What is your tech stack for custom software?
We use React + TypeScript for frontend, Node.js + PostgreSQL for backend, and AWS for deployment. We also work with Next.js, React Native, and Python for specific needs.
Do you sign NDAs?
Yes. We sign comprehensive NDAs before any project discussion. All code is exclusively yours — we use private repos and zero third-party sharing.
What is fixed-price development?
Fixed-price development means we agree on scope, timeline, and cost upfront — no surprise invoices. You know exactly what you're getting and when.
Do you provide post-launch support?
Yes. All projects include 30 days of post-launch support. Extended support packages are available for ongoing maintenance, feature additions, and monitoring.
