FAQ

Frequently asked questions

What's the difference between a website and a web application?

A website presents information; a web application does work — logins, data entry, workflows, dashboards, billing. We build the latter (and make it as fast and polished as the former).

Which technology stack do you recommend?

For most business platforms: React front-end, .NET or Node.js APIs, PostgreSQL/SQL Server, deployed on Azure or AWS. We match the stack to your team, hiring market and scale — not to a fashion.

Can you build a SaaS product we can sell?

Yes — multi-tenancy, subscription billing, onboarding, admin consoles and usage analytics are core SaaS patterns we've shipped in our own products.

How do you ensure the app scales?

Stateless services, queue-based background work, caching, database indexing and load testing before launch — plus auto-scaling infrastructure so traffic spikes don't page anyone.

Can you modernise our old web app?

Yes. We audit the existing system, then either refactor incrementally (strangler pattern) or rebuild with a managed data migration — whichever is lower-risk for your business.
