FAQ
Do I own the source code?
Yes, absolutely. You receive the full Git repository on delivery. The IP belongs to you - no vendor lock-in.
I built an MVP with Lovable / Bolt / v0 - can you take it over?
Yes. We regularly take over AI-generated apps, harden security, remove platform lock-in (e.g. migrate off Supabase Cloud) and make them production-ready. Message us with your repo.
Can you modernize my old/legacy application?
Yes. We migrate legacy PHP or monolithic apps to a modern, containerized stack - improving security, performance and maintainability.
How do you handle pricing for larger projects?
The packages are starting points. For bigger or unclear scopes, message us - we provide a precise custom offer after a short call. The Basic blueprint is a low-risk way to get a clear plan and quote.
Do you build multi-tenant / white-label SaaS?
Yes. We frequently build multi-tenant platforms with role-based access where each of your customers sees only their own data and branding.
Can you integrate with our existing systems?
Yes - ERP, CRM, payment providers, custom APIs, databases. Integrations are a core part of our work.
How fast can you deliver?
We use AI-assisted workflows to move quickly without cutting corners on architecture or security. Timelines depend on scope - the Basic call gives you a realistic estimate.
How does a project start?
For Standard/Premium, we recommend a short discovery call first so we understand your goals and give a precise plan. Order Basic, or message us directly.
