FAQ
What information do you need before we start?
A short brief (problem you’re solving, main features, target users), any design references, and access keys you already have (e.g. OpenAI, Stripe). If you’re unsure, I’ll guide you through a quick discovery call.
Do I fully own the source code and IP?
Yes. All code, infra scripts, and documentation are transferred to a private repo under your account at hand-off. You retain 100 % intellectual property rights.
Which AI services can you integrate?
OpenAI, Anthropic, Google Gemini, Vapi voice, Pinecone/Supabase vector DB, and custom Hugging Face models. If you have another provider let me know. Most APIs are straightforward to add.
Where and how will the app be hosted?
Depends on your exact needs. If you have existing infrastructure I'll use your cloud provider. Otherwise it will be either AWS or Vercel.
How are bugs or revisions handled after delivery?
Each package includes a revision window (1, 2, or 3 rounds). Post-launch, I offer paid maintenance or ad-hoc fixes. For minor bugs introduced by me during the post-launch period are free.
Can you sign an NDA or work under strict confidentiality?
Absolutely. Send over your NDA or request my standard mutual NDA before we exchange sensitive details.
