FAQs

Do you work like an agency or as a direct technical partner?

Direct technical partner. You work with the person shaping architecture, writing the code, and carrying delivery responsibility end to end.

What budget range should serious projects expect?

Most fixed-scope builds sit in the $3k to $15k+ range, while ongoing technical partnerships usually start around $3k per month.

Can you join an existing team or codebase?

Yes. Engagements can be greenfield builds, legacy modernization projects, or embedded delivery support inside an existing team.

Do you sign NDAs and support international billing?

Yes. NDA-first conversations are fine, and international projects can be structured with Stripe, Wise, or invoice-based billing.

Do you build AI and RAG systems over private business data?

Yes. AI delivery can include document ingestion, embeddings, vector retrieval, grounded responses, model integrations, and evaluation workflows.

Can I own the source code and hosting account?

Yes. Source-code ownership packages include the repository, deployment setup, documentation, and handover. Hosting accounts and recurring infrastructure charges remain in the client's name.
