How does the timezone difference work with United States?
Live overlap through 12:30 PM Eastern / 9:30 AM Pacific every workday — standups and demos happen in your morning, and finished work lands overnight. Weekly demos are scheduled in your hours, and async updates keep the thread moving between them.

You engage an independent contractor — W-8BEN on file, USD invoices via Upwork or direct wire, no payroll, benefits, or EOR setup. Payment terms are milestone-based — no large upfront commitments.
Who owns the code and IP?
You do — completely. Work happens in your repositories where possible, IP assignment is written into the SOW, and there is no lock-in: everything is documented so any developer can take over.
Can you ship mobile, web, and AI together?
Yes. React Native + Next.js + Python (FastAPI) + RAG/AI agents under one senior owner — ideal when your United States team needs to ship mobile, web, and AI without coordinating multiple vendors.
What happens after launch?
Most clients keep a monthly care retainer: dependency updates, store submissions, monitoring, and a priority line for fixes and small features. You can also hand off entirely — the documentation is written for that.
