Real-world engagements this covers
A typical United States brief
A Series A SaaS team in New York adding a React Native companion app to their web product — Stripe billing, SSO, push notifications, and App Store review handled end to end.
Production API from a spec
OpenAPI-documented endpoints with JWT auth, rate limits, structured logging, and green CI — deployed to your cloud with zero-downtime releases.

How does the timezone difference work with United States?

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.
