Do you work with clients in France?
Yes. I work remotely with France founders, product teams, and agencies — from Paris and Lyon to fully distributed teams. English-first communication, contracts via Upwork or a direct SOW.
How does the timezone difference work with France?
Live overlap across your full business day — roughly 9 AM to 6 PM CET. Weekly demos are scheduled in your hours, and async updates keep the thread moving between them.
How do contracts and invoicing work for FR companies?
Cross-border B2B invoicing with reverse-charge VAT — no French payroll or EOR required. 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 France 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.
