FAQ

Why no meetings?

I write code, you read commits. A 30-minute Zoom for a problem solvable in two Loom videos is a tax on both of us.

What about time zones?

I work Paris CET. I reply within 24h. If you need same-hour sync, I'm the wrong person.

What languages do you work in?

EN, FR, ZH — all async. Code is in English regardless.

Stack?

Next.js / React / TypeScript / Python / Supabase / Postgres / Stripe / Vercel / Notion API / Claude API / OpenAI API. I match your stack when it makes sense.

Refund policy?

7-day full refund if no commits land in your repo. After delivery, no refund — but I fix what's broken.

Do you sign NDAs?

Standard mutual NDAs, yes. Solo founder NDAs that demand exclusivity or IP assignment for life, no.

Got a scope in your head?

Send a 50-word email. I'll reply within 24h CET with a fixed price or a one-question follow-up. No discovery calls.
