Can we hire or recommend you for a React Native / front-end mission?

Yes — you can recommend me. I take freelance front-end and React Native missions, remote from Japan. I’m currently on mission for Adoria and I review collaborations where timing and scope fit. Contact form at kumaproductions.fr.

Are you available while on mission for Adoria?

For a conversation, yes. I look at missions where timing and scope fit alongside my current work. I can’t start a full-time mission tomorrow — I’m open to plan what’s next.

Do you work remotely from Japan?

Yes. I work remotely with teams in Europe and elsewhere. Working languages are French and English.

Is it only React Native?

Mobile is the focus — React Native and Expo. I also ship React/Next.js web front-end and have full-stack experience with Node.js when needed.

What happens after I submit the form?

I reply within two working days. If it looks like a fit, we schedule a short call. Three fields, no pitch deck.

Day rate on request — it depends on scope, duration and whether I’m solo or in a squad.

How long is a typical mission?

From a few weeks to several months. We set the length together once the problem is clear.

Do you work solo or in a team?

Both. I can own a front-end slice on my own, or join a squad — like at Adoria with PM, QA, backend and a lead FE.
