My team and I recently created a POC for a company worth billions. It proved react native is a great new avenue for their product and we did it with a small team in a week. Then my team got hired to work for a long duration project.
I can’t share what it was due to NDA. I work for perficient.com which is a great consultant company. Reach out to me if your looking to hire a team for Expo / React Native work. Our teams commit 100% of their time only to your project.
