Expo, React Native Specialist for Build Failures

I require an expert in Expo and React Native to troubleshoot a persistent "Build Failed" error in my project. The issue seems to be rooted in errors in my build configurations. The ideal candidate will be skilled at spotting and resolving these types of configuration issues and have a track record of successful React Native project builds. Experience using Expo is additionally necessary for this job. I look forward to receiving your proposals, ideally supported with examples of previous similar work rectifying build configuration issues.
