Fix an Android program built on Couchbase and Google Map

I have an Android app built with Google Map features and some part running on Couchbase Lite. We use CouchbaseLite to synchronize data with our backend using Couchbase Sync Gateway. We have encountered some issues with this program 1) App crashes when running Google Map and Couchbase Lite DB is accessed 2) Data syncing - not accurate. some data not synced correctly. We are looking for developer with experience on Couchbase Lite and Couchbase Sync Gateway who can assist in solving this issue. Interested candidates need to have experience with Couchbase Lite and preferably Google Maps. Two milestones - 50% upon problem solved (proved by providing apk to test), 50% upon delivery of source code.
