Hello, I have plenty of experience with analysing crash logs, heap dumps etc. I know how to use industry standard open source profiling an analysing tools, such as async, JFR, JMC and Eclipse MAT. Of course I can also share this knowledge with your dev. The 10 billable hours greatly limits what can be done in that much time, but I'll leave this for the chat.
