From the information you’ve provided, I believe you are likely a qualified and competitive for the UCLA FEMBA Flex program.
One factor that's unclear, and would have a bearing on your competitiveness, is your work performance. Your role is appropriate for FEMBA and other programs at this level, however, it’s not just WHAT you do but your track record of advancement, leadership, and impact within your roles. The adcom will be looking to see that you’re a high performer within the given role -- and your application (resume, essays, recs) should portray such a record.
The GRE score is OK, and your academic track record is very strong. I expect that you’ve earned good grades in you independent courses.
Overall, to reiterate, assuming an impressive work performance and a strong application, I consider you to be a viable applicant to the FEMBA program.
