Lead Application Engineer at NBCUniversal supporting IBM Maximo and MAS 9, including a Maximo Mobile rollout for Universal Studios Hollywood.

At NBCUniversal / Universal Studios Hollywood, I support enterprise IBM Maximo 7.6 and Maximo Application Suite 9 environments across Universal Studios Hollywood, Universal Orlando, and Universal Studios Japan. I collaborated on deploying Maximo Mobile 9 for approximately 700–1,000 Hollywood users, enabling daily and nightly inspections ahead of the MAS 9 migration.

I supported the Maximo 7.6.3-to-MAS 9 migration, with primary responsibility for transferring and configuring existing Maximo Mobile functionality in the new environment. I also coordinate migration packages across development, QA, staging, and production, and troubleshoot application issues using SQL Server and DB2.
