Operations Manager at Alloyed leading eight teams and implementing new accounts for social media and programmatic clients.

El Salvador
Message

At Alloyed, I lead eight teams through eight team leads supporting U.S.-based agency clients. I own end-to-end implementation of new accounts and operational initiatives across social media and programmatic accounts.

I established SOPs, KPIs, and governance frameworks to sustain results after implementation. I use Smartsheet and Jira to track project milestones and dependencies.

For the CMI Media Services account, I led the Media Planning and Project Management teams, coordinating delivery, priorities, and resources across both functions. I also supported new account launches and operational transitions for U.S. client accounts.

At Avianca, I progressed through customer service, ticketing, connection protection, catering, and SOC operations. I also worked as a Backup Team Lead and Trainer, supporting onboarding, coaching, and daily operations; as an independent consultant, I support startups with process implementation and operational design.
