  • Experience leading performance governance, incident management, root-cause analysis, change management, and production support within large-scale, mission-critical environments.

  • Strong analytical and problem-solving skills with the ability to identify root causes across application, middleware, operating system, storage, network, and infrastructure layers.

  • Proven leadership and communication skills with the ability to influence technical and business stakeholders, translate complex findings into executive-level recommendations, and mentor engineering teams.
