Lead and coordinate cross-functional project teams, ensuring alignment between Architecture, Network Operations, Information Security, and Client Services.
Facilitate and lead technical meetings, project reviews, and stakeholder updates to communicate status, risks, and decisions effectively.
Create and maintain comprehensive documentation for project plans, requirements, and post-implementation reviews.
Provide mentorship, peer reviews, and guidance to junior technical staff to promote professional development and technical excellence.
Participate in a 24x7 support rotation and provide escalation-level troubleshooting and leadership during incident response.
