What I'm looking for

I’m looking for a role where I coordinate operations and manage high-volume enquiries to streamline workflows across teams. I’ll use Outlook/Teams and CRM automation to improve turnaround times, stakeholder communication, and customer satisfaction.

I’m a Business Operations and Administrative Coordinator and Administrative and Business Process Specialist with mid-level experience delivering operational support in academic and telecom settings. I’m known for translating messy day-to-day activity into clear processes, dependable timelines, and a consistently professional front-line experience.

At NUST Harold Pupkewitz Graduate School of Business, I supported operational workflows across 5+ departments and improved cross-functional efficiency by 22%. Through weekly briefings and concise email updates, I strengthened stakeholder communication and reduced clarification requests by 15%, while maintaining accurate records and handling sensitive information with discretion.

As a Web & Digital Solutions Consultant (self-employed), I manage client communications, consultations, and service delivery across multiple concurrent projects. I coordinate timelines, maintain deadlines, oversee administrative and enquiry management functions, and use Outlook and Teams to deliver customer-focused solutions that improve client satisfaction and retention.

I bring strong administrative fundamentals from NUST NGCL—front-line enquiries, scheduling, correspondence, accurate filing systems, and fast response handling using Microsoft Outlook. With experience managing high-volume communication and contributing to workflow optimization initiatives, I’m ready to drive administrative efficiency and stakeholder success with service excellence, confidentiality, and clear coordination.
