I've supported customers at Telecel Ghana by diagnosing connectivity, SIM, device, and service issues while maintaining accurate resolution records and escalating complex network faults.

My data analytics work combines Excel, Power BI, SQL, and Python to collect, clean, analyze, and visualize data for actionable recommendations. I've built interactive dashboards and reports that communicate data-driven insights clearly.

In a store database project, I designed a relational schema for multi-category inventory and wrote SQL aggregate queries to extract inventory valuation and stock-density statistics.

I've also analyzed Gen Z social media usage and student academic data, processing 50,000 records and developing recommendations around technology exposure, anxiety, skill retention, and GPA growth. My cybersecurity exposure includes Kali Linux assessments, passive reconnaissance, Linux command-line operations, and Bash scripting.
