I am an ICT Systems Specialist with over 10 years of experience in network infrastructure, system administration, and data analysis across banking, education, and telecommunications sectors.

I have a proven record of optimizing system performance — reducing operational downtime by 40%, achieving 99.7% average uptime, and cutting annual operational costs by ₦2.5M through automation and system optimization.

My recent certifications include Data Analysis and Visualization (NITDA 2024) and CFI coursework, and I am skilled in advanced Excel VBA, database management, cloud migration, cybersecurity best practices, and IT project management.
