Who I am

I'm a results-driven Network Engineer with over eight years years in advanced network engineering, deploying, and managing large-scale network infrastructures across multiple African markets, including The Gambia and beyond.

My expertise spans standardising and automating network and security operations for distributed sites, leading cross-functional engineering teams, and orchestrating complex infrastructure projects from design to full deployment.

I'm passionate about scalable automation, zero-trust networking, and operational excellence — and I bring a track record of improving network uptime to 99% through disciplined redundancy and proactive monitoring.

Currently serving as Transmission Engineer at ZTE (worley), delivering enterprise-grade, multi-region connectivity designs while mentoring the next generation of network engineers.
