Dear Hiring Manager,  

I hope this email finds you well and your systems running smoothly (or at least not on fire). My name is David Adewusi, and I’m a recent graduate from Oulton College with a Diploma in Systems Management and Cybersecurity. With over six years of IT experience under my belt ranging from system administration to cybersecurity and IT support, I’m excited to explore opportunities to bring my skills and enthusiasm to your organization.  

In my most recent role as a Systems Administrator and Cybersecurity Intern at NuFocus Group, I led phishing simulation campaigns, configured IT systems, and collaborated with third-party teams to ensure optimal performance and security. Before that, as an IT Support Specialist at AI Haktur IT Solutions, I supported 200+ users and achieved a 95% satisfaction rate because, let’s face it, people love it when their computers actually work.  

I hold a Bachelor’s Degree in Computer Science and certifications like CompTIA A+ and ISC² Cybersecurity. My expertise spans networking (TCP/IP, DNS, VPN, firewalls), operating systems (Windows Server, Linux), and cloud technologies (AWS, Azure). I’m also proficient in scripting with PowerShell, Python, and Bash, and I’ve worked with tools like SolarWinds, Wireshark, and Active Directory.  

What excites me most is the opportunity to contribute to an organization that values innovation, security, and collaboration. Whether it’s troubleshooting network issues, implementing robust security protocols, or optimizing system performance, I’m passionate about keeping IT infrastructure secure, efficient, and user-friendly.  

I’ve attached my resume for your review, and I’d love the chance to discuss how my skills and experience align with your team’s needs. Even if there isn’t an immediate opening, I’d be thrilled to connect and learn more about your organization’s goals and challenges.  

Thank you for considering my application. I look forward to the possibility of contributing to your team and helping keep your systems running smoother than a freshly defragged hard drive.  

Best regards,  
David Adewusi
