Sheriffdeen Adewale Jimoh

I’m a dynamic IT Specialist with over 14 years of expertise in hardware engineering, software deployment, and network infrastructure, with a Cisco CCNA certification. I focus on keeping systems stable and available—driven by a commitment to ensure 100% system uptime.

As Founder & Lead IT Technician at PCFIXKING COMPUTERS, I launched and managed a full-service IT consultancy for high-end hardware repairs, system upgrades, and software architecture. I built a 50+ recurring customer base within the first year, delivering a 98% resolution rate on complex hardware failures.

In my recent and earlier roles as an IT Technician / Call Agent, I administered technical support across multi-department operations while maintaining hardware integrity and network stability. I reduced technical downtime by 20% through proactive hardware maintenance and resolved high-priority network connectivity issues using CCNA principles to ensure secure, continuous access to cloud-based tools.

I also strengthened real-world environments through end-to-end IT lifecycle support—procurement, setup, and maintenance—plus LAN/Wireless optimization to increase internal workflow efficiency. From university laboratory IT support and data backup compliance to remote troubleshooting of Microsoft application suites, I consistently combine hands-on diagnostics with disciplined execution.
