I’m a cybersecurity and network security professional with hands-on experience across Fortinet, Qualys, and Imperva. I enjoy solving complex technical problems, improving security posture, and supporting clients through clear communication and reliable execution. My background includes firewall migrations, VPN optimization, troubleshooting performance issues, and delivering demos and presentations to clients. I also support pre-sales activities through BOMs, RFPs, and RFQs.

I’m driven, customer-focused, and always looking to grow my technical and professional skills while contributing to strong, secure, and efficient IT environments.

I have solid experience in cybersecurity and network security, working with Fortinet, Qualys, and Imperva across both technical operations and customer-facing environments. My background includes firewall migrations, VPN troubleshooting, security policy optimisation, and resolving performance issues. I also support pre-sales by delivering demos and presentations, compiling BOMs, and assisting with RFP/RFQ documentation. I bring a mix of hands-on technical expertise, strong communication, and a customer-focused approach to delivering secure and reliable solutions.

I hold a BSc in Computer Systems from Heriot-Watt University. I’ve strengthened my technical and pre-sales capabilities through multiple vendor certifications, including Imperva Sales and Pre-Sales, Qualys Pre-Sales and Implementation, and Fortinet FCF and FCA. This combination of academic training and vendor-specific skills supports my work across cybersecurity, network security, and solution design.
