    Please don't contact me regarding hacked accounts. There is nothing I can do and it's illegal to try and hack them back. Sorry! For over 10 years my greatest passion has been cyber security. For the first 6 years I worked for NCC Group, the largest cyber security consultancy in the world and gained a wide range of skills and experience working for high street banks, global corporations and UK government ministries. I've now moved on and have started my own business, my greatest passion is helping small and medium sized businesses fix their security problems. I eat, drink and sleep cyber security. I have experience testing a wide range of technologies, including but not limited to web applications, internal networks, external networks, mobile applications, network devices and Wi-Fi. Having a broad range of experience allows me to rapidly place in context of the asset I'm testing within the clients environment. My focus is on helping web and mobile developers, network administrators and business owners ensure their products adhere, not just to best practice but to the highest security standards. By using a combination of manual and automated testing I am able to produce results in a timely and cost effective manner. I assist with remediation by providing advice on which areas of vulnerability to focus on first and how best to implement fixes. I have a track record of understanding highly technical security issues and being able to convey them to both a technical and management audience. I'm always happy to discuss client requirements and work with them to identify the best methods to achieve their objectives. As part of the process, I offer a pre and post engagement call to ensure we are a perfect match and that I have achieved your goals.

    As an experienced IT Support Engineer with a decade of expertise, I specialize in providing comprehensive IT services tailored to optimize and secure Microsoft 365 environments and Windows device management. My professional journey has been marked by a dedication to delivering seamless technology solutions, enhancing operational efficiency, and ensuring robust system performance. My multifaceted skill set and practical experience position me as a reliable partner for businesses seeking to leverage the full potential of their IT infrastructure. **Microsoft 365 Tenant and Environment Administration** In my ten years in the IT industry, I have developed a profound understanding of Microsoft 365 tenant administration. I have successfully managed environments with hundreds of users, ensuring smooth transitions during migrations and upgrades. A notable project involved the migration of a mid-sized company's email infrastructure from an on-premises Exchange server to Microsoft 365. This project included meticulous planning, execution, and post-migration support, resulting in zero downtime and seamless user experience. I am proficient in configuring and managing various Microsoft 365 services, including Exchange Online, SharePoint Online, Teams, and OneDrive for Business. My expertise ensures that businesses can leverage these tools for enhanced collaboration and productivity while maintaining strict security standards. **Windows Device Management** Windows device management is a critical component of modern IT infrastructure. My experience encompasses deploying, managing, and securing Windows devices across diverse environments. I have led multiple projects focusing on Windows Autopilot deployment, ensuring new devices are pre-configured and ready for end-users with minimal intervention. This approach significantly reduces the time and effort required for device setup and enhances user satisfaction. One of my key projects involved implementing Microsoft Endpoint Manager (formerly Intune) to manage a fleet of over 100 devices. This initiative included configuring compliance policies, setting up conditional access, and deploying applications remotely. The result was a streamlined device management process, improved security posture, and reduced support overhead. **PowerShell Scripting and Automation** Automation is at the heart of efficient IT operations, and my proficiency in PowerShell scripting has enabled me to deliver substantial improvements in this area. I have developed numerous scripts to automate routine tasks, such as user provisioning, mailbox management, and system monitoring. For example, I created a PowerShell script that automated the onboarding process for new employees, including creating user accounts, assigning licenses, and configuring email signatures. This automation reduced the onboarding time from potentially hours to minutes and minimised the risk of human error. **Comprehensive IT Services** Leveraging my extensive experience, I offer a range of IT services designed to meet the unique needs of businesses operating within Microsoft 365 environments. These services include: **Microsoft 365 Tenant Administration:** Comprehensive management of tenant settings, user administration, and security configurations to ensure optimal performance and compliance. **Windows Device Management:** Deployment, configuration, and management of Windows devices using Microsoft Endpoint Manager, ensuring secure and efficient operations. **PowerShell Scripting and Automation:** Development of custom scripts to automate repetitive tasks, improve efficiency, and reduce the potential for errors. **Security and Compliance:** Implementation of security policies, data protection measures, and compliance frameworks to safeguard business information. **User Support and Training:** Providing end-user support, troubleshooting, and training to maximise the adoption and effective use of Microsoft 365 tools and Windows devices. My commitment to staying up to date with the latest technological advancements ensures that I can provide forward-thinking solutions tailored to the evolving needs of businesses. By partnering with me, organisations can expect reliable, efficient, and secure IT operations, allowing them to focus on their core business objectives. If you're looking to enhance your IT infrastructure, streamline device management, or automate critical processes, I am here to help. Let's connect and discuss how I can support your business in achieving its technology goals.

    I have five years experience with delivering web application and infrastructure security reviews to a wide range of clients. I am currently waiting to sit the CSTL (Cyber Scheme Team Leader) Application exam. I am currently in full time employment and I am looking for contract projects that can be completed out of hours(1730 - 0900 and weekends) up to a maximum of 35 hours per week. I can fully manage your security project from scoping the project to delivering a comprehensive report covering all security issues found, along with remediation advice. Communication during testing is vital and I am able to summarise issues found daily either via a secure message or wash up call.
