    ✅ I might well be the most adaptable all-round IT resource you've ever worked with. With nearly two decades of experience in IT, there's never been a problem I couldn't find a solution for. Whether it's an industry leading toolset, or an obscure line-of-business application, I find a way forward for your business. ✅ Hand-picked Upwork Expert Vetted (Top 1%) Earner with over $300k earned on the platform with a 5-Star Rating ⭐⭐⭐⭐⭐ 🧑‍💼Who Do I Help?👩‍💼 ➡️ Are you a start-up looking for some expert help on getting your tech up to scratch? I can help you worry less about your business's IT, so you can focus on doing what you do best. No matter what stage of start-up you are, I can offer an adaptable solution to meet and maximize your business's needs, whilst being mindful about scalability and cost control for you as your business grows. ➡️ Are you an existing SMB looking to supplement your existing IT support/project capabilities? Do you have issues finding experienced subject matter experts that can assist with high level L3/L4 support incidents related to IT infrastructure or software? I've remotely handled all kinds of emergencies as well as executed projects requiring the coordination of hundreds of people across a business. As a result, your team's experience grows during the engagement, and you are left with a solution that fits your requirements with a predictable budget and on-time with clear communication throughout. ➡️ Are you a small business in need of help with getting the most from Microsoft 365? So many businesses sign up for an account and leave their environments 'half used' when they could get so much more out of their subscription. Security, Compliance, Automation, Best Practice adoption, etc. - there's a ton that Microsoft's industry leading suite can offer as it evolves, so make sure you're getting the best bang for your buck. ➡️ Do you have concerns over the security of your Microsoft 365 environment? Cybersecurity threats are real, and they're here to stay. I can help your business become and remain vigilant, ensuring that you adopt security best practices, and maximize the abilities of the Microsoft eco-system to secure your data and your company's reputation. ➡️ Do you run a critical website or web application that you're having problems with? A number of my clients make their money from their presence on the web. If that's you, then make sure you're managing and maintaining your environment to ensure that it's secure, cost-effective, and well architected. This could be anything from a basic Wordpress website, through to a custom eCommerce solution that may not be maintained or deployed properly. If you rely on a website or web application for your livelihood, I can help you ensure that it's resilient, cost-effective and that best practices are followed for keeping it secure 🧠 My Core Expertise 🧠 ⚡️ Microsoft Windows Server ⚡️ Microsoft 365 ⚡️ Microsoft Intune ⚡️ Microsoft Azure Certified Administrator Associate ⚡️ IT Compliance & Governance ⚡️ AWS Certified Solutions Architect ⚡️ IT Project Management/Delivery ⚡️ Linux Support - Ubuntu, Apache ⚡️ Networking (DNS, DHCP, Routing, VPNs, Firewall & Security, VLANs) ⚡️ VMWare ESXi & Hyper-V ⚡️ Email Deliverability (DNS, SPF, DKIM, DMARC) ⚡️ Powershell/Automation ⚡️ Modern Workplace Adoption ⚡️ Web Hosting/SSL/DNS/Wordpress 🤔 Who am I? Originally from Canada, now living in Scotland, I am a Microsoft and AWS Certified Senior IT Resource & Project Manager with a focus on providing great service across the globe. My superpower is my ability to listen, learn, adapt and provide solutions to my clients' varied requirements. I embrace change and welcome opportunities for problem solving. It feeds my soul! I am a reliable and trustworthy IT pro with a wide array of experience across sectors and technologies (Education, Legal, Hospitality, Finance, etc.). My work tends to revolve around high-level problem solving and troubleshooting for all sorts of on-premise (Microsoft, VMWare, Linux) and cloud (Azure, Microsoft 365 and AWS) infrastructure. In addition to managing Windows and Linux servers, I have completed dozens of server migrations and troubleshooting all sorts of deep-rooted issues that go otherwise unresolved. In my 15 years with one of Scotland’s leading IT Managed Service Providers, I was the final point of escalation for technical issues, and as such I was privy to a wide array of interesting and frustrating issues that our clients faced. As such, I've developed and honed an ability to find creative and effective solutions for technologies I'd never previously encountered. I never submit for work that I can't deliver 100% on, and would welcome a conversation with you if you're looking to get some help with your IT setup. Thanks for your time!
