Hello, my name is Chris O'Rorke. Over the past 25 years, I have earned certifications in a wide range of Microsoft technologies, encompassing both server and desktop environments. In addition, I bring over a decade of hands-on experience configuring and optimizing Cloudflare. I currently manage 20 domains of my own under an enterprise-level Cloudflare account, with access to 24/7 emergency support. More than 75 clients trust me to oversee their Cloudflare configurations—from DNS management and performance tuning to security assessments and threat mitigation. I can help you fully leverage Cloudflare’s features to improve your website’s resilience and performance. I also specialize in email deliverability and domain reputation. My services include a detailed DNS audit to ensure proper configuration of MX, SPF, DKIM, DMARC, and BIMI records, followed by comprehensive inbox placement testing. When needed, I offer managed reputation repair targeting specific email providers, as well as supervised new domain warm-up. Additionally, I provide ongoing deliverability monitoring and proactive intervention, alerting you to any issues that could impact your outreach. I have extensive experience with platforms including Mailgun, Mailjet, SendGrid, Postmark, Kajabi, Campaigner, ActiveCampaign, Klaviyo, Amazon SES, and more. I'm also a partner with both Warmy and Folderly, enabling me to deliver robust solutions that enhance email performance and maintain a strong domain reputation. The best way to get started is by scheduling a consultation via my Upwork profile page, reaching out on UpWork Chat or inviting me to your job listing — I typically have next-day availability. I’m happy to answer any questions or provide more information if needed, and I look forward to the opportunity to work with you.
