Experience is the best teacher, as they say - 15 years of solid experience in the challenging but fun world of IT. My career started from humble beginnings. From Computer Teacher to IT Department Head - this is how I gained my experience and skills. I did not stop learning new things. I kept on pushing my limits and comfort zones. I want to end my brief overview with, "If you chase excellence, success will chase you." Hire me and you will never regret it :)

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.

As a former IBM TJ Watson fellow, I have got a great experience in System and Network Installation, Administration and Management. Back to France, I specialized myself in linux, teaching this topic as well installing servers and networks in-situ and as a remote basis. Since July 2000, I am a consultant specialized in these technologies : unix, linux, dns, dhcp, vlan, lan, mail servers, transparent migration, firewalls, load balancing and all kind of low level system and network issues in the OSI model. I can promote myself being concerned by the whole problem and by the whole compagny and not only to do the task as an isolated task. This is my way.
