I work across the overlap of **system administration, MSP support, hosting, cloud infrastructure, website operations, networking, security, and business IT**. My background is not limited to WordPress or web hosting. I support the full environment around a business: **servers, websites, cloud platforms, DNS, email, backups, networking, VoIP, security, and day-to-day technical operations**. That includes both **Linux and Windows systems**, web infrastructure, and the kind of mixed environments most small and mid-sized businesses actually run. Over the last year I’ve worked hands-on with: * **Linux server administration** for hosting, websites, web applications, mail, backups, and infrastructure services * **Windows administration and MSP support**, including business systems, troubleshooting, user support, updates, and general infrastructure maintenance * **Cloud hosting and website infrastructure** across VPS, dedicated servers, shared hosting, and managed WordPress environments * **Cloudflare, DNS, SSL, CDN, WAF, and security hardening** * **Website migrations, server migrations, and platform moves** with minimal downtime * **Malware cleanup, incident response, hacked website recovery, and post-incident hardening** * **Email troubleshooting and deliverability**, including **SPF, DKIM, DMARC, DNS records, SMTP issues, and mailbox migrations** * **Backup systems, disaster recovery planning, uptime troubleshooting, and production incident response** * **Network and office infrastructure support**, including **Ubiquiti environments, firewall/router changes, Wi-Fi troubleshooting, and site-to-site / business connectivity work** * **VoIP and communications systems**, including **3CX deployment, support, and troubleshooting** * **Website maintenance and development support**, especially where the issue crosses between code, hosting, DNS, Cloudflare, and server infrastructure I’ve worked with infrastructure and platforms including: **Cloud & Hosting:** Vultr, DigitalOcean, OVHcloud, Hetzner, Contabo, Cloudways, WP Engine, Pressable **Server Panels & Hosting Platforms:** CloudPanel, Enhance, cPanel, Plesk, DirectAdmin **Operating Systems & Server Work:** Linux administration, Windows administration, web stack support, mail systems, backups, monitoring **Web Stack:** Nginx, Apache, MySQL, MariaDB, Redis, Varnish **Networking & Security:** Cloudflare, DNS, SSL, WAF, malware remediation, firewall/security hardening **Business IT / MSP:** Microsoft 365 / mail support, workstation/server troubleshooting, backups, patching, business support workflows **Networking / Voice:** Ubiquiti, 3CX **Web / CMS Support:** WordPress, hosting-side troubleshooting, migrations, maintenance, performance optimization A lot of my work sits in the space where **web, hosting, infrastructure, and business IT meet**. For example, a website issue may actually be a DNS problem, a mail issue may be caused by a server misconfiguration, a migration may involve Cloudflare, SSL, mail routing, and application fixes, or a hacked site may require both website cleanup and server-level remediation. That’s where I’m most useful: when the problem is not just “fix this website,” but **understand the whole environment, identify the real cause, and fix it properly**. I’m comfortable stepping into ongoing MSP-style support, one-off infrastructure work, migrations, hosting/server troubleshooting, Cloudflare projects, website incidents, email problems, and mixed business environments that rely on both **Linux and Windows systems**. If you need someone who can handle **servers, hosting, websites, DNS, email, Cloudflare, security, networking, Ubiquiti, 3CX, and day-to-day infrastructure support**, I’d be happy to discuss the project.
