⭐⭐⭐⭐⭐ "A+++. Highly recommended!! Nour was very responsive and dedicated himself to assisting with our AWS EC2 server migration which went smoothly and problem free. Nour was willing to chat over Zoom to facilitate quicker resolutions to the issues we were having. If you're searching for a quality Upwork professional with strong AWS, WHM and cpanel skills, look no further." ⭐⭐⭐⭐⭐ "NourEddine is a pleasure to work with. Despite our considerable timezone difference he was easy to work with. His Docker skills are next-level compared with others. Even when working slightly outside his area of expertise he proved himself innovative, adaptable, capable and persistent. Every time I came up with a new requirement, NourEddine found a solution. I'm very pleased with the end result, that being a fully functioning and well integrated production system. I can recommend NourEddine without hesitation." 🏆 Top Rated Plus • ✅ 2700+ work hours billed! • 60+ Projects 👨‍💻 Professional Linux Engineer for 6+ years with DevOps, Automation, and Cloud experience, solving problems and delivering results, for innovative startups as well as established unicorns! ● 📜👨‍💻 Red Hat Certified Engineer (RHCE: RHEL 8 and Ansible), Red Hat Certified Systems Administrator (RHCSA: RHEL 7), Red Hat Certified Specialist in Containers, and Terraform Certified Associate. ● ⚙️ System and software configuration, installation, deployment, optimization, troubleshooting, and automation. ● 🐧 Linux kernel management. ● OS 💿: Ubuntu, Debian, CentOS, Rocky Linux, Alma Linux, Red Hat Enterprise Linux (RHEL), Arch Linux, Manjaro, Proxmox, OPNsense, OpenWRT, Raspberry Pi OS, TailsOS, Whonix. ● Web and Proxy services 🌐: Apache, Nginx 🄽, Squid 🦑, Varnish, HAProxy, Taefik, Caddy, 3proxy, Gost. ● Databases and Datastores 💽: MySQL🐬, MariaDB, PostgreSQL🐘, Redis, Memcached ● Self-hosted apps and Control panels: Control Webpanel (CWP), cPanel, Plesk, Webmin, Cockpit, Nextcloud, Confluence, Jira, Wekan, Focalboard, Wordpress, Matrix Synapse, Mattermost, Dokkuwiki, Git, Gitea. ● DNS: Cloudflare, PiHole, Bind, AWS Route53, experience with SPF, DMARC, DKIM, PTR records for Email services. ● EMail ✉️: Mailu, iRedmail, Modoboa, Mailman, Postfix, Dovecot. ● Automation with Bash, Python, Web scraping, Selenium, and Ansible ● Virtualization, Containers and Cloud☁️:: Docker🐋, Kubernetes☸️, Rancher, K3s, RKE, QEMU/KVM, LXC, Proxmox VE, VMware ESXi, Hashicorp Packer, Hashicorp Terraform. ● Cloud Providers ☁️: Microsoft Azure, AWS, GCP, DigitalOcean, Vultr, and Hetzner. ● Object Storage 💾: AWS S3 and Wasabi ● Secrets & Certificates 🔏: SSL Self-signed Certificate and Certificate Authority, Let's Encrypt ( ACME.sh, Certbot, others), SSH PKI, Vault. ● Networking 🕸: TCP, HTTP, HTTPS, SSH, FTP, SFTP, SMTP, IMAP, POP3, FTPS, DNS, TLS, WebSockets, Tor onion routing, ngrok, ebtables, iptables, firewalld, iproute2, NetworkManager, netplan. ● VPN 🔏: OpenVPN, Wireguard, Tinc VPN, Outline VPN, OpenConnect, Anyconnect. ● Web scraping 🌐🕷️: Python requests, scrapy, beautiful soup, lxml, selenium. ● Development with Python 🐍, Bash scripting, Flask, SQL, HTML, JQuery, and JSON. ● Packaging 📦: Rpm, Deb, and Pacman.
