Ahmed A.

I bring 20+ years of systems & cloud experience and have completed 300+ migrations, built CI/CD pipelines, and deployed production infrastructure for startups and enterprises. I focus on reliable, secure, and automated cloud platforms (AWS/Azure). Core skills & outcomes: Infrastructure as Code (CDK/Terraform), CI/CD (GitHub Actions/Jenkins), container orchestration (Kubernetes/EKS), RDS and database migrations, monitoring & cost optimizations. Example results: reduced deployment time by 80%, migrated 300+ WordPress sites with <1% downtime, and automated backups and recovery workflows. I’m available for high-value DevOps projects and offer phased delivery: audit → implement → harden → handover. Let’s discuss your goals and I’ll recommend a clear plan and timeline. I’ve worked with banks, hosting companies, and high-security environments—delivering infrastructure solutions that are battle-tested, optimized, and built for scale. 🔧 Core Skills: --🔹 Linux system administration (Ubuntu, CentOS, RedHat) --🔹 Docker, Portainer, Compose stacks --🔹 CI/CD pipelines (GitHub Actions, Azure DevOps) --🔹 Cloud architecture (AWS, Azure, Hetzner, Contabo) --🔹 VPNs, firewalls, and secure remote access --🔹 Server migrations with zero downtime --🔹 Monitoring, backups, and performance tuning 🧠 AI & LLM Expertise --🔹 #LLM Fine-Tuning (e.g., LLaMA, GPT-J, Mistral) --🔹 Model deployment via API or UI --🔹 Vector DBs (Weaviate, Chroma) --🔹 Prompt engineering and context optimization ☁️ Cloud & Infrastructure Automation --🔧 Full-stack deployments on #AWS, #Azure, #Hetzner, #Contabo --🔧 Dockerized hosting (Coolify, Portainer, custom Compose stacks) --🔧 Self-hosted services: dashboards, Git servers, monitoring --🔧 #CI/CD pipelines with zero-downtime rollbacks 📡 DNS, Email & Web Routing --🛰️ Complex #DNS setups (Cloudflare Workers, hybrid path routing) --📧 Email security: #SPF, #DKIM, #DMARC, PTR, blacklist delisting --🌐 Hybrid apps: WordPress on /blog, React or Vue on root 🐧 System Administration (Linux & Windows) -- M365 --🛡️ Install, harden, monitor full server lifecycle --💾 WHM/cPanel migration, cron jobs, SSL, mail servers 🪟-- Windows AD and #Exchange migrations 🔐 Networking & Security --🔐 VPN setup (OpenVPN, WireGuard, IPSec) --🔥 Firewall rules, NAT, FortiGate, MikroTik, pfSense --📲 Local & remote access systems with QR-based tools ✅ Automation & Integrations - [login to view URL] / Integromat: custom automations for publishing, scraping, email, CRMs - WordPress auto-posting with SEO/ChatGPT - File servers & remote tools 💼 Recent Work Includes: - Full datacenter migration: planned and executed seamless transition of infrastructure across multiple servers - Production & development environment setup: for Odoo, WebUI, and Ollama (self-hosted) with isolated services and secure access - Self-hosted n8n automation: built custom workflows - Hosting & routing via Cloudflare Workers for clients using Vercel, React - Data pipelines combining scraping, automation
