Senior DevOps & SRE | Troubleshooting | AI Systems & Python Automation

Reliability isn't accidental—it's engineered. When production environments crash, bottlenecks cripple your business, or you need to integrate cutting-edge AI pipelines into rock-solid infrastructure, I step in. With 10+ years of deep technical experience, I bridge the gap between Mission-Critical Troubleshooting, Modern Cloud/DevOps, and Applied AI Engineering. I don’t apply temporary band-aids; I diagnose root causes and architect self-healing, automated systems that prevent failures from ever repeating. --- ⚡ WHAT I DO BEST: 1️⃣ DEEP TROUBLESHOOTING & SRE (Mission-Critical Recovery) • Resolving "impossible" production incidents: 500/503 server crashes, high CPU/RAM bottlenecks, I/O latency. • Web server performance tuning: LiteSpeed, NGINX, Apache, CloudLinux, WHM/cPanel. • Complex network & routing diagnostics, DNS, CDN/Cloudflare Workers optimization. • Root-Cause Analysis (RCA) with detailed post-incident reports. 2️⃣ MODERN DEVOPS & CLOUD ARCHITECTURE • Cloud Infrastructure: Multi-cloud setups across AWS, Oracle Cloud (OCI), Hetzner, Alibaba Cloud. • Containerization & CI/CD: Docker, Docker Swarm/K8s, automated build & deployment pipelines. • Infrastructure as Code (IaC), Zero-Downtime database and server migrations. • Server Hardening, Security Audits, and automated backup/recovery strategies. 3️⃣ AI INTEGRATION & ADVANCED AUTOMATION • LLM & RAG Systems: Designing custom Enterprise RAG (Retrieval-Augmented Generation) pipelines and secure AI document analysis. • AI-Driven Workflows: Sentiment analysis, automated classification, and API-based AI model integrations. • Python Engineering: Custom automation bots, resilient ETL pipelines, and headless web scraping (Scrapy/Playwright). • Modern Backend & API Development: RESTful APIs, microservices integration, and system orchestration. --- ⭐ WHY CLIENTS TRUST ME: • 1,000+ Verified Upwork Hours with a 100% Track Record (Check my reviews below). • Client Mindset: I treat your infrastructure like my own—zero downtime, high security, and clear communication. • Clean Documentation: You receive well-documented architecture, ensuring you understand exactly how your systems run.
