Hire the Best Cloudflare Specialists

Most clients find me after wasting weeks on engineers who deploy fast but leave security gaps, brittle scripts, and zero documentation behind. Well, I do the opposite. I'm a DevSecOps engineer with 7+ years building cloud infrastructure that is production-hardened from day one, not secured as an afterthought. AWS, Kubernetes, CI/CD, secrets management, container security, GDPR-compliant workflows, all of it built clean and documented properly. I'm also one of the few engineers who builds AND secures AI agent systems. LangChain, CrewAI, RAG pipelines, MCP servers, I understand the attack surface of modern AI infrastructure that most security engineers have never touched. 🔐 Security & DevSecOps 🔹 Linux Hardening: firewalls, iptables, SSH lockdown, fail2ban, SSL/TLS 🔹 Secrets Management: HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, GCP Secret Manager 🔹 Container Security: Docker Hardening, Kubernetes RBAC, Network Policies, Pod Security Standards 🔹 Server Management: WHM, cPanel, Plesk, Webmin, Virtualmin 🔹 GDPR-ready Workflows: encrypted APIs, secure backups, access control 🔹 CI/CD Security: secrets scanning, signed images, GitHub Actions, GitLab CI, Jenkins ☁️ Cloud Infrastructure & DevOps 🔹 AWS, GCP, Azure, DigitalOcean: deployment, scaling, cost optimization 🔹 Infrastructure as Code: Terraform, Pulumi, Ansible 🔹 CI/CD pipelines: GitHub Actions, Jenkins, GitLab CI 🔹 Container orchestration: Docker, Kubernetes, Helm 🔹 GitOps: ArgoCD, Flux 🤖 AI Infrastructure & Automation 🔹 Multi-agent systems: LangChain, LangGraph, CrewAI, AutoGen 🔹 Model Context Protocol (MCP) server integration 🔹 RAG pipelines & vector search: Pinecone, Qdrant, Weaviate, ChromaDB 🔹 LLM app builders: Dify.ai, Flowise 🔹 Multi-model routing: OpenRouter 🔹 AI agents: Claude, ChatGPT, Gemini, Azure OpenAI, AWS Bedrock 🔹 Local LLMs: Ollama, Mistral, Llama on Linux servers 🔹 Workflow automation: n8n, Make, Zapier, APIs & webhooks 💻 Full Stack & WordPress 🔹 Backend: Laravel, Node.js, Java, NestJS, Python, Go 🔹 Databases: PostgreSQL, MySQL, MongoDB, Redis 🔹 WordPress: Elementor, Divi, Bricks, Oxygen, WP-CLI, Gutenberg, Headless WordPress 📊 Monitoring & Reliability 🔹 Observability: Prometheus, Grafana, OpenTelemetry, ELK Stack, Sentry, CloudWatch 🔹 Automated backups: Rclone, AWS S3, GCP buckets 💼 You're a great fit if you are: 🔹 A startup that needs infrastructure secured from day one 🔹 An agency that wants one reliable long-term technical partner 🔹 A business running AI agents that needs someone who understands both the build side and the security risks Tell me what you're building.

**Is your WordPress site hacked, broken, slow, or behaving unexpectedly?** I help businesses recover WordPress websites by identifying the root cause of the problem and implementing reliable, long-term solutions. I specialize in WordPress troubleshooting, malware removal, WooCommerce bug fixing, website recovery, migrations, and performance optimization. My focus is resolving the underlying cause of issues rather than applying temporary fixes. Many clients contact me when their website suddenly goes down, displays critical errors after updates, experiences WooCommerce checkout problems, becomes infected with malware, or suffers from unexpected performance issues. I investigate the root cause first, then implement solutions designed to keep the problem from returning. Clients usually hire me to: • Fix WordPress errors, bugs, and critical site issues • Remove malware from hacked WordPress websites • Identify and eliminate hidden backdoors or reinfection sources • Resolve plugin and theme conflicts • Fix WooCommerce checkout, payment, or cart issues • Restore access to WordPress admin or hosting problems • Investigate slow or unstable websites caused by plugin or database conflicts • Migrate WordPress websites between servers or hosting providers What I can help you with: • WordPress malware cleanup and security hardening • WordPress & WooCommerce bug fixing • Plugin troubleshooting and compatibility fixes • Performance optimization and speed improvements • Elementor debugging and layout issues • Hosting and server-related WordPress problems My approach: I focus on diagnosis first, fixes second. Before making changes, I review logs, plugin interactions, database behavior, and server responses to identify the real cause of the issue. This ensures solutions are stable and don't break again after the next update. Experience: I have worked on 400+ WordPress websites outside Upwork, covering malware recovery, complex troubleshooting, WooCommerce support, website migrations, performance optimization, and ongoing maintenance. This hands-on experience has enabled me to diagnose problems efficiently, identify their root causes, and implement reliable, long-term solutions instead of temporary fixes. Communication: Clients value clear communication and structured troubleshooting. I explain technical issues in simple terms, outline realistic solutions, and keep projects moving efficiently. If your WordPress site is hacked, broken, slow, or behaving unexpectedly, feel free to reach out. I’ll help diagnose the issue and recommend the safest way to fix it.

When something on your site, email, or infrastructure is broken or compromised and nobody can tell you why, that's the work I do. I'm a solo cybersecurity and web infrastructure consultant with 10+ years of hands-on experience...a forensic troubleshooter for web, email, DNS, ad-account, and access-control failures. Whether it's a hacked site, marketing or transactional email that won't reach the inbox, or systems behaving in ways nobody can explain, I trace problems back to their root cause rather than patching symptoms. Most of my clients are small business owners who've already tried the obvious fixes and need someone who can actually dig into the details. I work directly on the systems( WordPress, Shopify, WooCommerce, custom application stacks, and self-managed VPS environments on) rather than handing the work to a third party. That's a deliberate choice...I own the work end to end. Where I'm usually brought in: - WordPress malware removal and incident response — SocGholish/FakeUpdates, Magecart skimmers, SEO spam injection, card-testing and form-spam attacks - Email deliverability and authentication — SPF, DKIM, DMARC, MTA-STS, and inbox-placement diagnosis across Gmail, Microsoft 365, and others - Managed VPS hosting, migrations, and performance — Nginx, PHP-FPM, MariaDB, Redis, Cloudflare, CrowdSec, plus plugin audits, cache conflicts, and production-cutover validation - DNS configuration and forensics - Ad-account and access-control investigations — Google Ads/MCC compromise, click and lead fraud, tracking abuse, rogue or retained admin access, and OAuth/login review - Shopify and hosted-platform security — malicious redirects, third-party app and script review, blacklist and false-positive diagnosis Where it matters, I turn messy logs and partial evidence into a formal post-incident report you can hand to an insurer, agency, vendor, or counsel, so not just a fix but a defensible account of what happened and why. You'll get clear explanations written so you can actually follow them, documentation of what was done, what to watch for going forward, and anything else you'd want or need. I'd rather you walk away understanding your own systems than dependent on me.
