Vedran J.
Cloudflare DDoS/Bots/Workers | AWS/Linux DevOps & AI Infrastructure
I fix urgent production problems: downtime, 500/502 errors, DNS/SSL failures, hacked WordPress sites, malware infections, Cloudflare misconfigurations, Magento/Shopify performance issues, failed migrations, server overload, and bot attacks. I start with a capped fixed-price diagnostic, so you know the root cause fast — without open-ended cost. ▸ EMERGENCY TROUBLESHOOTING — AWS/Linux, NGINX, PHP/MySQL, DNS, SSL, cPanel/Plesk. I diagnose across the full chain, stabilize live systems without breaking revenue paths, and explain the root cause in plain language. ▸ MALWARE REMOVAL & HACKED SITE RECOVERY — WordPress, Magento, and Linux server cleanup: webshells, backdoors, crypto miners, spam relays, SEO spam, redirect hacks. I find how they got in, remove everything (not just the visible files), fix the entry point, restore email/Google blacklist reputation, and harden so reinfection doesn't happen. ▸ CLOUDFLARE SECURITY & TRAFFIC ABUSE — WAF, DDoS mitigation, bot protection, rate limiting, Workers, Zero Trust. Scraping, carding, fake signups, login/cart/checkout abuse, API abuse. Cloudflare's defaults stop yesterday's attacks; I write the rules that stop yours. ▸ ECOMMERCE PROTECTION & CLEAN ANALYTICS — Shopify, Magento/OpenMage, WooCommerce. Bots inflating your sessions, wrecking your conversion rate, and feeding bad signals to Meta/Google? I block them at the edge — before they click your ads and pollute your pixels — and migrate analytics to Cloudflare Zaraz for clean attribution. ▸ AWS & DEVOPS — Architecture, EC2, VPC, CloudFront, RDS, ECS/Docker, migrations with zero downtime, monitoring, cost optimization, hardening. ▸ SECURE AI AGENT INFRASTRUCTURE — I deploy and harden agent, MCP, and automation workloads on AWS/Linux and cloud VPS environments. This includes Docker, reverse proxy, SSL, access controls, secrets, backups, monitoring, Cloudflare/API protection, and recovery documentation. I turn working prototypes into secure, operable production services. HOW I WORK: capped diagnostic first → root cause in plain language → fix with your approval → hardening so it doesn't happen again. I sign NDAs, ask only for the access I need, and document what changed. If production is on fire right now, send me the symptoms and URLs — I likely start today.
