About Brendan

🛠️ EXPERT WEB & INFRASTRUCTURE: I FIX, SECURE, AND ACCELERATE YOUR WEBSITES


You have a WordPress project or a complex web infrastructure causing you trouble? Are you looking for an expert who can get their hands dirty (Nginx, SSL, Backend) to stabilize and optimize your platforms?

Independent developer with 8 years of experience, I am your "Anti-Bloat" partner. I don't install useless plugins: I optimize code, server, and architecture for measurable results.

🛡️ CURATIVE MAINTENANCE & RESCUE
  • Complex Debugging: Resolving PHP conflicts, server errors, and WooCommerce plugin bugs.
  • Cleaning & Security: Disinfecting hacked sites, hardening security, and implementing firewalls.
  • Agency Support: Are you an agency and your clients have technical emergencies? I step in as reinforcement, with full transparency and architectural rigor.

⚙️ INFRASTRUCTURE & SYSTEM (Ops)
  • Server Setup: Linux administration, Nginx/Apache configuration, SSL/TLS certificate management.
  • High-Performance Environments: Server performance optimization (Redis, advanced caching, Docker).
  • Migrations: Complex data transfers without service interruption and without SEO loss.

⚡ "ZERO-BLOAT" PERFORMANCE
  • Technical Audit: In-depth analysis of LCP, Core Web Vitals, and bottlenecks.
  • Radical Optimization: Redesigning heavy themes for a light and ultra-fast "Vanilla" approach.
  • Robust Backend: Developing custom scripts and API integrations to replace complex systems.

🤖 AUTOMATION (n8n & AI)
  • Business Workflows: Automating your processes (CRM, logs, data) to eliminate repetitive tasks.
  • AI Agents: Integrating AI solutions into your workflows to increase productivity.
