Senior Full-Stack Developer | AI Agents, n8n, Node.js, APIs, WordPress

I build AI agents, automations and integrations that take manual work off your team, with the care of a senior developer, not quick vibe coding. 10+ years of production development. Secure by design, with your data under your control. What I build: - AI agents and assistants: tools, memory and access to your real data, built on the OpenAI and Claude APIs, with MCP connections to your systems - Workflow automation with n8n: lead routing, order and invoice processing, reporting, content pipelines, with custom nodes and code steps when the standard ones are not enough - API integrations and custom backends in Node.js and PHP: payment providers, CRMs, stores, webhooks, sync jobs and internal tools - Deployment and hosting: n8n, Node.js services and agents on Railway, Docker or your own server, with Cloudflare, monitoring and backups - WordPress and WooCommerce: custom plugins, checkout and payment fixes, speed and Core Web Vitals, and connecting stores to AI agents through the new Abilities API and MCP Adapter - Fixing what is already there: legacy PHP and JavaScript, code written by AI tools that half works, slow or unstable production systems AI built like production software: - Your data stays under your control. Agents get only the access they need, through separate accounts and roles. Keys and passwords live in a secrets store, never in code or in prompts. - Nothing is sent to an AI provider unless the task needs it. I use API plans where your data is not used for training, and I can run n8n and other tools on your own server. - Agents cannot do anything risky on their own. Payments, deletions, emails to customers and other sensitive actions wait for a person to approve them, and every action is logged. - Every line of code, whether I or an AI tool wrote it, is reviewed by me, kept in Git, tested on staging and shipped with a way to roll back. - You get documentation, so your team understands the system and is not locked in to me. Before freelancing I spent four years building premium themes and plugins at CMSMasters, a top ThemeForest author. Since then most of my work has been on live production systems, where a careless change costs real money. I take one-time projects, audits and ongoing work. Tell me what you want to automate, connect or fix, and which tools you already use. I will reply with how I would approach it and the most practical first step.
