Claude Code Agent Engineer | MCP Servers, HubSpot & Shopify Automation

The vibe coding era makes it easy to generate a prototype, but it often leaves you with a black box that nobody knows how to maintain. I specialize in bridging that exact gap taking fragile AI generated codebases and converting them into stable, production ready systems. Still doing work by hand that Claude could be doing inside the tools you already pay for? Shopify, HubSpot, GoHighLevel, your CRM, or your inbox. I build Claude agents that run real business processes, connecting them directly to your systems so they take active, verifiable work off your plate. 𝗪𝗛𝗔𝗧 𝗗𝗢 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗙𝗢𝗥 𝗬𝗢𝗨𝗥 𝗕𝗨𝗦𝗜𝗡𝗘𝗦𝗦? 1. CLAUDE AGENT TEAMS & MULTI AGENT WORKFLOWS Instead of relying on a single prompt to handle everything poorly, I build specialized agent teams that pass tasks seamlessly to one another. One researches, one validates, one drafts, and one executes. Built with human approval steps on consequential actions, your business process stays accurate, predictable, and fully under your control. 2. CUSTOM MCP SERVERS (MODEL CONTEXT PROTOCOL) Without an MCP server, Claude can only give you suggestions. With a custom MCP server, Claude can actively read and write across Shopify, HubSpot, Airtable, Supabase, and your internal APIs. I build secure MCP bridges so Claude can update inventory, score and route leads, process tickets, and manage records directly inside your stack. 3. CLAUDE CODE & WORKSPACE INFRASTRUCTURE I set up enterprise grade Claude Code and Claude Cowork environments using custom CLAUDE.md architecture, subagents, custom hooks, and slash commands. This keeps AI models strictly on rails inside your actual codebase, preventing logic drift and maintaining project context across long dev cycles. 4. VIBE CODE HARDENING & SAAS RESCUE When your prototype reaches 80% completion but breaks every time you add a feature, I step in as the adult in the room. I clean up spaghetti component structures, resolve state sync issues, secure loose Supabase RLS policies, and optimize API calls to prevent cloud bill spikes. 𝗠𝗔𝗞𝗜𝗡𝗚 𝗜𝗧 𝗣𝗥𝗢𝗗𝗨𝗖𝗧𝗜𝗢𝗡 𝗥𝗘𝗟𝗜𝗔𝗕𝗟𝗘 Most AI automations stop working the moment an unexpected API payload arrives. I engineer robust error handling, retry logic, rate limiting middleware, and Sentry logging into every build. You get a system that operates reliably even when nobody is actively watching it. 𝗦𝗢𝗠𝗘 𝗤𝗨𝗘𝗦𝗧𝗜𝗢𝗡𝗦 𝗖𝗟𝗜𝗘𝗡𝗧𝗦 𝗔𝗦𝗞 𝗠𝗘 1. What is an MCP server and why do I need one? It is the bridge between Claude and your tools. Without it, Claude gives advice; with it, Claude performs actions inside Shopify, HubSpot, or your database. 2. Will the AI make unauthorized changes or hallucinate? No. Consequential actions (like issuing refunds or sending external communications) are governed by strict deterministic rules and human approval gates. 3. Will I understand how to maintain this after you leave? Yes. Every project includes a Full Technical Handoff Report detailing architectural changes, logic decisions, and a clear maintenance roadmap.
