Job Success

If your team is buried in repetitive tasks, leads are slipping through the cracks, or you're stitching together tools that were never meant to connect, you're not alone. Real automation isn't about connecting apps. It's about building reliable, AI-powered systems that make your business run faster, smarter, and with less manual effort.
I design and build AI agent systems, CRM workflows, and automation pipelines using n8n, Claude (Claude API, Claude Code, Claude Agent SDK), OpenAI/ChatGPT, and MCP servers (Model Context Protocol), connecting your CRM, GoHighLevel, email, SMS, and business tools into one coordinated, self-running operation.
Recent project: I designed and implemented a custom business automation system in GoHighLevel that eliminated repetitive manual work end-to-end. The build automated lead capture, email and SMS follow-ups, appointment booking, and CRM pipeline updates using intelligent branching logic, plus marketing tool integrations, automated nurture sequences, and real-time reporting workflows. Result: a scalable system that cut manual work, increased engagement, and simplified day-to-day operations.
We may be a great fit if:
✔ Your team spends hours every week on repetitive administrative tasks
✔ Leads are falling through the cracks because your CRM, GoHighLevel, or funnel/pipeline isn't connected
✔ You want AI agents that actually operate your business processes — not just generate content
✔ Your business is growing, but your operations, calendar/appointment flow, or reporting aren't keeping up
✔ You need automation that's audited, tested, documented, and built to scale so your team can maintain it
Working with me, you'll:
Eliminate manual work with AI agents and automated workflows
Connect your business applications (CRM, GoHighLevel, email, SMS, calendars, APIs, webhooks) into one seamless system
Improve lead generation, nurturing, follow-up, and appointment-booking response times
Get funnels, pipelines, and landing pages that convert, not just automations that run
Reduce costly errors through intelligent, monitored automation with proper error handling and audit logging
Get an AI-powered web app, chatbot, or internal tool where a dashboard makes more sense than a workflow
Gain systems with documentation so your team isn't dependent on me forever
My expertise includes:
GoHighLevel automation, CRM workflows, funnel & pipeline builds, sub-account/snapshot setup
n8n workflow & business process automation
AI agent & multi-agent system development (Claude, ChatGPT/OpenAI, RAG, conversational AI)
Claude API, Claude Code & Claude Agent SDK integration
MCP (Model Context Protocol) server development & integration
API & webhook integrations (Zapier, Twilio/SMS, Stripe, and more)
Lead generation, nurturing, and follow-up automation
Python, JavaScript/TypeScript, React, Node.js development
Landing pages, WordPress, and Shopify builds
Technologies: GoHighLevel • n8n • Claude / Claude Code / Anthropic API • OpenAI/ChatGPT • MCP • REST APIs • Webhooks • Zapier • Twilio • Python • JavaScript/TypeScript/Node.js • React • CRM platforms • Google Workspace • WordPress • Shopify • Stripe
My approach: I don't build automation just because it's possible. Every project starts with understanding your business, mapping the actual bottleneck, and designing a workflow, agent, or CRM system that produces a measurable result, reliable, documented, and built to scale with you.
Whether you need a single GoHighLevel workflow, a Claude-powered AI agent, or a full AI-driven operations system, my goal is simple: build things that save time, cut errors, and let your business grow without adding headcount.
