AI Workflows & Marketing Automation | CRM, Email, Workflow Systems

🔧 Production Automation Systems — Not Demos, Not Slide Decks 🤖 Claude Code as a Daily Build Tool, Not a Buzzword Are you looking for someone who builds automation that actually survives contact with real operations? I engineer API-first systems, CRM architectures, and email marketing machines — and I ship them with Claude Code every day. Why Work With Me: ✅ API-First: My default is writing code against APIs. Make/Zapier only when they're genuinely the right tool — not the whole stack 📊 Full-Stack Builds: I handle strategy, architecture, copy, and design — you don't need three freelancers 🎯 Claude Code Native: Not a novelty. It's how I scope, build, test, and document every integration I ship 🔍 Detail-Oriented: Structured error handling, retry logic, dead letter queues, reconciliation checks — nothing silently drops 🚀 Async & Fast: Written communication only. Clear scope, clear timeline, documented deliverables Expertise & Services: 1️⃣ Claude Code Development: Every integration built through Claude Code — API endpoints, auth models, data mapping, error handling. What takes others days ships in hours, tested end to end 2️⃣ CRM Architecture: HubSpot, ActiveCampaign — custom properties, lifecycle stages, deal pipelines, workflow automation, contact deduplication, reporting. I know where every sync breaks before it breaks 3️⃣ Email & Lifecycle Marketing: Klaviyo specialist — flow architecture, trigger sequencing, segmentation logic, Shopify integration. Full audit-to-rebuild including copy and design 4️⃣ API Integrations: REST, OAuth 2.0, webhook signature verification, exponential backoff, batch processing, pagination handling. CRMs, form platforms, payment processors, marketing tools — if it has an API, I build against it 5️⃣ Tracking & Attribution: Meta CAPI, fbclid preservation across multi-platform funnels (Typeform → Calendly → CRM → Meta), UTM architecture, conversion event mapping 6️⃣ Course & Membership Platforms: Kajabi, Teachable — program structure, offer architecture, pricing strategy, checkout flows, community setup, drip content configuration 7️⃣ Workflow Automation: Make, Zapier, Airtable scripting — and knowing when to stop using them and write code instead 8️⃣ Shopify Integration: Klaviyo-Shopify flows, HubSpot-Shopify sync debugging, order/customer data pipelines, abandoned cart architecture Let's Work Together If you need automation that works on Monday morning — not just in the demo — I'm ready to start.
