Joseph A. | AI Automation Specialist Make com | n8n | GoHighLevel | Zapier | AI Agents | Claude Code | OpenAI I got into automation because I kept seeing the same problem: businesses were spending hours doing work that a good workflow could handle in the background. A lead would come through a form, someone would copy it into a CRM, another person would send the follow-up email, and someone else would remember to update the pipeline. Nothing was necessarily difficult, but there were too many small steps and small steps are where things get missed. That’s the kind of problem I like solving. I help businesses turn manual processes into AI-powered automation systems using Make com, n8n, GoHighLevel, Zapier, OpenAI, Claude, and Claude Code. I don't believe automation should simply be about connecting two apps. I first look at how the business actually works, find the bottlenecks, and then build a workflow around the outcome you want. What I Work With Make com & n8n Complex workflow automation Multi-step scenarios Routers, filters, iterators and aggregators Webhooks and HTTP requests API integrations Error handling and troubleshooting Data processing and synchronization Workflow optimization GoHighLevel (GHL) CRM setup and automation Lead capture and routing Pipeline automation Email and SMS follow-up Appointment workflows AI lead qualification Client onboarding GHL SaaS setup Snapshots and sub-account automation AI & AI Agents OpenAI / ChatGPT integrations Claude API Claude Code AI agents AI lead qualification AI customer support AI document processing AI data extraction AI-powered decision workflows Automated personalized responses Zapier & Integrations Zapier workflows REST APIs Webhooks JSON OAuth and API authentication CRM integrations Google Sheets Airtable Gmail Slack WhatsApp Third-party SaaS integrations A Typical Project For example, imagine a company receives 100+ leads every week. Instead of someone manually checking forms, copying information into GHL, deciding which leads are important, sending emails, and remembering to follow up, I can build a system where: Lead comes in → AI reads it → lead is qualified → GHL is updated → personalized message is sent → sales team is notified → follow-ups happen automatically. If something goes wrong, the workflow can flag the problem instead of silently failing. That's the difference I try to bring to every automation I build: less manual work, fewer missed steps, and a system the business can actually rely on. Beyond Automation I'm also comfortable working with APIs, JavaScript, databases, webhooks, JSON, AI/LLM APIs, system integrations, and troubleshooting. So when a native integration isn't enough, I can work with the API or build a custom solution around it. Whether you need a single Make com automation, a complete GHL CRM system, an n8n AI agent, a Zapier workflow, or a connected AI automation ecosystem, I can help design and build it from start to finish.

Growth shouldn't require more people. Reliable Automation powered by Claude, AI Agent Development, and n8n eliminates repetitive work, reduces operational costs, and gives your business the Automation it needs to scale with confidence. Manual work, disconnected systems, and unreliable Automation quietly reduce productivity, increase costs, and slow growth. Whether you're dealing with broken API Integration, rising Claude API costs, repetitive processes, or unreliable CRM Automation, the challenge is rarely Artificial Intelligence. The challenge is building Automation that works consistently in production. If any of these challenges sound familiar, your business is ready for better Automation. • Hours spent moving data between systems because API Integration isn't reliable. • CRM Automation that creates duplicate records or misses critical updates. • Marketing Automation and Email Automation that stop after a token expires or an API changes. • Claude workflows that work in testing but fail in production. • Rising Claude API and OpenAI API costs caused by inefficient AI Agent Development. • Teams spending more time fixing Automation than benefiting from Automation. • Workflow Automation that breaks as your business grows. • Lead Management Automation that fails to update your CRM or route new opportunities. • Lead Generation that still depends on manual work instead of intelligent Automation. Reliable Automation should eliminate these problems, not create new ones. Production-ready AI Agent Development transforms Claude into a reliable business system instead of another chatbot. Claude should automate repetitive work, execute business processes, support decision making, and connect every critical application through secure API Integration. Every AI Agent Development project should strengthen Automation, improve Workflow Automation, and reduce operational costs instead of creating more complexity. Reliable Automation connects Claude, n8n, Make com, Python, API Integration, Zapier, Airtable, and HighLevel into one connected ecosystem. Whether your business needs CRM Automation, Marketing Automation, Email Automation, Lead Management Automation, or Workflow Automation, every Automated Workflow should reduce manual work, improve Lead Generation, and continue creating value as your business grows. Artificial Intelligence delivers measurable results when Automation is built around business outcomes instead of demonstrations. Claude, OpenAI API, Python, API Integration, AI Agent Development, n8n, and Make com work together to build Automation that scales, improves CRM Automation, supports Marketing Automation, strengthens Email Automation, and keeps every Workflow Automation reliable. The outcome is simple. • Less manual work. • Lower operating costs. • Reliable Automation that scales with your business. • Smarter AI Agent Development powered by Claude. • Secure API Integration connecting every business system. • Production-ready n8n, Make com, Zapier, Airtable, and HighLevel workflows. • Better CRM Automation, Marketing Automation, Email Automation, Lead Management Automation, and Lead Generation. SEO PURPOSE If your business has outgrown manual processes and unreliable Automation, it's time to build Automation that continues creating value. Claude, AI Agent Development, n8n, API Integration, Make com, Python, Artificial Intelligence, CRM Automation, Workflow Automation, and Marketing Automation should help your business grow while your team spends less time managing repetitive work.

My job is not just to build your software; it is to eliminate your technical debt, establish market validation, and create an intuitive, scalable SaaS platform that your customers will love.

By partnering with a dedicated Bubble developer, you bypass months of structural overhead. Together, we use Bubble no-code architecture to build features at 10x the speed of standard development, allowing you to iterate on user feedback in real-time.

I construct fully functional MVPs designed to solve your user's primary pain point, allowing you to hit the market immediately and start generating feedback data.

I design bulletproof database structures, optimize workflows to keep your app running fast, and implement clean security policies to protect your proprietary user data. Custom Bubble API & Integrations: Your app should not live on an island. I construct seamless Bubble API connections to sync your platform with Stripe, OpenAI, HubSpot, Zapier, SendGrid, and any external service required to make your product operate smoothly. THE VALUE-FIRST DEVELOPMENT PROCESS When you hire me, you are getting an organized, repeatable framework engineered for product success: ✅ Architecture & Database Design: Before a single element is placed, we structure your database for speed, logic, and long-term scalability. ✅ UI/UX Prototyping: Your users expect a clean, professional, and responsive design that functions perfectly across desktop, tablet, and mobile devices. ✅ Core Feature Engineering: We construct the critical mechanics of your app, including user authentication, subscription paywalls, and proprietary dashboards. ✅ Testing & Optimization: I run comprehensive edge-case testing and optimize workflow speeds to guarantee your application remains lightning-fast under heavy load. ✅ Seamless Hand-off: You retain complete ownership of your intellectual property, supported by clear Loom video walkthroughs so you never feel locked out of your own product. TECHNICAL STACK & ECOSYSTEM EXPERTISE To maximize search relevance and ensure Upwork's algorithm indexes this profile under every major search scenario, here is the technical ecosystem I bring to your project: ✅ Platforms & IDEs: Bubble io, Bubble No-Code, Custom Plugins ✅ SaaS Crucial Features: Stripe Subscription Billing, User Onboarding, Multi-Tenant Dashboards, Automated Email Sequences ✅ Bubble API Integrations: REST APIs, Webhooks, JSON Payloads, OAuth 2.0, OpenAI GPT-4, Google Calendar, SendGrid, Zapier, Make ✅ Performance Engineering: Bubble Database Optimization, Workflow Speed Maximization, Single Page App (SPA) Architecture, Responsive Layouts.

Still copy-pasting data between apps like it's 2009? That's not bad luck it's a broken workflow quietly costing you leads, time, and sanity. Every missed follow-up, every duplicate contact, every "wait, did anyone handle this?" moment traces back to gaps between your tools. I'm a Zapier automation specialist. I close those gaps. Messy onboarding? I turn your five-email, six-tab process into one trigger client signs up, everything else runs itself. No more "did I forget a step." Leads going cold in your CRM? I connect your lead sources with automated tagging, routing, and follow-ups so hot leads get touched while they're hot, not three days later. Forgetting to invoice people? I automate billing, payment tracking, and reminders so cash flow stops depending on your memory. Team finding out too late? I set up real-time notifications and cross-app syncing so the right person knows the second something happens. I work with Zapier, Makecom, Airtable, HubSpot, Pipedrive, and GoHighLevel connecting what you already use, not replacing it. Everything I build is documented in plain English and tested until it's boring and reliable, because an automation nobody understands is just a time bomb. You already know which problem is yours, you felt it reading this. So don't overthink it. MESSAGE ME, tell me what's driving you crazy in your workflow, and I'll tell you straight whether it's a quick fix or a bigger build. No pitch, just an honest answer.
