Still manually moving data between your CRM, Google Sheets, Airtable, Notion, HubSpot, Pipedrive, or some collection of tools that seemed like a good idea six months ago? Mate. How are you still holding up? At some point every growing business accidentally hires a full-time employee called "Copy & Paste". A lead comes in. | Someone updates the CRM. | Someone updates the spreadsheet. | Someone sends the email. | Someone books the meeting. | Someone copies the same data into another system. | Then an automation breaks. | Then someone fixes the automation. | Then another automation breaks because apparently software enjoys character development. The funny thing? • Most businesses don't have a people problem. • They have a workflow problem. That's where I help. I build AI Automation, AI Agents, AI Workflow Automation, Business Process Automation, AI Integration, Voice AI Systems, and SaaS Automation that remove repetitive work and allow teams to focus on work that humans are uniquely qualified to do. You know. | Thinking. | Making decisions. | Drinking coffee. | Anything except updating the same CRM record for the fifth time. My expertise includes: • AI Agent Development • Autonomous AI Agents • Agentic Workflows • AI Workflow Automation • AI-Powered Automation • AI Integration • AI Copilot Development • AI Customer Support • AI Appointment Setters • Lead Generation Automation • CRM Automation • Customer Support Automation • Sales Automation • Marketing Automation • Business Process Automation AI & LLM Development: • OpenAI API Integration • OpenAI Assistants API • ChatGPT Integration • Custom ChatGPT Development • Claude API • Gemini API • MCP (Model Context Protocol) • LLM Integration • LangChain • LangChain Development • LangGraph • RAG Systems • Retrieval-Augmented Generation (RAG) • Knowledge Base Chatbots • AI Chatbot Development • Custom Chatbot Development • Document Processing • OCR Automation • Lovable & Claude Code Voice AI & AI Calling Systems: • AI Voice Agents • AI Voice Agent Development • Voice AI • Conversational AI • AI Calling Agents • AI Phone Agents • AI Voice Receptionists • AI Lead Qualification • AI Customer Support • AI Appointment Setting Platforms: • Vapi • Retell AI • Bland AI • ElevenLabs • Twilio Integration • Or even custom platform if you want.... Workflow Automation Platforms: • n8n Expert • Self-Hosted n8n • n8n Workflow Development • Make or Integromat • Make Expert • Zapier Expert • Zapier Automation • Pipedream Development Business Systems & Integrations: • Airtable Expert • Google Sheets Automation • Notion Automation • HubSpot Integration • GoHighLevel Development • Pipedrive Automation • Monday CRM Development • Asana Automation • Slack Integration • Calendly Integration • WhatsApp Automation • WhatsApp AI Agents Backend & SaaS Development: Well, most automation freelancers stop once two apps are talking to each other. I usually start there because scaling and reliability joins the chat. The difficult part isn't connecting tools but making sure they keep working next month. And the month after that. And after somebody changes a field name at 2 AM and forgets to tell anyone. That's why I also build: • Backend Development • Full Stack Development • SaaS Development • AI SaaS Development • API Integration • Custom API Development • Webhook Integration • Third-Party Integrations • NestJS • Node.js • FastAPI • PostgreSQL • MongoDB • Golang • Microservices Systems I've built have automated thousands of repetitive operations, streamlined lead processing, reduced operational workload, improved customer response times, automated internal workflows, and supported revenue-generating business processes operating at scale. A few facts about me: • 49 Completed Jobs • 100% Job Success Score • Top Rated Developer • Microsoft Certified AI Engineer (AI-102) I work with startups, agencies, SaaS companies, and businesses across the US, UK, Europe, Australia, and the Middle East. Available across EST, CST, PST, GMT, and other overlapping time zones. Flexible with project-based work, ongoing engagements, part-time support, long-term contracts, and dedicated development work. So if you're currently spending your weekdays or maybe weekends manually updating CRMs, moving data between tools, fixing broken automations, chasing leads, or wondering why your "fully automated system" requires three people to keep it alive... Mate. It's time we had a little chit-chat.
