I help small businesses turn messy manual work into AI-powered workflows, chatbots, dashboards, and web systems that actually get used. I build practical systems with tools like OpenAI, Claude, GoHighLevel, Google Workspace, MailerLite, Supabase, Vercel, and custom web apps. My focus is simple: understand the workflow, build the first working version, test it, document it, and make it easy for you to use after I am done. Recent work I have built: - AI newsletter and content workflow for ACC Network using MailerLite, Supabase, Vercel, and Google Docs - Marketing Agent OS for routing content, campaign, research, and growth tasks - Local Glow Up, a small business web and lead capture system - AI News Bot deployed with Python, Docker, Discord, and VPS hosting - Prep2Eat, an AI-assisted recipe and mobile app workflow Best fit projects: - AI chatbots for websites or internal teams - GoHighLevel chatbot and workflow setup - Claude/OpenAI workflow automation - Google Sheets, Google Drive, CRM, and email integrations - Small business dashboards and operating systems - Lead capture, follow-up, and appointment workflow automation I am strongest when you have a real business process that needs to be cleaned up, automated, and explained clearly. I will not just drop a black-box AI setup on you. I will build it, test it, and leave you with simple notes so you understand how it works.
