I build AI systems that do real work: voice agents that answer and book, chatbots that qualify leads 24/7, automations that replace manual processes, and the AI content/personas behind modern brands. Recently I built a GoHighLevel round-robin lead router plus a live KPI dashboard for a sales team, cutting lead response from hours to under 2 minutes and saving 15+ hours a week. I'm a solo AI engineer, so you work directly with the builder. I ship working systems in days, not weeks. Tell me your workflow and I'll show you exactly how to automate or build it.

Manual follow-ups, scattered client information, missed calls, and disconnected tools slow businesses down. I help service-based businesses build AI automation systems that save time, reduce repetitive work, and make daily operations run smoother. I specialize in AI automation, n8n workflows, AI agents, voice agents, API integrations, Google Workspace automation, CRM workflows, and Wix lead-generation systems. My focus is not just setting up tools — it is helping businesses create practical systems that capture leads, organize information, follow up faster, and improve the client experience. What I can help you build: ✅ AI client intake workflows that collect leads, organize details, and send follow-ups automatically ✅ n8n workflows that connect forms, Gmail, Google Sheets, Google Calendar, CRMs, and other business tools ✅ AI chatbots and AI agents that answer FAQs, qualify leads, route requests, and support customers ✅ Voice AI / AI receptionist workflows for appointment booking, missed-call follow-up, and client communication ✅ Google Workspace automation for Sheets, Docs, Drive, Gmail, Calendar, and internal admin processes ✅ Wix website support, landing pages, forms, SEO basics, and lead capture systems ✅ API and webhook integrations to connect tools that do not naturally work together Tools I work with or can support include n8n, Make com, Zapier, OpenAI/ChatGPT, Google Workspace, Google Sheets, Gmail, Google Calendar, Wix, Stripe, Airtable, CRM tools, Retell AI, Vapi AI, ElevenLabs, Twilio, and API/webhook-based integrations. My process is simple and business-focused. I first understand your workflow, identify where time is being lost, then design a practical automation plan. After that, I build, test, document, and refine the system so it is reliable, easy to understand, and useful for your business long term. I also bring strong administrative and operations experience, which means I understand the real problems behind messy workflows: missed follow-ups, duplicate data entry, unclear records, slow response times, disconnected platforms, and manual tasks that should not take hours every week. My Upwork profile has 100% Job Success, 5-star feedback, and experience completing client work with accuracy, clear communication, and fast turnaround. I am detail-oriented, responsive, and focused on building systems that are practical — not overcomplicated.
