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.
