Hi, I'm Josh 👋 — a Silicon Valley engineer turned obsessed automation geek. I built the UI for a multi-million dollar IoT initiative in San Francisco for Meta. I’ve also modernized legacy government systems used daily by thousands of VA employees. And I scaled my DTC brand to over $1M in sales—all powered by high-ROI automations. The nerdy deep dive (if you're into that sort of thing): I build automation systems that save time, drive revenue, and scale like hell. From replacing tedious manual workflows to launching AI-driven chatbots, my goal is simple: create smart systems that deliver real leverage. Here’s what that looks like: - AI Assistants & Chatbots: Custom logic flows, dynamic knowledge bases (auto-updating as your content evolves), and trained AI that handles everything—from lead capture and appointment setting to fully automated customer support. - Lead gen machines: Automatically source, qualify, and follow up via email, SMS, or DMs using custom-built AI icebreakers. Book meetings while you sleep. - Content automation systems: Turn a single idea into blogs, YouTube scripts, social posts, images, and metadata—the entire content ecosystem automated. - Automated client & team onboarding: Payments, briefs, internal docs, CRM updates, and SOP delivery—all triggered and managed hands-free. - API-powered integrations: I've integrated nearly every major CRM and project management platform—from Salesforce and HubSpot to Airtable, ClickUp, Trello, and beyond. With custom APIs, we can connect virtually anything. Whether you're ready to 10x a marketing channel, streamline your operations, or finally escape Google Sheets purgatory, I'll build a solution that works today—and effortlessly scales tomorrow. Let’s build something efficient—and maybe even a little unfair. Looking forward to working together!
