Full-Stack AI Developer | AI Agents, Custom CRM & Business Automation

⭐️ Top Rated Plus AI Developer | $100K+ earned | 100% Job Success You work directly with me, not a rotating team of juniors. You get my full attention, fast and clear communication, and 15 years of business, automation, and engineering behind every call. I architect and build the custom software your business runs on, and I take only 2 or 3 clients at a time so yours gets real speed and quality. You end up with a production-ready system built for how your team actually works, and it scales as you grow. You leave our first call with a clear plan, and working software in weeks. ✅ What I build • Custom business apps and internal tools (CRM, accounting, ops platforms) • AI agents and automation (reply agents, assistants with persistent memory, workflow systems) • Full-stack web apps (Next.js, React, Node, Python) • Dashboards, reporting, and data visualization • API and third-party integrations (CRMs, payments, email, Slack) • RAG and AI built into your existing product 📈 Recent work • Self-service scheduling for a US healthcare company that saves about 700 hours a month • A bookkeeping bot that runs 99% of the books on its own • A team CRM handling 20 brands, 50 projects, and 200+ tasks a month • An AI reply agent handling around 100 replies a day, 80% without a human On top of that, I ran e-commerce businesses for over 15 years, so I have a strong understanding of marketing ops, media buying, and email marketing on Klaviyo. I ship software that takes manual work off your team and keeps paying for itself. I do my best work as a long-term partner on bigger builds, not one-off gigs. Tell me the problem you are trying to solve and I will tell you exactly how I would build it. Juan
