I'm a Full-Stack Software Engineer with 6+ years of experience building SaaS applications, custom web platforms, and high-converting sales funnels. I've built 500+ websites across 70+ industries and contributed to a $10M-funded HealthTech startup featured in Bloomberg, TechCrunch, and The Wall Street Journal.
Today I specialize in GoHighLevel funnels, CRM setup, automation, and landing pages that help businesses generate more leads and book more appointments. Unlike template-only freelancers, I build custom solutions whenever your project requires more than drag-and-drop.
