I’m a full stack AI developer who helps businesses build AI-powered products, integrate AI into their existing software, and automate the work that slows their teams down. I specialize in turning AI into working software. That includes custom AI products and SaaS features, AI integrations into existing apps and platforms, AI agents that reason and take action across your tools, workflow automations, voice agents for inbound and outbound calls, and GoHighLevel systems. Whether you’re launching a new AI product, adding AI to the platform you already have, or automating internal operations, I handle it from architecture to deployment. Why people work with me: I’ve helped scale a SaaS product to $200M ARR, so I build with real users, scale, and long-term growth in mind I’m one of the early builders in Voice AI and a Retell AI Certified developer I’m a Claude Certified Architect and a GHL Solutions Expert I build full stack, from front end and back end to APIs, integrations, and deployment, so you don’t need to hire multiple freelancers I’ve delivered production-ready AI systems for businesses in SaaS, real estate, healthcare, recruitment, and service-based industries How I work: First, I understand your product, your users, your current stack, and what you want AI to actually do. Then I build a working version quickly so you can test it with real data and give feedback. After that, I focus on reliability, edge cases, security, logging, and clean, maintainable code. As your product grows, I keep improving and scaling the system so it keeps up with your users.
