You hired a full stack developer. You got a web app. What if you also got AI features your competitors don't have yet? I'm a full stack developer with 7+ years of experience building full stack web apps and SaaS products, React frontend, Node.js backend, MongoDB database, clean APIs. The kind of developer who ships production-ready work, not prototypes. But here's what most full stack developers can't offer: I also build the AI layer. Not a ChatGPT wrapper slapped on at the end. Real AI features, integrated into your product's architecture, connected to your data, and built to actually work under real user load. Clients are asking for this more and more. Most developers make them hire someone else for it. I do both.
