About me
I am a Senior AI Architect & Full-Stack Engineer. With a decade-long Top-Rated reputation on Fiverr, I apply an obsessive attention to detail to engineer high-performance AI & scalable SaaS products.
What I build:
🧠 Local AI Engines (C++): Zero API costs, 100% private (Ollama).
⚙️ Multi-Agent Systems & RAG: AI that reasons, remembers, and doesn't hallucinate.
🚀 Full-Stack SaaS: Node.js, React, TypeScript.
I don't build simple wrappers; I architect enterprise solutions that cut costs and scale. Send me a message!
