I build production-grade AI and SaaS systems with 20+ years of engineering experience. From LLM-powered RAG pipelines and autonomous agents to multi-tenant platforms, I ship things that work at scale — with clean architecture, real security, and zero fluff.
Creator of Gantto, AI Agent Skills, ExtractTheme Studio, and 30+ shipped products across AI, security, SaaS, and developer tooling.
Currently co-founding multiple startups, translating deep technical expertise into product-focused execution.
