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.
Senior AI Engineer and SaaS Architect specializing in LLM integration (Qwen3, Llama3, GPT, Claude, Mistral) via Ollama, LangChain, LlamaIndex, and custom RAG pipelines. Creator of Gantto, AI Agent Skills, ExtractTheme Studio, and 43 shipped products across AI, security, SaaS, and developer tooling.
Currently co-founding multiple startups, translating deep technical expertise into product-focused execution.
