I build custom AI applications that solve real business problems. Whether you need an AI chatbot, a RAG knowledge base, workflow automation, or a complete AI SaaS platform, I can help take your idea from concept to production. I have 12+ years of software development experience and have successfully delivered 125+ web applications and enterprise software projects.

Today, I combine that engineering experience with modern AI technologies to build intelligent applications that businesses can use every day. Most of my work goes beyond proof-of-concepts.
