Chi sono
Hello! I'm Konstantin, a specialized Full-Stack Developer focused on building modern AI-powered SaaS applications and state-of-the-art embeddable web solutions.
My technical stack is built around React.js, Node.js, Express, and Prisma ORM. Beyond standard web development, my core expertise lies in AI integration: I build intelligent, embeddable B2B AI chat widgets for websites, implement RAG (Retrieval-Augmented Generation) knowledge base systems, and create complete SaaS platforms from scratch featuring secure authentication (OAuth, JWT), user dashboards, and Stripe billing.
