I'm building AI SaaS applications as a freelance AI Product Engineer, deploying autonomous workflows and smart assistants with OpenAI, Anthropic, Vercel AI SDK, LangGraph, RAG, and vector databases.

At Plus8Soft, I delivered frontend architectures for AI-powered web applications, fintech platforms, and a digital health portal with a 24/7 AI patient assistant and real-time scheduling used by 1,000+ active users.

Previously at Logix Software and AyoTech, I built scalable enterprise and e-commerce products with Next.js, React, TypeScript, and Node.js. I improved performance and SEO, achieving Lighthouse scores above 90 and reducing Time to Interactive by 45%.
