About Me

With over a decade of experience, I've built a reputation for delivering high-quality full-stack solutions. My journey began in 2009, and since then, I've worked with clients worldwide through platforms like Upwork, maintaining a perfect 5-star rating.

I specialize in building modern web applications with React, Next.js, and Node.js. From responsive frontends to scalable backends, I handle the full development lifecycle. My experience spans various domains including automation tools, productivity applications, and complex business integrations.

For AI development, I leverage JavaScript and TypeScript exclusively to build intelligent solutions with OpenAI, LangChain.js, and modern AI tools. No Python needed - just deep expertise in the JavaScript ecosystem to create powerful, scalable AI applications.
