About this gig
I will develop custom AI solutions tailored to your business needs, including AI chatbots, AI agents, automation systems, and full-stack AI applications. With 10+ years of full-stack engineering experience and strong expertise in modern AI technologies, I build scalable, production-ready systems that integrate AI directly into real business workflows.
I can help you build:
- AI chatbots with custom knowledge bases
- Retrieval-Augmented Generation (RAG) systems
- AI agents and automation workflows
- GPT / LLM-powered web applications
- AI SaaS MVP platforms
- Document analysis and AI data processing tools
- AI API integrations (OpenAI, Claude, etc.)
Technologies I commonly use include Python, Node.js, React, Next.js, LangChain, vector databases, and cloud platforms such as AWS, GCP, and Azure.
My focus is not just building demos, but delivering reliable, scalable AI systems that can support real products and business growth.
