I develop AI SaaS web applications, LLM-powered apps, and custom AI solutions using Next.js, React, Node.js, Python, LangChain, OpenAI API, and vector databases.
I help startups and businesses build scalable AI products, including AI chatbots, AI assistants, RAG applications, knowledge base systems, and SaaS platforms powered by large language models (LLMs).
Services I provide:
• AI SaaS application development
• LLM application development and integration
• OpenAI API integration and custom AI features
• AI chatbot and AI assistant development
• Retrieval-Augmented Generation (RAG) systems
• LangChain development and workflow automation
• Vector database integration with Pinecone and MongoDB Vector Search
• Full-stack web development with Next.js, Node.js, and Python
• SaaS Dashboards, authentication, subscriptions, and scalable architecture
Why choose me:
• Specialized in AI SaaS and LLM applications
• Build scalable, production-ready solutions
• Focus on performance, clean code, and UX
• Reliable communication and timely delivery
If you need an AI SaaS MVP, LLM application, chatbot, or custom AI feature, I can help transform your idea into a working product.

How I Work
Understand the business objective and technical constraints.
Design the architecture before implementation.
Build modular backend and AI workflows.
Test edge cases, reliability, and integration points.
Deploy, monitor, and document the system for maintainability.
My focus is not simply connecting an LLM API to an application. I help turn AI capabilities into software that can be integrated into real products and business workflows.
If you need an AI agent, RAG system, automation workflow, or AI-powered SaaS product and want someone who can contribute to both the architecture and implementation let's discuss what you're building.
