You will get a custom AI-powered web application with LLM integration
Rising Talent
Project details
Get a modern, full-stack web application custom-built with seamless AI model integrations and custom dataset training.
Instead of building simple standalone bots, I engineer complete web applications that harness state-of-the-art AI models (OpenAI, Claude, Gemini). Whether you need custom fine-tuned LLMs on your proprietary data, semantic search, or automated AI workflows directly inside your web app, I deliver a scalable, production-ready product.
What’s Included:
• Custom Web Development: Responsive, high-performance web applications built with Next.js 15, React, TypeScript, and Tailwind CSS.
• AI Model Integration & Training: Fine-tuning LLMs on your custom datasets, RAG implementation, and embedding vector stores (Supabase/Pinecone).
• Backend Infrastructure: Production authentication, PostgreSQL databases, server actions, and API endpoints.
• Payment & User Management: Complete integration with Stripe for subscription management and customer dashboards.
Transform your vision into an intelligent, AI-native web product ready to scale.
