Project details
You will get a custom vector search and semantic search system that helps users find the right information based on meaning, not just exact keywords. I can help you add AI-powered search to your app, website, SaaS platform, documents, product data, or knowledge base.
I will set up embeddings, vector search, backend APIs, indexing, and search logic based on your data and business needs.
This project is ideal for document search, knowledge base search, product search, internal tools, AI assistants, and SaaS platforms that need smarter and more accurate search results.
I have experience building AI assistants, RAG systems, backend APIs, SaaS platforms, and real AI products like TubeGenius, FireVideos, LayerK Agent, and Geviti.
The final result will be clean, practical, and built to make your search experience faster, smarter, and more useful.

One of my key projects was "TubeGenius" an AI-powered SaaS platform for YouTube creators. I helped turn the client’s idea into a working product with AI script and title generation, a user-friendly web application and scalable backend functionality. The project grew into a $9,000+ engagement and received excellent client feedback.
More recently, I built and integrated a RAG system into an existing platform. The client highlighted the accuracy of the context retrieval and the seamless implementation.
