About this gig

Want to build an AI Web Application powered by real RAG (Retrieval-Augmented Generation) and semantic vector searchnot just a basic wrapper?


Hi, Im Aditya, Founder & Lead Engineer at DORVANTECH. I engineer production-grade AI applications, custom RAG pipelines, and real-time LLM systems using Next.js 16, React 19, TypeScript, Python, Google Gemini, OpenAI, and Firebase GenKit.


What I Build:

* Custom RAG Pipelines (Chat with PDFs, Docs, SQL Databases, or custom data)

* Semantic Search & Matching Engines (Resume/Job/Product matchers using vector embeddings & cosine similarity)

* Full-Stack AI Web Apps with Auth, Prisma, PostgreSQL & PDF Export

* Real-time AI Interfaces & Automated LLM Workflows


Tech Stack: Next.js, React, Node.js, Python, PostgreSQL, Prisma, Supabase, LangChain, OpenAI/Gemini APIs, Vector Databases, and WebSockets.
