You will get I will build a custom RAG chatbot over your documents with LangChain
Project details
Need a RAG chatbot or AI system built with LangChain, connected to your own data? I build production ready AI systems, not demos.
What I Offer:
Custom RAG Development: RAG pipelines using LangChain and OpenAI, built on real production experience (I shipped one live with 300+ paying users)
Vector Search Integration: Semantic search across your documents using pgvector, tuned for relevance and speed
Full-Stack Delivery: API and app integration using FastAPI, Next.js, or React Native, whatever fits your existing setup
Clear Documentation: Setup, usage, and handoff docs so your team can maintain it after delivery
I've built this exact kind of system before at scale, RAG search across 12,000+ items, plus enterprise search tooling used by 50+ law firms in a past role.
Ready to get started? Send me your project details and I'll tell you honestly what's realistic for your timeline and budget.

About Canberk
AI Search Engineer | RAG, LangChain, pgvector | Shipped to Paying User
Berkeley, United States - 2:52 pm local time
Most retrieval projects demo beautifully and degrade quietly once the corpus grows. I know because I hit it. Building semantic search across 12,000+ documents, pure vector search kept missing exact-phrase queries users actually typed. I ended up combining pgvector cosine similarity with trigram text matching, and the hybrid approach fixed relevance in a way neither did alone.
That system is live in ActorRise, an AI platform I built and shipped solo. 300+ users, paying subscribers, running on a production ETL pipeline that handles scraping, content analysis, and batch embedding generation. Next.js and FastAPI on Supabase.
Before going independent I spent three years at Prevail Legal AI, where search accuracy was a compliance issue, not a nice-to-have. I built transcript search that let attorneys navigate 10,000+ line documents 3x faster, used across 50+ enterprise law firms.
What I can help with:
RAG pipelines: ingestion, chunking strategy, embeddings, hybrid retrieval
AI agents and chatbots: LangChain, LangGraph, OpenAI, Claude
Fixing RAG that already exists but returns bad answers
Full-stack around it: FastAPI, Next.js, React, Postgres, Supabase
I've taken two products from empty repo to paying users. If your project fits, send me the brief and I'll tell you honestly whether I'm the right fit.
