LangChain AI & RAG Developer | Legal Document Intelligence Agent
Are you looking to unlock the potential of your company's data with advanced Artificial Intelligence? I am a specialist AI & RAG Developer, and I build state-of-the-art Retrieval-Augmented Generation (RAG) systems that don’t just summarize—they deliver actionable intelligence from complex, proprietary data.
My Core Expertise Includes:
Custom RAG Application Development: I engineer high-performance RAG architectures that connect your internal documents directly to leading Large Language Models (LLMs) for accurate, contextual, and hallucination-free output.
Vector Database Engineering: From strategy to deployment, I am an expert in creating efficient Document Indexing & Embeddings and implementing scalable Vector Search solutions.
LangChain Ecosystem Mastery: I specialize in the full LangChain framework, leveraging its powerful features for LLM Orchestration, Chain Development, and building sophisticated Agentic Workflows.
Knowledge Graphs & Semantic Search: I don't just provide keyword matching; I build intelligent Knowledge Graph APIs and Semantic Search engines that understand the intent of a query.
Featured Project Spotlight: Advanced Legal RAG Agent
This showcase demonstrates my ability to handle highly complex and sensitive data. I developed an intelligent agent that parses and analyzes massive, complex legal case-law and statute databases.
Complex Multi-Source RAG: Integration of heterogeneous legal document types (Case-law, Statutes, etc.).
Semantic Search & Knowledge Graph: Advanced query understanding for precise legal research.
Tech Stack: LangChain, Qdrant Vector Database, OpenAI LLMs, Python, FastAPI.
If you are ready to move from AI experimentation to building production-ready AI applications that deliver a real competitive advantage, let's connect. I can help you architect a solution using the most efficient tools for your specific domain, from RAG & Agentic Apps to robust Semantic Search engines.

This is The Signal Room, my Zo Computer Challenge submission, live at zo.contrabob.pro.
I built it in Zo Computer as an AI-native personal website that acts like a founder and security command center instead of a static portfolio.
Visitors enter a SOC-style room, called SIGNAL ROOM, generate a custom clearance badge, unlock the system through a hidden 1337 console easter egg, and run a Signal Scan on their company or idea.
The result is an AI-powered Signal Brief with a Signal Score, positioning diagnosis, trust gap, revenue wedge, security risk, and fastest MVP move. It also includes avatar interaction, Stripe-ready Signal Audit monetization, Telegram lead logic, API-ready website analysis, gamification, sharing, and demo mode.
The web application is using real API services for security screenings and high-level security audits, so please use it responsibly.
The goal was to show what a personal website becomes on Zo Computer: a live operator system.
Video with the walktrough as per submission requirements is in the web application itself.

This is a web app with mobile app files ready to push to the app store if desired. Here is the app link with the temporary domain attached for review: https://marketplace-template-builde-47.created.app/
You can create a completely free account and use the app yourself, as it is connected to a backend database within Anything that stores user profiles for continued functional use.
Here are my socials to follow along:
ooh the mood forecasts are such a cool concept!
