Project details
🚀 Production-Ready RAG Pipeline Development
I build end-to-end Retrieval-Augmented Generation (RAG) pipelines that connect your documents and knowledge bases to powerful LLMs like GPT-4 and Claude.
✅ What's Included:
• Document ingestion (PDFs, Word docs, URLs, databases)
• Vector embedding with OpenAI or open-source models
• Vector database setup (Pinecone, ChromaDB, Weaviate, FAISS)
• Semantic search with chunking & re-ranking
• LLM integration (GPT-4, Claude, Llama)
• REST API endpoint for your application
• Chat UI (optional)
• Source citation in responses
🛠 Tech Stack:
LangChain / LlamaIndex • Pinecone / ChromaDB • GPT-4 / Claude • FastAPI • Python
📦 Packages:
• Basic: Single doc type RAG, 3 days — $299
• Standard: Multi-doc + chat UI + re-ranking, 7 days — $599
• Enterprise: Multi-source + fine-tuning + cloud deploy, 14 days — $999

Hermes Agent setup and new briefing task
Working with Ravi was an outstanding experience from start to finish. He brings deep expertise in AI agents and AI-powered web applications, and that knowledge was immediately apparent in how he approached our project. He helped me build a Hermes agent and demonstrated a clear understanding of both the technical architecture and the real-world problem we were trying to solve, which made the entire process efficient and collaborative.
What sets Ravi apart is his combination of technical skill and communication. He was consistently responsive, asked the right questions upfront, and kept me informed at every stage. He understood the scope of what we were building and delivered with precision and care.
If you are looking for a developer who can take a complex AI concept and turn it into a working, well-built solution, Ravi is the right person. He is the kind of collaborator you want on technically demanding work, and I would hire him again without hesitation. Highly recommended.

I build AI systems that RUN OPERATIONS — not just answer questions.
▪️ RAG pipelines that cut support tickets by 40%
▪️ AI agents that qualify leads, make outbound calls & book appointments 24/7
▪️ Multi-agent workflows that replaced 3 full-time coordinators for a property firm
▪️ Automations that save clients 10–20 hours every week
All running in production, without human intervention. That's the gap between a demo and a deployed system — and that's where I work.
🎁 NOT SURE AI FITS YOUR WORKFLOW? I'll build you a free mini-POC — something small and real you can test on your own use case before committing a dollar.

⚙️ HOW I WORK
1. Scoping call → understand your problem
2. Architecture → design the right system
3. Fast prototype → working demo in days
4. Production hardening → scale, security, monitoring
5. Documentation & handoff → your team owns it
💬 SEND ME YOUR IDEA — even rough notes. I'll give you an honest take: how I'd build it, what it realistically takes, and whether AI is even the right call (sometimes it's overkill — I'll tell you straight). If it's a fit, I'll show you a working mini-POC before you commit a dollar. Let's build something that actually runs.
