# Speaking at PyCon India 2025: “RAGs to Riches – Efficient Web Chatbot with Async Scraping & Hybrid Re-Ranking”

I am excited to share that I will be speaking at **PyCon India 2025 in Bangalore** on a topic that is very close to my current work in applied Generative AI:

**RAGs to Riches: Efficient Web Chatbot with Async Scraping & Hybrid Re-Ranking**

This session focuses on building **production-grade Retrieval-Augmented Generation (RAG) systems** that move beyond demos and actually scale.

### What the talk is about

The talk walks through how to:

* build a web chatbot powered by **RAG architecture**
    
* perform **asynchronous web scraping** to keep knowledge fresh
    
* use **hybrid re-ranking** (semantic + keyword + metadata signals)
    
* optimize **latency, recall, and cost**
    
* avoid common pitfalls like hallucinations and noisy retrieval
    

Attendees will see how asynchronous pipelines dramatically improve ingestion throughput and how retrieval quality depends far more on **chunking, indexing, and ranking strategies** than just “which LLM is used.”

### Who this talk is for

* Python developers
    
* data and ML engineers
    
* architects deploying LLM systems
    
* anyone moving from prototype to real-world AI workloads
    

You will gain practical patterns for deploying **web-scale chatbots** backed by modern Python async capabilities and hybrid search techniques.

### Why this matters

As LLM adoption accelerates, the real differentiator is not model selection but **how intelligently you retrieve and rank information**. This talk emphasizes:

* high-quality data pipelines
    
* efficient Python async design
    
* evaluation techniques for RAG quality
    
* reliability, observability, and safety
    

### Closing note

PyCon India has always been a community I admire, and it is an honor to contribute to it in 2025. I am looking forward to connecting with developers, researchers, and practitioners who are building the next generation of AI systems.

If you are attending PyCon India 2025 in Bangalore, I would be happy to meet you there.
