πŸš€ Agentic AI Patterns Explained Simply for Software Engineers

AI is moving beyond simply answering questions.

Today, enterprises want AI that can reason, use tools, collaborate with other agents, and actually complete business processes.

In this new video, I explain the most important Agentic AI patterns with practical examples:

πŸ”Ή Prompt Chaining
πŸ”Ή Routing
πŸ”Ή Parallelization
πŸ”Ή Evaluator-Optimizer
πŸ”Ή Tool Use
πŸ”Ή Reflection
πŸ”Ή Multi-Agent Collaboration

I also explain when to use each pattern, how they work, and the trade-offs around cost, latency, reliability, and observability.

🎯 If you're a software engineer with 1–10 years of experience and want to understand how Agentic AI systems are architected, this video is for you.

πŸ‘‰ Watch the new video and let me know: Which Agentic AI pattern do you think will be most useful in real-world applications?

Hello Techies!

🚨 New Video Alert!

Most engineers get this wrong:

πŸ‘‰ Is Kafka Pub-Sub?
πŸ‘‰ Is RabbitMQ a Queue?
πŸ‘‰ What exactly is a Message Broker?

In this video, I break down the confusion between:

Message Queue vs Pub-Sub
Pattern vs Broker vs Product
And how systems actually work in production

If you're working with Kafka, RabbitMQ, or SQS, this will change how you think about system design.

🎯 By the end, you’ll stop asking:
β€œKafka or Queue?”
…and start asking the right question.

πŸ’¬ Curious β€” where have you used Queue vs Pub-Sub in your system?

🚨 New Video Alert!

Ever wasted 30 minutes searching Confluence or Slack for one answer?

In this video, I break down how RAG-based AI chatbots help companies unlock internal knowledge β€” without fine-tuning models or risking data exposure.

We cover:
βœ… Why public AI chatbots fail inside companies
βœ… How RAG prevents hallucinations
βœ… A real production architecture using Bedrock, OpenSearch & Titan
βœ… How this boosts engineering productivity

This is practical system design β€” not hype.

Have you ever wondered how Instagram loads your feed instantlyβ€”
even though it contains photos, videos, likes, comments, and ads
for hundreds of millions of users at the same time?

In this video, I break down how Instagram actually does it, using:

Precomputed feeds

Multi-layer caching

CDN-based media delivery

Pagination & lazy loading

Prefetching during idle time

Graceful degradation at peak traffic

This video is a real-world application of the concepts I explained earlier in my videos on Caching Strategies and How CDNs Work.

πŸ‘‰ If you’re preparing for system design interviews or want to understand how large-scale backend systems are built, this one is for you.
