Hello Techies!
🚨 New Video Alert 🚨

If you’re a software engineer wondering
“If AI can already write code, what are companies actually hiring for now?”
this video is for you.

In this video, I break down how software engineering hiring is changing in 2026 — and more importantly, how to prepare without panicking.

Hiring isn’t broken.
It’s just measuring real engineering skills now:
system design, debugging, production thinking, communication, and AI fluency with judgment.

Hello Techies!

🚀 New Video is Live!

Have you ever wondered how Instagram loads your feed instantly—
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.

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

Hello Techies!

🚀 New Video Alert!

How do large-scale systems generate unique IDs without collisions?

In this video, I break down 5 real-world ID generation strategies used in distributed systems:

Auto-increment DB IDs

UUID / GUID

Snowflake-style time-based IDs

Zookeeper / etcd distributed counters

Hybrid ID generators (used by Instagram, Firebase, fintech systems)

If you’re preparing for system design interviews or building high-scale backend systems, this one is a must-watch.

Hello Techies!

🚨 New Video Alert! 🚨
If you’re building or learning distributed systems, you must understand why system clocks can’t be trusted — even with NTP or Chrony syncing them.

⏱️ In my latest video, I break down:
• Why timestamps go wrong across machines
• How tiny millisecond skews break ordering
• Logical clocks (Lamport, Vector) explained simply
• Java + Python demos you can try yourself
• Practical tips to fix misordered logs and event flow

If you’ve ever wondered “Why did this event happen before that one… according to the logs?” — this video is for you.

Hello Techies!

🚀 New Video Just Dropped!
Ever wondered how Cassandra distributes massive data across hundreds of nodes — without a master or bottleneck? 🤔

🎥 Watch now: How Cassandra Distributes Data (DHT + Hash Ring Explained)

In this video, I break down:
🔹 What a Distributed Hash Table (DHT) is
🔹 How consistent hashing prevents data reshuffling
🔹 How Cassandra uses vnodes and replication for perfect load balance
🔹 A short Java code demo to see it all in action 💻

If you’re learning System Design, Distributed Systems, or NoSQL databases, this one’s a must-watch!

💬 Tell me in the comments — which database concept should I explain next? (CAP Theorem, Gossip Protocol, or Replication Strategies?)
