The setup is now handling 10x more traffic without breaking a sweat. Redis + Docker combo is seriously powerful when done right!
Anyone else struggled with this integration? What worked for you? 🤔

Just spent the day wrestling with Redis + Docker integration and finally got it working smoothly! 🎉
Here's what I learned the hard way:

Cache invalidation was a nightmare. Started with simple TTL but realized I needed smarter strategies. Now using cache-aside pattern- check cache first, then hit the database if needed. Also Memory management is crucial! Redis was eating up RAM until I set proper maxmemory policy

@redBus_in @redBus_in I have already DM’d my details right after your request, but there has been no response yet.

Please check your messages and update me on the refund status. It has already been over 7 days since the operator confirmed the refund.

This delay is highly inconvenient.

[Krishna Khattri @Khattri_27]

Hey @redBus_in,
My bus from Bhopal to Jaipur on 31st July was cancelled due to a strike. The operator confirmed they’ve already refunded the amount to redBus, but I haven’t received anything yet.
I’ve tried everything — still no resolution.

@redBus_in Please check your dm.

[Krishna Khattri @Khattri_27]

I trusted @redBus_in for smooth bookings, but this kind of support failure after a cancellation is unacceptable.

I want this resolved immediately — refund my money and fix your support system.

Your AI bot is stuck in a loop and keeps redirecting me to the same responses. There’s no human support, and I can’t raise a proper complaint.

In fact, now I can't even log in myself to that stupid helpbot.

It is an extremely frustrating experience for a simple refund.

📸 Used pre-signed S3 URLs to allow secure, direct-to-cloud image uploads.
The client’s team can upload dozens of images without stressing the server.
Smart storage wins.

🧠 Traditional product pages often load all items at once or rely on server-side rendering (SSR).

This causes:
1. Slower initial loads
2. Waste of bandwidth
3. Bad mobile UX

Especially if users don’t scroll past 5 items.

[Krishna Khattri @Khattri_27]

✅ Use lazy loading if:

1. You’re building a SPA or PWA

2. SEO is not the primary concern

3. Your dataset is large

4. You want smoother mobile UX

[Krishna Khattri @Khattri_27]

📦 Implemented lazy loading for product listings using limit + skip API pagination.
Perfect for infinite scroll, mobile performance, and API efficiency.
Here’s why I chose this over SSR (and why you might too):
