High traffic app?

Don’t make reads and writes share the same path.

CQRS separates them, making it easier to scale what users do most: read data.

@OpenAI We went from:

Idea → Specs → Design → Dev → Deploy

to:

Idea → URL

Wild times for software engineering.

@surface Power is great.

What I am curious about is battery life under real AI workloads 👀

Anyone can split a database into shards.

The hard part is picking a shard key that still works when traffic is 100× higher.

Circuit Breaker is the seatbelt of microservices.

When one service crashes, it prevents the failure from spreading across the entire system.

Small pattern. Huge impact.

Cache is king in system design.

But cache invalidation? That’s where even seniors lose sleep.

Load balancers don’t just distribute traffic.
They stop your single server from becoming the bottleneck when users flood in

Backend engineering is basically:

“Everything is working fine”

until one small config changes and suddenly:

Kafka stops consuming
Redis starts timing out
one microservice dies silently
alerts explode at 2AM

Most backend bugs aren’t hard.

Finding them is.

Backend engineering is basically:

fixing one issue,
creating two new ones,
then acting surprised in production.

Most backend bugs are just:
one config change + pain + confusion.

I enjoy backend work because most improvements are invisible to users.

Faster response times.
Better reliability.
Cleaner architecture.

Nobody notices when things work smoothly

[StackPilot @TheStackPilot]

A lot of engineering growth comes from debugging systems you didn’t build yourself.

That’s where you really learn to read code carefully.
