I have been in backend development for more than 15 years. It is a challenging field and It took me some time to find my path to becoming a good one. But if I started over, these are the 6 steps I would follow. 1 of 6.

Your system isn’t slow because of your code. It’s slow because of your choices. Here’s what actually kills software:. - You chased microservices before understanding the domain. - You made everything async, then couldn’t trace a single bug. - You “overengineered” thinking you

Observability often dies on bloated dashboards. A friend called me last week. He was trying to figure out why a new feature was running slow. Half a day gone. Thousands of log lines later, he had a guess. Not an answer. That’s the reality for most teams today:. 1. You log

I’ve seen firsthand how too many meetings kill focus and slow down real progress. That’s why I write about practical cases to build better systems in my newsletter. And build a platform to practice System Design, one question a day.

Meeting-Driven Development is real. And it’s killing your progress. We’ve normalized a workflow where talking about work has replaced actually doing the work. - 30 minutes of standup.- 1 hour of grooming.- 1 hour of retro.- 1 hour of “alignment”.- 45 minutes for “sync”. And

Caching is easy to add. Hard to get right. Here are 7 caching concepts that separate a good system from a fragile one:. 1. Cache Hit Ratio. This tells you how often the cache serves a request. A high hit ratio = fewer slow database calls. If you're not tracking this, you're

Most teams over-orchestrate their microservices. They think they need a central conductor to coordinate every step. But the more tightly you control the flow, the more brittle your system becomes. I used to believe orchestration was the safest choice. Clear logic. Easy

Most database dilemmas aren’t about SQL; they’re about trade-offs. Yesterday’s question was a classic:. Should you denormalize tables to improve read performance, even if it hurts write consistency?. Here’s the setup:. - Alex applied BCNF (Boyce-Codd Normal Form) to eliminate
