A creative roadmap for backend devs.

How to reduce duplication in Python unittest suites by sharing common test logic across multiple test classes.

A practical walkthrough for generating type-safe Go code directly from OpenAPI specifications using oapi-codegen.

An exploration of Behavior-Driven Development in Go using GoDog, focusing on mindset, executable specifications, and writing tests that describe system behavior.

Knowing Go syntax is table stakes. Real Go engineering is about judgment, restraint, and knowing when the language itself is the wrong tool.

Cache stampede is when your own users become the attack. The fix is not more cache — it is treating the cache miss path like a critical section.

You type a username. Before you finish, it’s already taken. No network call. No lag. How?

The order you write a SQL query and the order the database executes it are completely different — and that gap explains most SQL mistakes.

DDD is not about folder naming. Here is my lightweight take — what actually works, what gets abused, and when to just start small.

Come to think of it , Slack is not a chat app. It’s a multi-tenant distributed system wearing a friendly UI. The lessons from how it handles isolation, fanout, and noisy neighbors apply far beyond messaging.

Most Go services start clean and turn into a tangle. Hexagonal architecture is the structural idea that keeps them untangled — here is how it works and how to apply it in Go.

A creative exploration of Foreign Function Interfaces (FFI) — how they enable interoperability, reuse, and integration across programming languages.

An in-depth exploration of backpressure in distributed systems — why it arises, how it impacts stability and throughput, and the strategies engineers use to handle it effectively.

A deep dive into escape analysis in Go — how the compiler decides whether variables live on the stack or heap, and why it matters for performance.

Everyone knows how to add a cache. Almost no one has a written-down invalidation strategy before shipping.
