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.

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

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.

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

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.
