In-depth guides on Android, Kotlin Multiplatform, iOS, web development, software architecture, and engineering careers. Written by David Cruz Anaya, a Senior Android & Kotlin Multiplatform engineer based in London and author of You Are Not That Important.
A practical guide to Kotlin's inline, crossinline, noinline, reified, and where keywords, with code examples showing when each one matters and how they fit together.
A practical guide to deciding when C++ belongs in an Android app. Learn the real use cases (audio, games, heavy compute, cross-platform cores), the hidden costs of the NDK and JNI, and a simple decision framework so you reach for native code only when it actually pays off.
After a redundancy or stalled senior-level job hunt, repeated rejections turn impostor reading into learned helplessness. The chain, the science, and the climb out for software developers.
