Arunveer Singh · Engineering judgment, in public

Reason fromfirst principles

AI should force you not to make mistakes.

I write, teach, and ship the standard I want tools to hold. The public artifact is arunveersingh/ai — 11 agent skills that refuse to proceed on a guess. I teach the same standard in English and Hindi. Tutorials stay in the library. Judgment stays here.

Writing

Slowness vs latency — use the right word

Latency is a measurement. Slowness is a feeling. Mixing them up wastes the conversation.

Eliminating null in Java

Null is design-time uncertainty encoded at runtime. Patterns that take it out of the system.

The trouble with void methods

Void methods hide outcomes. That makes tests brittle and intent harder to read.

Managing Null in the Spring Framework / Spring Boot: Advanced Strategies for Null-Free Architectures
