Norehan Norrizan
Statistician. Engineer. Wanderer.
I hold a Bachelor of Science (Hons.) in Industrial Statistics and have spent my career applying it where it actually matters — inside teams at Fortune 500 companies, across industries, across time zones. Most of what I write here comes from problems I have genuinely encountered, not textbooks I have read.
I have lived and worked internationally, which has a way of clarifying what is universal in software and what is just local convention. Sitting in a meeting where three continents are represented changes how you think about assumptions — in code and everywhere else. The articles here reflect that perspective: precise, opinionated, and written for people who want to understand things, not just use them.
When I am not writing or building, I am usually somewhere new. Travel sharpens the instinct for what matters and what is noise — a surprisingly useful skill in software engineering.
What I Write About
Software Development
Architecture decisions, API design, version control internals, and the practical craft of building systems that work reliably under real load.
Programming Concepts
Algorithms, complexity, type systems, and language internals — the foundational ideas that remain relevant regardless of which framework is popular this quarter.
Statistics & Data
The statistical thinking every developer benefits from: A/B testing, regression analysis, probability, and how to interpret data honestly rather than selectively. This is my background — I write it from the inside.
Editorial Standard
Most technical content is either too shallow — a five-minute tutorial that skips everything interesting — or too dense — a research paper written for reviewers, not readers. I aim for the middle ground: thorough enough to be genuinely useful, precise enough to be honest.
I do not publish on a schedule. I publish when I have something worth saying. Quality over frequency.
Built With
This site is built with Next.js 15 (App Router), TypeScript, and Tailwind CSS. Fonts are loaded via next/font — no render-blocking requests, no external stylesheets. No trackers beyond basic analytics, no dark patterns, no cookie walls.
