This article explores what these numbers are, where they come from, why they are concentrated in Nuwara Eliya, how they function today, and the ongoing debate about their abolition. The British Plantation Economy (1820s–1948) When the British colonized the central hills of Sri Lanka (then Ceylon), they converted dense jungle into vast tea, coffee, and cinchona plantations. The indigenous Sinhalese population was reluctant to work on these estates under grueling conditions. The solution? Importing Tamil laborers from the Madras Presidency of India.

Introduction: More Than Just a Number
In the mist-shrouded highlands of Nuwara Eliya, Sri Lanka—often called "Little England" for its colonial-era bungalows and rolling tea estates—there exists a unique, deeply ingrained numeric code that has defined a community for nearly two centuries. Locally referred to as (derived from the Tamil word Badu , meaning labor or coolie), these identifiers are officially known as Estate Labour Registration Numbers . The solution
For the average tourist sipping a cup of Ceylon Tea at a hillside hotel, these numbers are invisible. But for the Malaiyaha Tamil community—the descendants of indentured laborers brought from South India during British rule—the "Nuwara Eliya Badu Numbers" are a passport to existence. They are simultaneously a historical relic, a bureaucratic necessity, and a controversial marker of identity.
The book is separated into six standalone parts, each part covering several chapters:
Parts 1 and 6 apply to all engineering levels: from entry-level software developers to principal or above engineers. Parts 2, 3, 4 and 5 cover increasingly senior engineering levels. These four parts group topics in chapters – such as ones on software engineering, collaboration, getting things done, and so on.
This book is more of a reference book that you can refer back to, as you grow in your career. I suggest skimming over the career levels and chapters that you are familiar with, and focus reading on topics you struggle with, or career levels where you are aiming to get to. Keep in mind that expectations can vary greatly between companies.
In this book, I’ve aimed to align the topics and leveling definitions closer to what is typical at Big Tech and scaleups: but you might find some of the topics relevant for lower career levels in later chapters. For example, we cover logging, montiroing and oncall in Part 5: “Reliable software systems” in-depth: but it’s useful – and oftentimes necessary! – to know about these practices below the staff engineer levels.
The Software Engineer's Guidebook is available in multiple languages:
You should now be able to ask your local book shops to order the book for you via Ingram Spark Print-on-demand - using the ISBN code 9789083381824. I'm also working on making the paperback more accessible in additional regions, including translated versions. Please share details here if you're unable to get the book in your country and I'll aim to remedy the situation.
I'd like to think so! The book can help you get ideas on how to help software engineers on your team grow. And if you are a hands-on engineering manager (which I hope you might be!) then you can apply the topics yourself! I wrote more about staying hands-on as an engineering manager or lead in The Pragmatic Engineer Newsletter.
I've gotten this variation of a question from Data Engineers, ML Engineers, designers and SREs. See the more detailed table of contents and the "Look inside" sample to get a better idea of the contents of the book. I have written this book with software engineers as the target group, and the bulk of the book applies for them. Part 1 is more generally applicable career advice: but that's still smaller subset of the book.
