Raju is a software craftsman with almost 20 years of hands-on experience scoping, architecting, designing, implementing full stack applications.

He provides a 360 view of the development cycle, is proficient in a variety of programming languages and paradigms, experienced with software development methodologies, as well an expert in infrastructure and tooling.

He has long been in the pursuit of hermeticism across the development stack by championing immutability during development (with languages like Clojure), deployment (leveraging tools like Docker and Kubernetes), and provisioning and configuration via code (toolkits like Ansible, Terraform, Packer, everything-as-code).

The Building Plan: Thinking Architecturally

You are ready to level up your skills. Or, you've already been playing accidental architect, and need to have a structured plan to be designated as one. Well, your wait is over.

From the author of O'Reilly's best-selling “Head First Software Architecture” comes a full-day workshop that covers all that you need to start thinking architecturally. Everything from the difference between design and architecture, and modern description of architecture, to the skills you'll need to develop to become a successful architect, this workshop will be your one stop shop.

We'll cover several topics:

What is architecture, what is design, and the spectrum between them
The modern description of architecture
Understanding architectural characteristics
A brief coverage of some architectural styles
Other skills you need to have to become a successful architect

This is an exercise heavy workshop—so be prepared to put on your architect hat!

Platform Engineering: The What, Why & How

Platform engineering is the latest buzzword, in a industry that already has it's fair share. But what is platform engineering? How does it fit in with DevOps and Developer Experience (DevEx)? And is this something your organization even needs?

In this session we will aim to to dive deep into the world of platform engineering. We will see what platform engineering entails, how it is the logical succession to a successful DevOps implementation, and how it aims to improve the developer experience. We will also uncover the keys to building robust, sustainable platforms for the future

Platform Engineering: The Why, What and How

Microservices + Kubernetes - CrossCuttingConcerns = Istio

Microservices have fundamentally changed the way we develop and deploy applications. Everything from team topologies, to DevOps to observability—everything changed, and for the better.

However, it's not all rainbows and unicorns. Operationalizing microservices is hard. Microservices encourage WET (write everything twice) to ensure that services are as decoupled from each other as possible. But how does that work when we have to deal with cross-cutting concerns that we need for every service?

Enter the service mesh. Service meshes like Istio allow us to “slot” in cross-cutting architectural concerns within a kubernetes cluster, letting our services focus on solving actual business concerns.

In this fast-paced session, we will blitz through what Istio is, how it works, and what facilities it offers to DRY out your microservices. Come see how Istio can make your cluster programmable and application-aware.

Git features you aren't using

Git continues to see improvements daily. However, work (and life) can take over, and we often miss the latest changelog. This means we don't know what changed, and consequently fail to see how we can incorporate those in our usage of Git.

In this session we'll take a tour of some features that you might or might not have heard of, but can significantly improve your workflow and day-to-day interaction with Git.

Head First Git: A Learner's Guide to Understanding Git from the Inside Out

by Raju Gandhi

Many people who use Git rely on "recipes"--copying and pasting commands they find on the internet without really understanding how Git actually works. But what do you do if you find yourself in a tight spot? You can't simply wing it. With this unique hands-on guide, you'll learn the ways of Git and have fun while doing it. Raju Gandhi peels back the layers to reveal the simple yet powerful engine that powers Git, so you'll understand not just the how but the why. You'll master branches, merges, commit messages, search, utilities, and more; learn best practices for collaborative work; and unlock the full potential of Git.

If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. If you haven't, you're in for a treat. With this book, you'll learn Git through a multisensory experience that engages your mind rather than a text-heavy approach that puts you to sleep.

JavaScript Next: Your Complete Guide to the New Features Introduced in JavaScript, Starting from ES6 to ES9

by Raju Gandhi

JavaScript has finally grown up. Armed with a slew of new features, JavaScript now makes writing the code that powers your applications elegant, concise, and easy to understand. This book is a pragmatic guide to the new features introduced in JavaScript, starting with Edition 6 of ECMAScript, and ending with Edition 9.

Using a "compare and contrast" approach, each chapter offers a deep dive into new features, highlighting how best to use them moving forward. As you progress through the book, you'll be offered multiple opportunities to see the new features in action, and in concert with one another.

Backed by an example-driven writing style, you'll learn by doing, and get ready to embrace the new world of JavaScript.

What You'll Learn

Provide a deep exposition of the new features introduced in ES6 through ES9
Review how JavaScript's new features by-pass any limitations of an existing approach
Examine the refactoring necessary to go from old to new
Demonstrate how JavaScript's new features work in unison with each other

Who This Book Is For

New and experienced developers who wish to keep abreast of the changes to JavaScript and deepen their understanding of the language.
