Case Study: Klarna’s AI Transformation and What Businesses Can Learn from It

-
Case Study: Klarna’s AI Transformation and What Businesses Can Learn from It Klarna has become one of the most referenced examples of enterprise AI adoption—not because of a single tool, but because of how it restructured its internal systems to make AI useful at scale. A key part of this transformation is its internal AI assistant, “Kiki,” which is widely used by employees to access company knowledge instantly. The Problem Klarna Faced Like many large organizations, Klarna had accumulated a wide range of SaaS tools over time: CRM systems HR platforms Documentation tools Internal communication systems Project management tools While each system solved a specific need, they created a larger problem: 👉 Critical business knowledge was fragmented across multiple platforms. This meant employees often had to search across several systems just to answer simple operational questions. The Shift in Approach Instead of starting with AI tools, Klarna focused on a foundational issue: 👉 How company...

Kotlin Crash course

-
 Kotlin var greeting: String = "Hi" val name: String = "Malathi" we can reassign value to variable defined using var but not val. By default Strings in Kotlin are non null values. To make them nullable, we should use ? operand like below val name: String? = "Malathi" Ex: fun main() {    var greeting: String = "Hi"    val name: String = "Malathi"    println(greeting)    println(name) } Kotlin has type inference. It means that the type is automatically detected based on the value assigned to the variable. So var greeting = "Hi" statement too works. Control loops if statement: if(greeting != null) { println("if statement")} while statement: It is similar to Switch statement in Java while(greeting) {    null -> println("Hi")    else -> println(greeting) }  val greetingToInvite = if(greeting != null) greeting else "Hi" println(greetingToInvite) val greetingToInvite = when(greeting) {    null -...

Java 13 Features

-
This post is the introduction of commonly used Java 13 features.  Switch expressions: This is still in Preview stage in Java 13 version. The main difference about switch expressions in Java 12 and Java 13 is the introduction of Yeild in Java 13.  Yeild is used to differentiate between Switch statements (Java 11 or less) and Switch expressions (Java 12 or more).  Primarily the new Switch expressions eliminates the need of break statement and also multiple case statements.  Eliminating the break statement reduces lot of verbosity and no need for developers to remember it whenever they use switch. Accidentally if developers forget about adding break statement, it introduces bugs and deviate application to meet business requirements. So using Switch expressions improves efficiency of the code and increases productivity.  Earlier multiple case statements introduced lot of boilerplate code. But with introduction of Switch expressions, we can simply group the related t...

There are some interesting and useful features available in Java 12. However some are in Preview stage, not for production use. All Preview features are labelled accordingly. Compact Number Formatting Java 12 comes with number formatter the CompactNumberFormat. It was designed to represent number in shorter form based on patterns provided by given locale. NumberFormat shortNumber = NumberFormat.getCompatcNumberInstance(new Locale("en", "US"), NumberFormat.Style.SHORT); shortNumber.format(1000); output: 10k Try what output you get when you try Style.LONG. Teeing Collector in Stream API Collector<T, ?, R> teeing(Collector<? super T, ?, R1> downstream1, Collector<? super T, ?, R2> downstream2, BiFunction<? super R1, ? super R2, R> merger) Every element is processed by both the downstream collectors and their results are passed to merger function. The example of teeing collector is shown below If we want to calculate average from set of num...
