Kotlin in the New Era

From Android Apps to MVPs, AI Features, and Scalable Backend Systems — 3 Days

Introduction

Why this course

Kotlin has grown far beyond its early reputation as a cleaner way to write Android code. Today, Kotlin developers are expected to understand how mobile apps connect with APIs, cloud services, security layers, data streams, AI features, and product goals. A modern app is rarely just an app; it is usually one part of a wider digital product.

This course is designed to help Kotlin and Android developers move from feature-level development to product-aware engineering. Participants will learn how to build stronger Kotlin applications, structure code more clearly, apply MVVM correctly, improve performance, secure applications, integrate AI, and understand how mobile systems connect with backend and cloud services.

A key part of the course is the MVP, or Minimum Viable Product, mindset. Participants will learn how to identify the smallest useful version of a product, build it properly, validate it early, and improve it based on real needs rather than assumptions.

The course will be led by an instructor with over 30 years of industry experience, using real industry-demanded content rather than overly academic material. The latest Kotlin ecosystem continues to support mobile, server-side, desktop, web, and multiplatform development, while recent Android 16 changes place stronger emphasis on security, privacy, behavior changes, and app compatibility.
