What you'll learn

While working on the projects of this course, you will:

  • Apply key features and advanced libraries in Kotlin, such as Exposed, SQLDelight, Firebase, and others;
  • Understand concepts of cryptography, data access, networking, serialization, concurrency, reactive programming, and dependency injection.
  • Utilize Kotlin libraries to build applications with secure data handling, efficient networking, and robust data access;
  • Implement reactive programming techniques to create real-time updates and responsive systems;
  • Distinguish between different concurrency management techniques and evaluate their effectiveness in various scenarios;

Learn by doing

# 1
Apply knowledge into practice
You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.
# 2
Navigate complexity with surgical precision
Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.
# 3
Copy the best. Then improve.
Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.
# 4
Code review that actually makes you better
We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.

Elevate your engineering mastery through real-world challenges

Master advanced engineering concepts through ambitious projects. Each project deepens your expertise and transforms you from an experienced engineer into an exceptional one.

Indigo Card Game

In this project, you will create a simple card game called Indigo. It has simple rules, but it can also be the foundation for developing a more complex card game. You will create a virtual card deck and implement the game rules, scoring system, and a simple strategy for the program to compete against users.

Parking Lot

Cities are becoming smarter to meet our needs, and parking spaces are an essential part of urban design. As a developer, you can help improve them. In this project, you will create a parking lot management program that keeps track of vacant spots and parked cars.

Unit Converter

When you travel, everything changes: people, languages, time zones, and even units. It may be difficult to read the temperature in Fahrenheit when you’ve always used Celsius, or to measure yourself in kilos if you’ve only used pounds. It’s no easy matter, though a nice unit converter could certainly help! In this project, you will write a converter that handles distance, weight, and temperature units – all the traveller’s essentials.
