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.

Cinema Room REST Service (Kotlin)

Always wanted to have your private movie theater and screen only the movies you like? You can buy a fancy projector and set it up in a garage, but how can you sell tickets? Having a booth is old-fashioned, so let's create a special service for that! Make good use of Spring and write a REST service that can show the available seats, sell and refund tickets, and display the statistics of your venue. Pass me the popcorn, please!

Web Quiz Engine (Kotlin)

In the Internet, you can often find sites where you need to answer some questions. It can be educational sites, sites with psychological tests, job search services, or just entertaining sites like web quests. The common thing for them is the ability to answer questions (or quizzes) and then see some results. In this project, you will develop a multi-users web service for creating and solving quizzes.
