Get out of technical debt without big upfront time investment? Professionally articulate technical decisions to your team and management? Build remarkable engineering career?

Then this course is for you.

During this intensive, practical and entertaining 2-day course you will learn principles, practices and patterns for writing readable, maintainable and effective code.

The course is based on real-world project code, stories and examples
The course includes practical Lab work
The course is updated to support Java 9 and functional programming idioms
The course will show many frameworks in action including Spring, Hystrix and others
The course runs in a small group with a lot of discussion and experience exchange
Attendees will receive optional coding assignment for skill polishing. Homework will be reviewed and supplemented by constructive feedback.

Coverage

Software development economy (clean code rationale, design entropy, busting "quality is expensive" myth, consequences of bad code)

Principles, rules, laws and dilemmas (use-reuse paradox, specific-generic dilemma, Law of Demeter, KISS, SOLID, DRY, YAGNI, just-enough design)

Clean coding practices

Effective Naming (principle of least astonishment, command-query separation, eliminating getters and setters, side-effects)

Effective Conditionals (how and when to avoid branching, how to eliminate nested branching, making branching easy-to-read)

Effective Functions (nulls vs. optionals, single level of abstraction, step-down rule, lambda or not to lambda?)

Effective Classes (OO meets functional, objects vs. data structures, abstraction, coupling, cohesion)

Effective Comments (when and how to avoid, alternatives)

Effective Application Layer (commands, reactions, funnels)

Effective Domain modeling (DDD, protecting invariants, value objects, entities, aggregates, event bus, strong and eventual consistency)

Effective Persistence (transaction management, unit of work pattern, DAO vs. repository, testing data)

Effective Validation (simple and complex rule validation, why Bean Validation sucks, writing custom validator)

Effective Exception Handling (when and how to handle exceptions, designing exception hierarchy, checked vs. unchecked)

Effective Resilience (failure modes, responding to failures, stability patterns, Hystrix)

Effective Concurrency (CompletableFuture, RxJava, testing concurrency and asynchrony)

How to stay clean and move fast (incremental refactoring, effective code reviews, pairing, CoPs, brown-bags, quality forecasting with Sonar)

… and much more!

I wanted to know how I could improve the quality of my code and your course gave me some tools to achieve that. I liked that it was about more than writing code. You gave some tips on how to deal with management and what you can do as a developer to change that for the better and that you need to stay true to yourself. I like that the course doesn't really end's here. That there is homework and that you encourage us to stay in contact. You inspired me to become a better developer and gave me the energy to become the best that I can be. β€” πŸ‡§πŸ‡ͺ Liesbeth de Keyzer
The course was absolutely above expectations. Usually courses just reuse "Clean code" book and provide some "common sense" recommendations. But not this one! More than 95% of information was top new and mind-blowing. I've got new practical tips to use in my everyday work and a completely new look on the things I do. Moreover, it inspired me for further growth as a professional and gave different directions, how to do it! Thanks, Eduard, this was the best training I ever attended! β€” πŸ‡±πŸ‡» Alex Kartisevs
This was the most advanced and best course I've been on! Very entertaining! I learned that I should use more functional Java and that courses can be fun. β€” πŸ‡ΈπŸ‡ͺ Jahziah Wagner
