Why our Code Review Services?

Code review or Peer review is a complex of actions aimed to improve the end-quality of program code. During this process, third-party developers usually review source code to find any type of mistakes, check the architecture correctness and offer better solutions. It’s crucial to have reviewers outside the circle of people who developed the initial code to assure the high quality and impartiality of the code review. Generally, code review service streamlines and accelerates the process of software development like only a few other practices can.

Why source code review is important?

It’s obvious that as any software is created by humans, it can often be done with some mistakes, mistypes, security bugs, architectural errors, business logic flaws, and many more limitations. When knowing and realizing this, it’s much easier and quicker to make fixes and improvements during and after the code review process compared to when found by QAs in the product already compiled. This means that code review service saves a lot of time and, eventually, money, especially if otherwise the bugs would be found only after the product went public.

Code Review Checklist

General Overview

Includes gathering general information about the project like the list of the used technologies and frameworks, the number of code lines, the list of main features to be reviewed, general stats about issues, both recommended fixing, and critical ones.

Code Metrics

Includes information about the main code metrics and their calculation provided by code reviewers, e.g. Maintainability Index, Cyclomatic Complexity, Depth of Inheritance, Class Coupling and more.

Architecture review

Includes information about the architecture of solution – how the core is constructed, what are the modules included, used the appropriate architecture principles and patterns. The code should follow the defined architecture, whatever the architecture is MVC, MVP, MVVM we should be sure what code is following it. Checking if the solution code is clean. It should follow Object-oriented analysis and design (OOAD) principles or SOLID principles.

UI review

The analysis of how UI is implemented from the code perspective. In the case of a mobile application, we should check if the solution follows the style’s guidelines for specify platform. It’s required because style violations can lead to a problem with publishing to a specific store.

Tests review

Includes an analysis of unit tests, code coverage, tests’ quality. Checking the failure conditions, checking easy to read, checking the speed of execution, etc.

Code Quality review

This point lists all the issues of different categories with their detailed descriptions. All the issues are categorized as either recommended to fix issues or critical ones. This point has also to include information if the code should be simplified, if it’s poorly commented or if there are any other problems with code: hardcoded values, unused methods, and variables, too complex or big methods, etc.


And the last point is Recommendations, which generally include the explanation of recommended fixes and improvements, a recommended sequence of changes and the estimated resolution time.

Code Review & Audit Benefits

Independent Audit

Do you feel like your latest software project isn’t on track? Redwerk can eliminate your stress, and provide you with a quick and thorough independent software audit. We’ll align your software development process with your company’s true vision, and ultimately help you create a plan that leads to a successful software project.

Unbiased Perspective

We only want the best for our clients. So, we’ll approach your project from a true third-party perspective. Redwerk will assess your software’s plan, code quality, and maintenance as an unbiased spectator. This ensures that you receive a fair, high-quality audit that helps you achieve your goals.

Vulnerabilities Check

To rescue your software from unexpected hackers’ attacks make sure to apply Code Review that helps in discovering the vulnerabilities in your code. You may not know about every single flaw in a chosen technology. And a careful review with a fresh look will help to identify all the problem areas to design more reliable and secure applications.

Efficient Testing

CR should be used not only for code that is ready to go into production, but generally for everything. Its time span is not huge, but the difference in quality turns out to be enormous. Test planning and conduction often take much more time than looking through the code lines. CR saves a lot on testing and assists in choosing the most suitable methods.

In-depth Project Analysis

Two heads are better than one. Code Review helps to spread knowledge about the project among the team. At least one other person will review your code before it is tested in real conditions (bugs). Both the original developer himself and the reviewers can understand the application logic better.

Code Quality Maintenance

Code review is not always about mistakes and faults. Code quality deteriorates over the life cycle of an application. Updating the architecture, adding new features, and fixing bugs on systems with poor code quality takes longer and results in even more bugs. We can help you make sure that your code remains clean and workable.
