How to hire Top Yii Developers


Hiring Yii developers, whether for a startup or a larger company, requires careful consideration of their technical skills, experience, work style, and fit within your organization, with your internal team members.

Yii developers need strong technical skills, including extensive knowledge of the Yii framework, PHP, and relational databases, and the ability to create RESTful APIs and work with front-end technologies. They also need experience with testing methodologies, version control systems, and problem-solving. In a startup environment, these skills may need to be more broad and adaptable, as the developer could be required to wear multiple hats and tackle tasks outside their usual purview. In contrast, a larger company might require a more specialized skill set, with developers focusing more narrowly on specific parts of the system.

Working style is another important factor. A Yii programmer for a startup often needs to be flexible, innovative, and comfortable with a fast-paced, sometimes chaotic environment. They should be prepared for a steep learning curve and a dynamic, rapidly evolving workload. On the other hand, a Yii developer for a larger company might need to be more methodical, with a strong emphasis on processes, documentation, and coordination with larger, more defined teams.

The choice between hiring a full-time Yii developer versus a part-time or contract-based one depends on your business needs, the project size, duration, and budget. Full-time developers can provide continuity and a deeper understanding of your project over time, making them suitable for long-term, complex project management. This could include website development, mobile app development, web design,  or finding innovative web solutions. However, they are generally more expensive and involve responsibilities like benefits and insurance. On the other hand, part-time or contract-based developers can be more cost-effective and flexible, making them a good choice for short-term projects or for tasks that require specialized skills not present in your current team, perhaps plugin implementation and optimization or shorter-term software development. 

Cultural fit is essential regardless of company size or hiring model. The developer needs to align with your company's values, work culture, and goals. This is especially crucial in startups, which often have unique cultures and higher expectations for employee engagement. They should be able to answer FAQs and collaborate across multiple time zones with internal development teams in addition to their background in back-end development and quality assurance.

To summarize, hiring a Yii software engineer requires balancing their technical skills, experience, working style, and cultural fit with the needs of your project and your organization. Whether you're a startup looking for a flexible, broad-skilled developer or a large company seeking a specialist, you need a Yii developer who can efficiently and effectively contribute to your web development projects.

Yii Framework Knowledge

A proficient Yii developer must possess comprehensive knowledge and experience with Yii framework development, including the latest versions while being fluent in other programming languages. They should be comfortable working with both Yii 1 and Yii 2, depending on the requirements of your project. They should have a strong understanding of the Model-View-Controller (MVC) design pattern that Yii websites follow, which enables the efficient organization of code into logical, manageable components. Moreover, the developer should be adept at using Yii's advanced features such as DAO (Database Access Object), ActiveRecord for database ORM, and caching mechanisms for performance optimization. They should be capable of integrating AJAX support using jQuery-based AJAX features provided by Yii. Understanding of Yii's form input and validation, theming and skinning, and security measures like XSS, CSRF, and cookie attacks is also vital. Proficiency with Gii, the powerful web-based and console-mode code generator tool provided by Yii, is another desirable skill.

Proficiency in PHP

Yii is built on PHP, hence a Yii developer should have profound knowledge and experience in PHP programming. They should understand the basic syntax, semantics, and data types of PHP, along with more advanced PHP topics. This includes object-oriented PHP for creating complex applications, PHP namespaces for organizing code, and traits for code reusability. Developers should also be familiar with error and exception handling in PHP. Understanding PHP's native functions, such as string and array functions, is equally essential. Familiarity with PHP 7's features, like return type declarations, null coalescing operator, spaceship operator, etc., could be beneficial, depending upon your project's PHP version.

Database Knowledge

Yii developers should be skilled in working with relational databases, such as MySQL, PostgreSQL, and SQLite, as Yii applications often involve heavy database interaction. They should understand SQL queries and transactions, database schemas, indexing, and other related concepts. Their skills should extend to Yii's ActiveRecord, which provides an object-oriented interface for accessing and manipulating data stored in databases. It's important for them to have experience in database migration for managing database changes and maintaining its schema. Familiarity with database abstraction layers and understanding the interaction of PHP with different databases will be an added advantage.

Front-End Technology Skills

While primarily focusing on back-end, server-side logic, a Yii software developer often needs to interact with the front-end of an application. Therefore, it's important they have a working knowledge of HTML, CSS, and JavaScript. They should be capable of creating or altering user interfaces and understand how Yii's view rendering works. They should also be familiar with JavaScript libraries such as jQuery and frameworks like Vue.js or React, if your project requires it. Understanding CSS preprocessors (like SASS or LESS) and the ability to work with responsive design frameworks such as Bootstrap can be highly beneficial. Additionally, a solid grasp of AJAX, which helps in creating faster and more interactive web applications, is a vital skill for Yii developers.

Understanding of RESTful API Development

In modern web development, APIs play a crucial role, and a Yii developer should be well-versed in creating and managing RESTful APIs. Yii provides excellent support for building APIs, and a proficient developer should know how to leverage these capabilities. They should understand concepts such as HTTP methods (GET, POST, PUT, DELETE), status codes, API endpoints, and request-response structures. Familiarity with principles of URL design and API versioning is important too. They should also know how to manage authentication and authorization, possibly through OAuth or JWT (JSON Web Tokens), to secure the API. Tools such as Postman or Swagger for API testing and documentation can be beneficial.

Experience with Testing

An experienced Yii developer should have a solid understanding of various testing methodologies to ensure the robustness and functionality of their code. Yii uses Codeception, a multi-featured testing framework, and developers should be proficient in using it. This includes writing unit tests, which test individual components, and functional tests, which test the interaction between components. Understanding of concepts like test-driven development (TDD) and behavior-driven development (BDD) is beneficial. They should also be familiar with mocking objects and services for testing, and continuous integration tools like Jenkins or Travis CI for automating testing processes.

Knowledge of Version Control Systems

Version control systems are essential tools for managing changes in code, especially in collaborative environments. The most commonly used system is Git. A dedicated Yii developer should be adept at using Git or a similar system for versioning, merging, branching, and managing repositories. They should understand how to resolve conflicts during merges and how to revert to a previous version if necessary. Knowledge of GitHub, GitLab, or Bitbucket for hosting repositories and managing collaboration is also important. If your team practices Continuous Integration/Continuous Deployment (CI/CD), experience with related tools would be beneficial.

Problem-Solving Skills & Experience

Alongside technical skills, a full stack developer should possess strong problem-solving abilities acquired through extensive years of experience. This involves the capacity to think logically, analyze the requirements of a task, and create an efficient solution. A skilled Yii developer should have experience solving complex programming problems, debugging code, and working with existing code bases. Tools like Xdebug for PHP can aid in this process. They should be comfortable working in different development environments and adapt to the specific tools and processes used in your organization. Reviewing their past projects and asking for examples of how they have solved complex problems in the past can help evaluate these skills. Moreover, they should have experience with performance optimization and security best practices in Yii applications.
