Sources to Hire Best PHP Developer
As you’ve defined the type and number of PHP developers you need for building a successful product, it’s time to search for them. There are several sources for hiring PHP developers, the main ones are:
PHP has a well-established community that helps its members to solve tough project issues or shares ready-made features and programming solutions. These communities unite PHP developers with various levels of expertise and experience. The most widespread of them include Github, PHP forums such as CodeProject, CodeGuru, and others.
- Freelance sites and portals
There is a wide range of specialized sites and portals that offer freelance PHP development services. Freelance developers work great for small and short-term projects which require developing some app functionality without much wrapping in the whole project. Major freelance platforms include Upwork, Freelancer, Toptal, and others.
PHP development companies provide businesses with experienced PHP developers in various spheres. They include custom development of procurement management systems, e-commerce, social network development, HRM, E-learning, and many other solutions.
When choosing a PHP development company, businesses obtain a team of professionals who can build even the most sophisticated infrastructures. Moreover, these companies often provide full-stack PHP developers for creating full-featured, robust, and secure web apps.
Technical Questions to Check the PHP Developer’s Capabilities
To define the level of PHP developers’ expertise, business managers usually check out their reviews on freelance platforms or PHP development company’s sites. However, nothing works better than a face-to-face interview. For an effective interview with PHP candidates, you need a list of questions and a well-organized video conference.
A list of questions for a hiring interview with PHP developers:
- What is your practical experience in PHP development? What projects have you participated in?
These questions will help you to identify the working experience of a candidate and understand their skill level.
- What were the most interesting projects and why? What technologies did you have to use when working on that project?
This will help you to understand better the tech-stack of a software developer and find out the most interesting areas of work for them.
- Which technologies and frameworks do you know? Which of them do you use in your daily work?
These questions specify the tech stack and all the tech skills a developer has. For example, knowledge of most wide-spread frameworks like Yii, Laravel, CodeIgniter, object-oriented PHP programming, code versioning tools like Git, Mercurial, CVS, and databases like relational and NoSQL is a must for a good PHP developer.
- What was the most challenging development issue in one of your projects? How did you solve them?
These questions show a software developer’s course of action in case of unpredictable situations.
- What was the most creative solution you implemented in your past projects?
This question shows how creative a PHP developer can be in their work. The more they blend technologies the more unconventional and modern a product can be.
What Costs You Need to Incur When Hiring a PHP Developer
There are many factors that influence PHP software developers’ hiring prices. Therefore, instead of opting for the first solution, businesses need to examine the market proposal and consider all the factors.
Here are the key elements that determine pricing in PHP development.
Type of Cooperation
Hiring freelancers is always cheaper than onboarding an in-house team or referring to an outsourcing development company. However, with freelancers, you may run into further expenses if a project appears to be too complex, require deep engagement, or extensive expertise.
If you’re hesitating between an in-house team and an outsourcing company, study all of their pros and cons for your project. For example, in-house teams work great for long-term projects with high participation levels. While outsourcing providers can offer lower PHP developer hourly rates, wider access to a PHP developer’s talent pool, full-cycle development projects, and many others.
Proficiency Levels of PHP Developers
Beginners have the lowest rates, while professional developers get seriously expensive. Therefore, business managers have to evaluate their projects and decide how many developers they need and which level of expertise they should possess.
It’s obvious that the complexity of an implemented technology determines the price of the final product. If you decide to embed a complex solution in your web app, you need to decide first if it drastically affects your app’s functionality or if it is just an additional feature.
To understand how well one or another technology will suit your product, you need to perform a deep project and product analysis. Most of the development companies provide this service to their customers, calculating expenses, selecting the best technologies for an app, and gathering the best development teams.
Using the PHP programming language for building web apps has been a long-lasting tradition in web development. In 2021, PHP remains relevant and supports 79.1% of the world’s websites. Therefore, building web apps with PHP is an optimal and effective solution for many businesses.
When hiring PHP web developers, businesses need to consider several factors to avoid exceeding their project budgets and build effective and secure apps. These factors include PHP developers’ skill sets, whether they hire freelancers, in-house teams, full-time PHP developers or opt for outsourcing companies, developed technology, and others.
