Key Skills of Developers An Important Factor During Hiring


magento logo
Magento is mainly an e-commerce application that was launched on 31st March 2008. It is a very powerful ecommerce system with a steep learning curve and which is mainly aimed at larger ecommerce sites. Magento was built using the Zend Framework and uses the Entity Attribute Value (EAV) data base model to store the data.
A developer working on Magento is expected to have strong knowledge in building B2B and B2C e-commerce products/solutions. Magento developers is also expected to possess strong knowledge and good amount of experience on LAMP stack, JavaScript/query, Magento, HTML, CSS, API platforms and agile processes.
The following are some more of the skills that Magento Developers are expected to have:
A Magento developer has to have the ability to build a new customized website as opposed to using just the templates and building the sites. She/he needs to have good knowledge on most of the Magento extensions that can be used in the application or website that is desired. For a developer working on Magento, it is important to keep a track of all the objects/variables, etc. that are being used in the application.
Apart from the above mentioned attributes, the developer must also showcase strong knowledge in the development of Customized modules, in the upgrading process, design integration, integrations of payment gateways and maintaining websites using Magento platform.
Another important skill to look at in a Magento developer is Search Engine Optimization (SEO). A developer needs to have the ability to optimize the website to draw good amount of traffic to itself. So it will be a good to have skill if the developer knows various functions of SEO.
With the immense boom of smart phones, having knowledge on mobile development is an equally important aspect to look at in a prospective Magento developer. Most customers these days prefer to access sites from their mobile devices than the actual browser. So a prospective Magento developer needs to have the ability to innovate and code directly for mobile devices.
Having the skills is one thing. Being able to put the skills to use in an efficient and bug-free way is a totally new skill in itself. If a developer has the knowledge on all the required skills but writes code that is riddled with bugs is not a good fit for the job. A magento developer who writes code that is both clean and bug free is a good fit for the job.
Apart from these, the developer needs to be able to provide support and maintenance to the sites. The developer also has to be able to upgrade the site as and when latest upgrades are pushed.

joomla logo
Joomla is one of the most popular CMS products available for medium to large sites that need more flexibility and features than WordPress supports. There are more plug-ins for Joomla than any other CMS, which gives it huge flexibility and extensibility.
For hiring a developer to work on Joomla, there are 4 things to consider before the developer can be interviewed.
1.If an EXTENSION DEVELOPER is required, the developer is expected to have strong technical knowledge and ability to create custom extensions that can be used in Joomla. She/he should also have the ability to use their knowledge of working of the CMS in order to solve problems based on functionalities.
2.If a TEMPLATE SKIN DESIGNER is required, then the developer is expected to have demonstrated strong HTML and CSS skills to create a skin for the joomla website by looking at any design that is desired. Basically, they are graphical designers that create the look and feel of the Joomla website.
3.If a SITE DEVELOPER is required, then the developer is expected to have strong knowledge and experience in using the already built or created extensions and templates. The developer makes use of this knowledge to develop the sites as per requirements. The developer is not expected to have high technical knowledge but knowledge on graphical presentation is preferable.
4.If a WEB DESIGNER is required, then the developer is expected to have pretty much the same skill set as a Template skin designer along with the ability to create custom designs and alter existing designs

HTML Developer:

html and css
HTML is the mark-up language used for creating the front-end of web applications. So, for obvious reasons, the very basic skill required for a developer to be hired as an HTML developer is that the developer has very strong knowledge and understanding of the HTML mark-up.
But knowing just HTML is not sufficient as websites today have already moved to be more and more intuitive and interactive and dynamic. So the developer is also expected to know scripting languages like JavaScript, jQuery, etc. to make the page more interactive and responsive.
With importance to client side processing increasing, there is an even more push for developers to learn many JavaScript libraries like Knockout.js, Angular.js, Node.js and others. These technologies not only reduce the burden of writing extra server side code but also improve the performance of the website immensely.
Some of the tasks that a front end developer specifically has are:
a.Creating, customizing and maintaining the front-end design of the website and the user interface.
b.Creating and editing templates for a web development framework.
c.Creating, editing or modifying templates for a CMS or web development framework.
d.Working on the styles and animations to the web pages in the web site.
e.Working with web designers to turn their static pages into interactive and intuitive working web pages.
f.Working with back end developers in implementing their code to develop interactive and dynamic web pages.
g.Modifying the content that is displayed on the website to the user.
h.Updating the website technologies with the latest updates as and when they are pushed in to the real world.

PHP Developer:

php and mysql
PHP is one of the most common server side scripting language that is widely used for web development. It is interpreted by the web server with a PHP processor module, which generates the resulting web page.
PHP provides lot of commands that can be directly included in the HTML mark up rather than calling an external file to process the data required. PHP can also be used in standalone graphical applications.
With the boom in mobile applications, Zend framework announced the Zend Studio which can be used to develop platform independent mobile applications using PHP. This proved to be a huge hit with PHP developers.
Some of the skills that a PHP developer is expected to know are:
Every PHP developer is expected to know at least some of these frameworks and is expected to have expertise in at least one of them.
a.Zend framework
The developer should be able to write code samples and explain them properly.
The developer is also expected to know how to debug the application in PHP. Knowledge of profiling is also beneficial.
Input Sanitization or Input filtering techniques:
Knowledge on filtering the input data to prevent security hacks is an important skill that any php developer is expected to possess.
Unit testing:
Any php developer or any developer as a matter of fact, has to have excellent unit testing skills just so that the functionality that she/he develops is not full of bugs. Good unit testing helps in reducing the occurrence of bugs in the application and prevents application crashes.
Other skills:
On the whole, a good php developer is also expected to have
a.Good knowledge on the working of HTTP protocol
b.Good knowledge and experience in Apache configurations
c.Good understanding of JavaScript and other scripting languages
d.Excellent understanding of HTML and CSS.


WordPress has evolved from a blogging platform to a full-fledged Content management system that can be used to host and manage large websites. It also provides a variety of plug-ins and extensions that can be incorporated in to the web site with little effort. However, there are some particular skills that a wordpress developer is expected to know.
a.The first and foremost skill that any wordpress developer is expected to know is the knowledge of the WordPress platform and CMS. The developer needs to have excellent grip on the workings of the CMS in order to perform any task that is related to the functionalities of the CMS.
b.Knowledge on the various themes, plug-ins and extensions provided by WordPress CMS is also important.
c.The developer is also expected to have knowledge on HTML, CSS and JavaScript as these are the technologies that are used in the design of the web pages.
d.Good knowledge on PHP and MySQL is also preferred as the WordPress makes use of PHP majorly in the web pages. MySQL is used as the backend.
e.If the developer has gone through the code base of WordPress, then it will be helpful.
f.Apart from these, knowledge on WordPress API’s, AJAX in WordPress and WordPress PHP Classes is also a plus point to have in any WordPress developer. WordPress PHP classes are nothing but the classes that are created by the WordPress users themselves.
