Back-end development with PHP

As a Full-stack Web Developer, my expertise lies in creating robust and customizable Web Applications using PHP and various frameworks, with a preference for Symfony. I have experience utilising various SQL databases, such as MySQL, MariaDB, and PostgreSQL, and utilising ORM libraries like Doctrine to interact with them.

PHP Developer

I have been working with PHP for over 15 years, starting from version 4.3. Throughout this time, PHP has undergone significant improvements and remains one of the most prominent languages in web development.

Adopting PHP offers several business advantages such as cost-effectiveness in both development and deployment, and access to a vast and active community of developers to aid in resolving technical issues.

Key skills as a web developer: Clean Code and Strong Teamwork

I believe that being an outstanding programmer involves more than just technical proficiency. As technologies are constantly changing, it's important to also focus on other key aspects of software development.

Strong teamwork and communication skills are crucial in software projects, as they serve to enhance collaboration and meet the needs of customers.

Writing clean code is also crucial because it facilitates understanding and maintenance of the software by others, and it make it easy to update and troubleshoot, which is particularly important in software development.

I specialise in building custom web solutions, including payment systems, chatbots, survey builders, user-generated content areas, and booking systems, to name a few.
