Taking over the development of existing applications in the Nette or Symfony PHP framework

If you are a medium-sized company with an existing web application programmed in PHP, which runs on its own server and you are looking for a stable and technically competent partner for the further development of your application, then you are my typical customer, because I am a specialist in PHP development, especially in the Nette and Symfony frameworks. And in addition to continuing the development of your application, I am also able to provide management of the Linux server on which the PHP application is run.

My typical customer

My clients are usually medium-sized companies that are looking for a new supplier for the development of their existing application. Most often, these are cases where the original supplier has stopped communicating or communicates poorly, is not flexible enough, or the quality of the delivered work is not sufficient.

Typical problems companies face when developing software

These are typical problems that companies need to solve and therefore look for a reliable supplier to develop their application:

Market and history of applications programmed in PHP

In the corporate sphere, the programming language Java is typically used, which I have worked with for a long time. Small and medium-sized companies typically have applications programmed in PHP.

Historically, the quality of applications and programmers in PHP has been very low. Many applications have been created in PHP and they are still in operation. Such applications are not in good condition, but the functioning of the company depends on these PHP applications.

And this is where the opportunity comes for me - someone who was raised on the robust Java language, standards and good design patterns. Thanks to the fact that the modern programming language PHP supports object-oriented programming, dependency injection and unit tests, I am able to create high quality applications in PHP as well. Last but not least, thanks to the tool PHPStan, which performs static code analysis, it is now possible to ensure the same code quality as that offered by compiled languages.

Technologies I work with

Currently, I most often work on projects that were programmed in PHP, specifically the Nette or Symfony frameworks. These applications use the relational database MySQL or MariaDB or PostgreSQL. If the project also includes other technologies, then I am able to quickly learn and use them.
Thanks to this, my customers will not encounter the situation where I tell them: "the entire application must be rewritten". Which would mean an investment of a large amount of time and therefore money. Moreover, launching a new version of the application will take a long time. And above all, rewriting the entire application on a green field carries great risks.
And thanks to my willingness and ability to take over the development of existing applications, my customers are happy that no major unexpected problems arise and the delivery of new functionality is quick.

Development with AI and AI inside your application

I routinely use AI tools (Cursor, Claude Code) during development. They help most exactly where I work most often - finding my way around a large third-party application, refactoring, writing tests and documentation. For the customer this means shorter delivery times for changes. But I do not let AI decide for me: I review and test the generated code and take responsibility for it. Quality is also guarded by the static analysis tool PHPStan and by automated tests.

The second thing is AI directly inside your application. I connect existing PHP applications to language model APIs - processing and generating texts, working with documents, a chatbot over company data, automatic classification and evaluation of inputs (for example inquiries or e-mails). I always start by looking for where AI brings measurable benefit, and I will openly say when a classic solution is cheaper and more reliable. Part of the design is also what data leaves the company, how much the operation will cost and what happens when the model answers incorrectly.

Complete technical coverage

My customers' applications often run on their own servers (virtual or dedicated) with the operating system Linux. I will take care not only of the development of the application itself, but also of its operating environment - the server. Thanks to this, there is no need to look for a separate server administrator and developer - I can provide both roles (development and server management) myself. This leads to higher efficiency due to less need for internal coordination. Which again saves resources.

Why do customers choose me and not agencies?

Agencies can offer a lot of time capacity and provide unified services. Because an agency hires mostly juniors, it can also be cheaper. However, it must be able to manage the team of juniors so that their work is usable. However, if the customer is looking for customized services, expertise and above all a broad technological overview and business insight, a freelancer is the clear choice for them. Without understanding the customer's business, it is impossible to deliver a quality solution. At the same time, a freelancer offers greater flexibility, which is often necessary in today's rapidly changing business environment.
