Fast by default. Analytical, algorithmic thinking and the experience of over 20 years of programming with PHP deliver well thought-out and optimized PHP code for your project.
When it comes to the storage/processing of data in a relational database, I can rely on my many years of experience as a programmer.
I develop a data model already with the application in mind, so tables and links are created that can be processed perfectly in the PHP software.
I can develop an appropriate and advanced database model for any application, optimize an existing database, make existing SQL queries more efficient, and even develop complex SQL queries.
The focus is on a high-performance data model and a reduction of SQL queries for more free processes and a minimum response time.
The so-called response time of a website often has to do with programming on the web server. If too many processes are running, the response behaviour of the web server is delayed and the positive experience of the visitors dwindles.
I work on performance optimization, both in the backend (PHP, .htaccess and SQL queries) and in the frontend (HTML, CSS, JS).
In the foreground is an application that literally doesn't lose any time.
Finding a solution or an error quickly is just as much in my blood as keeping a big project in detail and all consequence in mind.
I solve small tasks efficiently, can be a fullstack developer, implement a project completely or be part of a techteam.
Onlineshops, tracking systems, backend administrations, APIs, monitoring systems, frameworks and much more I have already designed and developed. Numerous developments have received awards at innovation prizes. Basically, there are not many business processes that cannot be displayed online.
As an entrepreneur and software architect I am interested in the analysis and optimization of business processes up to digitalization and web-based automation. The focus is always on profitability from the entrepreneur's point of view.

In my time as a retailer with a view to process optimization, I noticed a lot of things from colleagues, among others, which I pass on via Optee in the form of interactive consulting. Optee was awarded right away in the category online consulting.
Features:
With Optee I analyze the click path and can generate mathematical evaluations in dependencies as well as point out correlations resulting from the given answers.
Good Vintage is my second own online shop with traditional decorative and utility products.
Features:
The online shop is based on my own shop technology, but has been extended by variants and special configurations.
I look back on many exciting and successful projects. In 2001 I designed and developed Vorlagen.de. At that time, Vorlagen.de was a pioneer in terms of paid content and for a long time belonged to the most successful e-commerce sites in Germany. Vorlagen.de was sold in 2012.
As early as 1995 I developed tracking systems for air and sea freight, connected online shops to merchandise management software, brought the editorial system of a large daily newspaper online, developed content management systems, wrote monitoring systems for startups and much more.
