24/7 monitoring if needed

A problem can easily arise, and you don't know in advance when. This could be, for example, your website or app dropping offline during office hours or that a part of your logistics process stops working at midnight. In these cases you would like to be able to speak to someone directly. As part of my SLA plus and higher, I am available to help outside office hours.

I proactively measure the performance and security of your applications. This is of great importance because of the increasing complexity of web technologies. I monitor the actual availability of your application, any attacks and performance. Timely identification of availability can prevent many issues. To ensure that the web application is actually down, it is verified from various locations around the world whether there is really any down-time. The cause is also determined so that action can be taken quickly.


Speed ​​is an essential part of the user experience of web applications. However, speed cannot be taken for granted. Trends and impact are made transparent by means of extensive reporting. Periodic testing of web applications is essential to ensure that all functionalities work as expected. There is quite a bit involved in maintaining your application that you do not usually think about. I would like to help you with that. Security scans can also be performed on a monthly basis which fully check various essential components for leaks.

How does Deniz Tezcan work?


Introduction & Research

One of the most important but underrated steps. By listening carefully and gathering information, I can offer the solutions that best suit your company. Face-to-face works best, but via Skype or Hangouts e-Meeting is also fine. Before the interview, I ask you to fill in a questionnaire, so I can understand what your company needs even more quickly. After this I will conduct a short research to check the feasibility of your project.

Kennismaken & onderzoek

Think phase

In this phase, we will consider how to give the user the easiest possible process. Giving the user the information he/she is looking for is the basis of every project. After we've gone through the click paths and wireframes we'll come up with a design. I can make this design (or have it made) or you can provide a design yourself. Next, we will check if everything that is required has been incorporated in the designs in one session.


Development & Testing

It's time to code! This is the technical phase, where all hours of thinking, brainstorming and wireframing will come into its own. In this phase, functionalities are delivered in sprints of about 1 to 2 weeks. These will first be tested by me and then I will ask you to test them again. After an MVP is delivered, we schedule a session to test the entire application together from the very beginning.

Bouw & testen

Go live & Support

The best part. After the test phase, the application is delivered and moved from the test environment to the final location. I'm going to teach you how to use your application and update the content and images. Now we're done, aren't we? No - a software process is never finished. Because the world and technology keeps evolving, the applications have to change along with it. Otherwise you run the risk of your application losing its value.
