Developing your website together

Your website is never finished. This is because the website is actually a running project, so I will continue to support you after going live.

Why is my website never finished?

Although your website is "finished" at some point, it never actually is. The wishes and expectations of your customers change every year and it's good to keep sparring about how we can improve your website. This doesn't mean that we make a new website every year, but it does mean that we regularly launch a new campaign or take a look at SEO optimization.

New features

Because I build your website modularly into my CMS, it's very easy to apply new features. Often it's just a matter of a few clicks because I've already built the same thing once, or it's interesting to add this feature to my CMS and I want to invest in it myself. Overall, it's always worth staying in touch with each other about what's next.

For my clients, I preferably fulfil the role of online partner, proactively thinking along on a strategic level. Translating this into online objectives and then taking responsibility for the implementation. The implementation then consists of the further development of the website or web application and/or the design of new wishes. For this purpose, we agree on a fixed number of hours per month in a Continuous Improvements project.

What exactly is Continuous Improvement

For Continuous Improvements projects I work on an existing online product. Often a project that I developed myself. Before we start, we set up a product backlog. A product backlog is a list of requirements, wishes and bugs. We draw up this list together with the product-owner, who is responsible for the project on the client's side. This gives you control over what will be worked on.

If the product backlog is prioritized I will start the development in sprints of 1 month. It begins with the items that have the highest priority. At the end of the sprint the improvements are released. After finishing the sprint, a new sprint starts again with a new sprint schedule where the most important items are defined; after that, as many items as possible are picked up again.


  • We are continuously working on improving the website or web application.
  • The budget and lead times are fixed
  • There is a lot of room to adjust as a client
  • The tasks can be properly planned, which means less time is required for project management.

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.
