Proud of my career

Hike One, is a leading digital design agency. A playful and talented team consisting of over 60 design specialists operating from Amsterdam, Rotterdam, and Eindhoven. Constantly figuring out how to do things better. And faster, cooler, and easier.

I started with an internship and when I finished it, I could stay to work as an interaction designer on innovative products for all kinds of clients and all types of screens. Using a variety of methods to help the client, but most importantly, to help the users.

Let's build IT is a full service web company that helps to design print and websites and also build them. It's a small team of 16 happy designers and developers based in Hoorn with clients in all kinds of sectors. They have a specialism in financial websites.

In 2006 I started with an internship and after a few months I started as a webdesigner, making designs for clients. I liked designing the Let's Build IT client area the most. Making it easier for clients to edit their website and let users fill in forms the fastest way.

Clients I worked for

I did a design sprint at the ANWB to give the company some ideas to improve the users search experience.

Made the interaction design for a system used by professional sellers on Ebay platforms like Marktplaats and

My first job at Hike One was to create a new game for Greenpeace. The game should inform users, but also be fun and aimed at receiving donations.

For the KPN project we made designs for one of the first versions of the mobile app. The question we focused on: How do you visually show bundles?

One of the more recent projects is the entire digital world of the NPO. I made designs for the current apps and websites.

I thoroughly tested the website of Philips, which consists of many small components.

For the Rabobank I made designs for mostly internal tools like an intranet and internal mobile websites.

Worked with a big team on the interface of the new Horizon box (release 2019). A tv box for every user of Ziggo for TV on Demand.


Intelligence Studies

The minor in intelligence studies discusses the structure, working method and (qualitative and quantitative) research methods of intelligence and security services as they originated in the second half of the twentieth century. It also focuses on cryptography, for services that played an important role on the international stage during the Cold War, such as the KGB and the CIA, and for more recent phenomena such as Cyber Intelligence.

Communication and Media Design

The study Communication and Media Design (CMD) covers strategy, design and technology. During this study I learned to think and act like a designer. In addition to learning ‘design’, I also learned ‘creation’, ‘research’, ‘project management’ and ‘consultancy’.

  • Amsterdam University of Applied Sciences
  • 2008 - 2014

Media Design

I learned to apply design to various publications. Some examples are: posters, (digital) magazines, billboards, websites and apps. I also learned how the media world works, what the role of the designer is and how media are made.

I Used Phishing To Get My Colleagues’ Passwords. This Is What I Did.

Feb 3, 2017 - Sebastian Conijn

Did you know that 1 out of 3 people opens a phishing email, and if it’s a ‘personal’ phishing mail, the numbers are even higher? The American Democrats, Sony, and users of Gmail have all been victims of phishing. It’s a problem that’s getting bigger, and the success stories of hackers are growing every day. As designer at Hike One, I felt the urge to check if my colleagues were aware of the risks of phishing, by trying to collect their passwords.
