Erwin Castricum

Beverwijk, Netherlands กค

My name is Erwin Castricum. An enthusiastic programmer that wants to make a living out of his hobby.

At the moment I am enrolled in the study Applied Computer Science at the Inholland University of Applied sciences. I really enjoy this study because I can enlarge my knowledge about the profession here. Besides my eagerness to learn, I am really ambitious. I always try to grow as much as possible within a company.

In my free time I am a scout leader for kids of ages 11 to 16. I put a lot of energy into this, but I gain a lot of energy from this activity too.

In the rest of my free time I am busy with other ICT related subjects. The Raspberry Pi plays a big role in this.


Software Engineering Intern


Started my internship here in September. I have been working in the Location and Navigation Services team.

September 2018 - February 2019

Software Engineer


Started working here in November and learned a lot about job professional- isation already. My knowledge about Javascript (The framework Vue in par- ticular) also doubled since I started here. We programmed a lot in the language Python (The webframework Pyramid). This is a framework with a pretty steep learning curve.

November 2017 - October 2018


Albert Heijn

Working at Albert Heijn is a fine part time job for a Student. My jobs in the store are stocking the shelves and some Administrative tasks like writing off expired products and ordering new products. Sometimes I have to lead a shift of about 5 people. I really like doing this as it allows me to enhance my leading skills.

University of Applied Sciences Inholland Alkmaar

Bachelor of Applied Computer Sciences
Started with this study in 2015 and knew within a week that this was the branch I wanted to work in for the rest of my life. It's the perfect mix between hardware and software. What I think is beautiful about this branch of work is that you can create a prototype from just an idea in a relatively short period of time. You can create software that communicates with physical objects. I think that is really neat. I started programming in a lot of different languages since i started here. Some where given as courses on school, but I also learned some by myself. The language I use for programming most at school is C. This is because of the microcontrollers we have to program. These are mostly Microchip PIC's.

Kennemer College Beverwijk

General Higher School of Education
Went through this education program in the standard 5 years. I followed the extra subject computer science which laid the foundation for my enthusiasm about programming. It was a nice introduction into the programming world and helped me a lot with making the career choice that brought me to where I am today.

My main interest is to be working at a company where I can use my full skillset. This can be in all branches within the computer engineering domain, as long as it stays challenging. My preference lies with embedded systems though, as this is where I studied for and I find this the most fun to do.
