David van Erkelens, MSc.

Amsterdam-based full stack software engineer

About me.

I am a passionate software developer who likes to take on challenges. I can dive into a complicated issue for hours and do not give up until I have found a solution. I also like to venture into unexplored territory and I am always open to learning a new programming language or algorithm.

I have broad experience with different tech stacks and programming languages, and can quickly find my way around a new tech stack. I enjoy working in a driven and motivated team and I get a lot of satisfaction from achieving great results with such a team.

In addition to developing software, I also like to be involved in the side activities associated with software development and I therefore like to contribute to sales activities, presentations, job interviews and training courses.

Projects.

AlcoGrip

AlcoGrip is a simple alcohol tracker for iOS, with an accompanying watchOS application. I created this application to try out my skills in Swift and SwiftUI. It integrates with native features like HealthKit, and has been selling steadily on the App Store since I published it.

Advent of Code

In 2022 I participated in the Advent of Code, solving 25 coding challenges in 25 days. As extra challenge, I decided to pick up a new language every day, resulting in 25 challenges completed in 25 languages, fully completing the challenge every day. My repository containing the solutions can be found here.

ADE hackathon

In 2018, I participated in the hackathon associated with the Amsterdam Dance Event, where my team built a project to visualise the popularity of different dance music subgenres over the past 30 years. We secured the runner-up position in this hackathon of 15+ teams, as well as the Armada sponsor price that was awarded.

Skills.

Development

I have extensive experience with programming languages like PHP, C, C++, C#, Go, TypeScript / JavaScript and various other (backend focussed) languages. However, I do not think that a developer should be limited to a specific set of programming languages, and I can always quickly find my way around a new language or framework.

IT

I can work with all major operating systems, and know my way around a terminal. I have experience with cloud services of AWS, as well as on-premise hosting with tools like Docker. I can also work with different SQL and NoSQL based database systems and have intermediate experience with multipe front-end frameworks.

Languages

Dutch (native), English (professional), French (beginner)
