Hello, I'm jlelse.

Student & Developer & Blogger

About me

If I were to describe myself, I would do it like this:

I am 18, a technical person (some would call me a geek), passionate about writing program code and blog articles (on all sorts of subjects). But I don't just sit in front of the computer, I also do sports (rescue swimming) and meet other people.

I have several self-developed apps for Android, many of which can be found on Google Play and websites. A few years ago, I launched a publication with articles about Android on Medium, which now has more than 30,000 subscribers and several hundred thousand monthly visitors and so helps a lot of developers when they are searching for ways to improve their work.
