Hi, I’m Kolja Sam.

I am building web-based MVPs for learners and experts. On this site, you’ll find my portfolio, projects, learnings and writings.

Currently Working On

I am currently working on a prototype for an app to learn spoken Arabic:

Before, I wrote about the idea here:

…and published an even earlier prototype, which is still online as of now:

If you have experience with (or interest in) handling Arabic dialect translation, feel free to reach out!

I’m also a working on a web game where you have to find countries on the world map:

A vending machine company commissioned an app enabling their employees to track ware movements.
I implemented a fullstack web application usable as a mobile app.
It allows user management, login and authentication, digital signatures and complex management of wares and location.
The application was custom-made for the client. If you’re interested in something like this, please contact me via email.

German labor law requires (almost) any business to track their employee’s work time (§17 MiLoG).
Small businesses need a pragmatic, simple solution to be compliant.
To this end, I’ve built a responsive web application allowing employees to track work time, vacations and breaks with no fuss and little cost.
This app ran in production for over a year.
If you’re interested in this product, please email me.

Most often, I reflect about my experience in building digital learning tools:

…and sometimes I write about productivity, organization and note-taking
