About Jan
Hi ๐
My name is Jan Meppe and I work as a machine learning engineer at an edtech startup called Snappet.
Before that, I worked as a data science consultant for Cognizant.
My goal (and hope) is that I can use my skills to make a positive impact in the world, making the world a better place.
I wrote some popular tech blog articles
Three popular (>20.000 reads) blogs that I wrote are:
- Regex For Noobs (like me!) - An Illustrated Guide
- How to add a new kernel to your Jupyter Notebook
- How to set Python 3 as default on Mac
I love data-driven decision making
I believe that machine learning is just one expression of data-driven decision making:
- I used data-driven decision making to become one of the best 500 players in Europe in a game called Overwatch (thatโs the 0.0012%th percentile performance)
- I used data-driven decision making to learn how to solve a Rubikโs cube in under 15 seconds
- I used data-driven decision making to reduce a clientโs CI/CD build times by a factor 3x resulting in significant cost savings
I make tiny tutorials about AWS infrastructure
- How to deploy an AWS Lambda serverless function using AWS CloudFormation
- Building a REST API with AWS API Gateway and AWS Lambda in Python
- Automating cloud infrastructure using infrastructure-as-code
I write about things that interest me
I write because I like it and because writing can help people at scale:
- Janmeppe.com hosts 50+ of my blog posts
- Today Jan Learned contains 100+ editions of my now discontinued daily newsletter
- Hacker News featured one of my blog posts on their front page and was read more than 30.000 times.
In the past Iโve built iOS apps
I built an iPhone app that was live on the app store and wrote about what I learned:
- View 3 good things: a gratitude log on the App store
- Simple React Native Redux counter example
- How to add a bottom modal in React Native
I write about how to set up a blog like this
I share what I learn setting up this Jekyll blog with the Minimal Mistakes theme:
- How to remove the excerpt from recent posts in a minimal mistakes blog
- How to change size of blog posts
- How to add a favicon to minimal mistakes
- How to add Latex to Minimal Mistakes
- How to change Jekyll theme to Minimal Mistakes
- How to add a teaser image to minimal mistakes
- How to add a splash image to minimal mistakes
- How to change the font size of the code blocks in minimal mistakes using Github pages

- MPhil in (Advanced) Econometrics from the Tinbergen Institute
- MSc in Econometrics from the University of Amsterdam
- BSc in Econometrics from the University of Amsterdam
