Python Code

My name is Dave. I am a coder by day and trader by night.

I mainly work with Python and Data and I use Open Source tools on Linux.

I believe that anyone can and should learn how to code and should know how the internet and web technologies work.

I use my programming skills to assist me in trading by doing automated backtests and automated trading. This is actually what got me into programming in the first place.


I am a self-taught programmer. Many, many years ago I started running Debian Linux on my desktop and later laptop computers. At that time it was still pretty tricky to get all the hardware to work out of the box. So there was a lot of hacking and scripting involved to get a machine up and running. Then I taught myself to setup webservers and run websites including databases. My first professional IT job was as an eCommerce manager setting up a webshop for a fashion company. I soon realized that I was more of a craftsman than a manager. So I moved on to other jobs where I could actually work on software. I worked in companies using many different stacks and technologies like:

  • HTML
  • CSS
  • Javascript
  • VBScript
  • C#
  • Java
  • Ruby
  • SQL
  • XML
  • XSLT
  • Bash
  • Windows server
  • Linux server
  • Docker
  • Python
  • and many more

So I am pretty all round. You could call me a full stack developer. I also have experience with different frameworks like:

  • Django
  • Pyramid
  • Flask
  • Bootstrap
  • AngularJS
  • EmberJS
  • VueJS

Currently, my main focus is on working on the backend using Python and Postgress. In my day job, I work with a lot of data and I build data ingestion and processing pipelines, APIs, and frontends on a dockerized infrastructure.

Knowledge, experience, and the ability to learn new technologies are most important in being a good developer. Therefore I always work on my knowledge and skills by reading books or doing courses.
