My name is Daniel Engvall, and living in Sweden 🇸🇪 together with the rest of my family. I use GitHub for my personal projects that include code and documentation, the majority of which is written in Python 🐍 together with technologies such as Dockers, which is and has been one of my primary go-to programming languages after I've been exposed to other languages such as Basic, C++, Perl, Pascal, and PHP, none of them fell into my true taste. While I developed quite sophisticated solutions using Bash that eventually got outgrown and I pursued a productive, dynamic, and full spectrum language to run well from anything from microcontrollers and embedded systems (anyone ever had a Dreambox 📺..?) .. GUI apps, even mobile apps, web-frontend development (e.g. PyScript) and statistical analysis to the scalable server application (FastAPI to name one of many). So, I have tried using Python for the most versatile purposes. 😅👍

Also, home automation and microcontrollers (where) some of my projects found here include wiring schemes. Outside of my personal space, I've also used Groovy/Java and learned a lot from doing that.

A more recent growing passion for better understanding and writing more maintainable software using good practices and software design. Also had a strong devotion to documenting ideas and thoughts around those projects 🫶

Some facts about the current content are found on my GitHub - but feel free to check them out in detail over here:

• During the past 11 years have written 45027 lines of code across 42 projects collected here.
• Out of those projects written here, currently the largest ones are written with around 5k lines of code, currently at the top being iot_fan_controller, tasks_collector and otis_service

This has been dynamically updated on 2025-08-10 02:09 with the help of Python and GitHub Actions.
