This list contains a selection of the projects I have worked on and I am currently working on. The most recent project is on top.

Microblogging Platform

Private Project - 2019

Another side project. I believe that many social networks share too much information and encourage posting of private details of everyone’s lives. On the other side these websites allow users to keep a lot of precious memories and moments. I am building writic to provide a place for this kind of information: Memories that I want to keep, either in written form or as photos, but not necessarily share with the rest of the world.

Air Quality Index (AQI) Notifier

Private Project - 2018

A side project based on Python/Django, the AirNow, Telegram and Twilio API. This tool allows to enter phone numbers or to self register via a telegram bot to receive updates about the air quality in your zip code once the quality significantly changes. I built this service to be informed about sudden changes of air quality after the massive wildfires in California in 2017 and 2018. In the most recent months, I have added more features:

  • Notification Threshold: This keeps you informed whenever the air quality index rises above a certain individual threshold. This is mostly to avoid spamming and only show really important changes in pollution.
  • Monitor air quality and temperature at home: Check it out here

Base62 Decoder/Encoder

Private Project - 2017

Encoder/Decoder for numbers into base62. These are string which consist only of A-Za-z0-9-_ and are compatible with any URL scheme while providing higher density than base 10 or base 16 numbers.

Peak Flow Log

Private Project - 2014

Peak Flow Log is an iOS App to keep track of different Peak Flow values for asthma patients over time. Individual graphical indicators help to determine the current health condition.

There exists also a so called “Plus-Mode” which removes the advertisements and provides an export function as well as more detailed statistics. This app is no longer available on the App Store.
