I work as a software engineer for a company that, amongst other things, makes mobile phone software. I have worked in several teams working on Android apps. I currently work on processing large amounts of app telemetry data in the cloud, using things like: Spark, Hive, Hadoop AWS, Azure Java, Python, Kotlin, Scala, SQL, and maybe even a little Clojure. To do some of these things, I like to use: GNU/Linux, particularly Arch with i3 A lot of Emacs, a bit of Vim, quite a bit of Intellij git and GitHub good old command line tools, including sed, awk, grep In a previous job, I worked for a company that made mobile phones, working on a smartphone operating system. Don`t look for it. It`s not there anymore. When it was, I did systems programming in C++, working on a number of different operating system components/subsystems. Before that, I had a job as a researcher in a university where I first worked processing data, and learned to program and to make databases and websites. ©
