Currently I am mostly developing things with C++, Java, or Bash. As my main desktop OS is based on Linux I always try to build things crossplatform. On the mobile side my main focus is on Android. I am also working a lot on servers and development services, here I use serveral languages/frameworks mostly combined with Bash scripts. For embedded/IOT development I mostly work with Atmel or ARM based platforms (Arduino, AVR, Raspberry Pi, i.MX, ..).

Here are some more platforms, frameworks, services and technologies I used for development:
