I am an Android - iOT full stack specialist, writing native code, firmware, drivers, etc. It is important for me to work on things that matter (for a fair society). Currently, I am the main developer and co-founder of citizen science project CanAir.IO. With this Initiative many people will be able to fight for air quality rights in many countries with these problems. CanAirIO uses mobile and fixed sensors to measure air quality with cell phones and low-cost technology. Right now we have a community on many places of the world with fixed stations. For this reason, I'm working in a better mobile solution: CanAirIO Bike. Thanks for supporting my work.
