Well, at the last year of my studying in the university (there was 2012 year), I started to work in an international factory.

The factory produced equipment for clean rooms for medical institutions, electronic industry and pharmaceutical factories.

I was design mechanical engineer and I designed nonstandard equipment like boxes of biosafety, pass boxes with UV sterilization and cleaning of air with HEPA and ULPA filters, laminar flow hoods and booth.
