A few details about me

Hello and welcome! I am Christian. My passion is making things in general, and software in particular. I have an insatiable drive to be a defining part of projects which improve the world's quality of life.


I specialize - and have accumulated considerable experience - in software engineering, particularly the kind which sits closer to the hardware level (embedded apps).

I was born and educated in Romania where, besides engineering, I received additional training in arts, medicine, photography, military psychology, and chess. I started writing software at the age of 12, during the Romanian revolution against the communist regime.

In my work, I strive to achieve the quality that I'd personally expect from a product that I use in my everyday life - and I'm picky with those.

My ultimate professional goal is to reach a convergence point where all the values of my ideal work environment meet: exciting work on a challenging and useful project, an extraordinary team, and generous compensation. I believe in traditional work relationships, based on mutual respect and trust, where you offer your best effort and unrestrained focus, and receive the company's best in return - good life balance, compensation, and career advance opportunities. I'm a big advocate of telecommuting, and have had outstanding results with it on numerous occasions.

I speak and write Romanian, English, and German at native speaker level, and have successfully completed commercial projects in all three.

In my private life, I'm happily married and have children. I enjoy having variety in my non-engineering activities: photography, woodworking, drawing, occasional cooking and baking, bike riding, home improvement and flying RC models. I love playing pool, ping pong, table football, and soccer. Whenever possible, I like to travel and reconnect with my origins in Romania and Germany.
