Mechanic
I love to fix engines that don't start or run rough. Even if a part is broken I can rebuild or repair (instead of replace) it.
Electronic
If a kitchen machine, lamp, radio, tv - simply every kind of electronic device is not working anymore, my spirit wakes up and I'm trying to fix it.
Computer
If computers or laptops are running slow or don't even work I can fix parts of them, reset them and make them fast like new. (even faster with an installed SSD)
