Being an optimistic bubble of enthusiasm since the day I was born did not help with getting some focus in my life. However when building rockets, breathing fire in Romania or chopping wood in France didn't pan out, I decided to give this Software Engineering thing a go. That was over ten years ago and I haven't looked back since.
The last five years at bol.com I've focussed heavily on backend software, which lead me to conclude that we need to find a better way to balance innovation with reliability. Site Reliability Engineering (SRE) just might be that way.
