Who am I?

Alexander Chin-Lenn

I worked in intelligence, dealing with radiofrequency waves, demodulation and analysis of signals which inevitably leads to bit analysis and some packet analysis thrown in. During that time I picked up some programming to automate some extremely menial and time-consuming mission tasks that are still in use to this day.

After that, I got moved to a different shop where we had to deal with pattern of life analysis of radars. I made some use of my programming experience again and automated the dataset pulling and analysis of the data to uncover interesting patterns.

Now, I’m searching for my next role practicing cybersecurity, system administration, DevOps and just about anything else that piques my interest.
