Hi, I'm Paulo Köch. I'm a software engineer, and I live in Porto, Portugal.
My personal web presence is probably best described at keybase.io. My email is first name, period, last name (no diacritics), at gmail.com.
For my professional info, check out my LinkedIn profile.
There was a blog here, but I got tired of updating it and not writing enough. You can use the Internet Archive if you want to check it out.
