About me.

-

I am currently looking for a job in Software Engineering. You can find my CV here.

-

I like to take photos, draw and dabble in some graphic design. You can find this on my Instagram.

-

You can find the code that I write on my GitHub.

- -

If I'm not doing any of this, I'll probably running and/or listening to music on Strava and Spotify.

Specifically this error: + +``` +Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: could not find driver in /path/to/nextcloud/lib/private/DB/Connection.php:139 +``` + +followed by a long, verbose stack trace. + +It took me a decent amount of time to diagnose the exact issue, but eventually I found [this list](https://docs.nextcloud.com/server/20/admin_manual/installation/source_installation.html#prerequisites-for-manual-installation) of required PHP modules in the Nextcloud admin manual. + +Running `php -m` will print out the list of currently installed PHP modules.
