Advent of Code 2019
Catawiki raffle
Congratulations to Shicheng Rao!

Thank you to everyone who participated, you made this a really fun challenge... and we hope you'll join us again next year!

Catawiki is happy to be sponsoring Advent of Code 2019.

Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. Every day from 1st to 25th December, there are two challenges. For each challenge you solve, you’ll be rewarded with 1 star.

We’ve set up a few private leaderboards for this challenge, where you can compete and hopefully win a prize through our raffle!

The skills required for this challenge are similar to those used by our Tech team at Catawiki to solve some complex development tasks that result from our continually increasing numbers of sellers and buyers (14 million monthly visitors and rising!). We’ve already implemented localisations for various European countries and we’ll be expanding even further, outside of Europe, in the near future.
