For the past year, I've been working on an online scavenger hunt. It features many tech related challenges on various topics (web, protocols, crypto, stegano, ...).

This is the project as a whole, but I had to work on many sub-project to bring it to life, out of which:

• a Pokemon game (assembly)
• an online scoreboard (go)
• an encryption tool (go)
• a crypto hashing tool (go)
• a cli interface (C)
• many deployment shell scripts
• ... much more

What I love about this project is that it touches many different topics. I had to setup reverse proxies, complex firewall rules, VPNs, abuse the TCP/IP stack, ... I could also work on very useless but fun topics, like creating a tool that answers to ICMPv6 traceroute packets to insert fake hops between the requester and the destination. I'm now close to releasing it, and I wonder what I'll do when this is over...
