I've made a lot of small projects, some of them are open source, others are used only by me and other people I work with. One of them is minupdater, a simple updater system for desktop applications. It's written in PHP, but the code sucks and it can't be used by anyone rather than me. Another cool project is bracecker, that we use daily. It's an uptime checker that notifies you through datadog if some of your services go offline and calculates uptime for you, too! I love Datadog, so I've also made ddd and dtg, two small scripts that report datadog events to multiple Discord channels and Telegram, respectively. Another cool project is icebirb, a backup and data sync system we use for Ripple. Oh and I was forgetting sshsas, a 2FA authentication system for SSH that we use in all of our servers as an additional security level! You can find most of my minor projects on my GitHub.
Some years ago, when I didn't know how to program properly, I made some games using GameMaker: Studio 1.x and GML, GameMaker's Scripting Language. It was a very fun learning experience, I've made a lot of prototypes that I never released and I've entered the GMCJam too! My biggest project (which I didn't finish) was Zombie Warfare. I also had a ton of fun making Tower's Soul Is You, my entry for the GMCJam #15, a competition where you have to make a game in 72 hours following a particular theme.
