I've built several personal projects to be honest; background jobs, tasks automation, telegram bots to find a house to rent or buy, most of them are kept provate.

The two I'm most proud of are a web analytics that, coincidentally, I've made public today after a few weeks of work:

I developed it for collect data for my personal website and it is working well so far, really happy of it.

The other one is a Google Chrome extension to manage bookmark because I think the default one is a mess and very unpratical to use. I haven't worked on it for a while:
