I like programming and learning about stuff I find interesting. Particularly interested in functional programming and typing systems. I have a background in Cognitive Science/Psychology and Mathematics. Sadly halted due to physical and mental health issues arising from getting Covid. Which unfortunately hit me quite hard back on 2020. I'm still dealing with some sequels so I would prefer working from home. I find it fun trying to find insights that cut across disciplines. I tend to favor the "theoretical" side of things. But I also try to get as much hands-on experience as possible. I am writing a blog. Trying to share what I learn, and that others might find useful. I try to focus on the unique things I can bring to the table. Hoping to add value to the life of other developers. I always have a thousand ideas racing through my mind, so I don't have any trouble coming up with ideas on what to write. If any, I have a hard time cutting down on the number of things I want to write about :D On a personal note. I have always been quite solitary and introverted. But I don't think I'm shy. I love videogames and started programming because I wanted to make my own.

Wow ,Jorge! It's a very interesting and informative post. It makes me wonder , how you come up with topics to write in Hashnode when I've been dealing with a Writer's Block since many months 😥 I am always happy to see a lot of Maths stuff being discussed or correlated to programming in your posts. Keep writing 💫💐
