How did you get into software?

Looking back, I was closer to it than I remembered throughout my life. I had a small glimpse of what programming could be like when I was in middle school, there was a robotics competition in some schools in my area and I got the chance to be part of my school's team. Well, things went horribly wrong, the poor robot barely moved, and I froze as well. Later on I had a tumblr where I carefully selected my HTML structure and CSS themes from Pastebin.

Fast forward a few years and I enrolled in an IT technician course during my sophomore year of high school (for reasons that had nothing to do with IT, I just wanted to be more independent as a teenager). I already knew my way around a computer, so I figured I would be at least decent at programming, but as the class progressed, I discovered that I was actually better at it than I initially thought. So much so that after I graduated, one of my teachers decided to hire me to work with him at a SaaS company he co-founded.

What does your desktop/home screen look like?

The wallpaper changes from time to time, but it's usually something I can look at in the dark without burning my eyes

Why are you at Resend?

As a developer, I feel most fulfilled when I'm working on something that's very useful and makes people's lives easier. Not only is Resend focused on that, but I can also see myself on the customer side, something I was not used to as an employee. But besides the product, I can say that the philosophy resonated a lot with me and what I want for my career.

Where do you find #inspiration?

I am often inspired by people who are good at a craft (or who share their journey to becoming good). I am also very inspired by things that are so well done that I have a hard time understanding how it was built and how someone even initiated it. So if I had to sum it up, people who do things and things that are well done are what inspire me the most

If you weren't programming, what would you be doing?

There is a very high chance that I would be doing something related to design and illustration. There is a part of me that likes the idea of teaching, maybe sometime in the future

Favorite tool?

When thinking of something I use both for work and non-work stuff: Notion has been very much my right-arm in terms of taking notes

But solely for software development: I love Zshell and VS Code (I have been trying Trae recently and it’s pretty interesting)

Favorite hotkey?

I don’t think I would have a career if it wasn’t for ctrl+z (shout out to rest of the family: ctrl+c, ctrl+x, ctrl+v, life is better with them)

Favorite place to visit?

Wherever I'm with my family and loved ones, it doesn't take long to become a favorite, so it's very hard to pick one. When I'm alone, I'm probably trying to find a new restaurant to eat at, so I'll say: Spot, near Av. Paulista, it has some amazing food, good drinks and a profiterole to die for

Advice for ambitious software engineers?

I think I will add to the chorus of advice from other colleagues here: you need to stay curious and keep learning (and trust me: re-learning as well) all. the. time.

Ask questions - try to search for information before asking, but when in doubt: ask

Also, sometimes you won’t be the biggest fish in the pond and if you actually want to grow that may be a pretty good direction
