Building resilient systems, making cloud bills smaller, and keeping the music loud (until you find the mute button).

Things I built and like to show.

Some are work, some are curiosity that turned into a project. You can pause whatever you want to look at more calmly.

Povo Pede

My main personal project right now. We go to the polls every 2 or 4 years and, right after that, end up far from whoever got elected. Povo Pede ("the people ask") is here to shorten that distance: people who live in a city point out what's not OK, vote on what should be fixed first, and the list is public, with the contacts of the politicians in charge right next to it. Votes are anonymous and you get just one per level (city, state and country), so it goes to what you really think is most urgent. Once it's fixed, you get your vote back. No political side, same rules for everyone. I'm building it alone in my spare time, from the code to the infra.

03 / Work

basically: what happens when you put an artist in charge of infrastructure.

I'm an SRE/DevOps Engineer at Somos. My job is to make production systems hold up, get faster and cost less. And if there's one thing I like doing, it's this: grabbing the boring problem nobody wants to pick up, all the way to leaving everything clean for whoever comes next.

I started in customer support, moved to integrations, then DevOps, and spent two and a half years as Cloud Infrastructure Manager running football club membership systems with thousands of users. That's why I get the problem from both sides: the people using it and the people keeping it up.

The result I like telling the most: I cut 80% off the AWS bill while improving system performance. That was thousands of dollars saved and a huge drop in application response times.

Why me, if you needed someone

Cost is a metric

A high cloud bill is a bug to me. Same as high latency. I'll keep digging until I find where the money is leaking.

If it isn't measured, I don't trust it

Observability comes first. That's exactly why this site has a dashboard about itself.

From Terraform to the front end

This site, its infra, my blog and a 3D game set in Niterói: I built all of it. I'm not afraid of any layer.

I take care of what I use

When I find a bug or a wrong doc in software I use, I open the PR. I've had contributions merged at Vercel, Docker, Twelve-Factor, NvChad, Strapi and MDN.

5 years

of DevOps and SRE, from December 2021 until now

I studied Physics at UFF and Information Systems at Unilasalle-RJ. I got the AWS Cloud Practitioner (2022) and Solutions Architect Associate (2023) certifications, and I keep studying on my own: Go and Python for SRE, observability, Elixir.

Niterói, Ilha do Governador and Rio.

The background up there is the view I had from building H, of the physics course at UFF, in Praia Vermelha, Niterói: Rio across the bay, with Sugarloaf in the corner. I spent a lot of time staring at it.

Check the photos below and, right after them, some stats about these places.

Right now, live

Public data, refreshed every 10 minutes by an API I wrote in Go and monitor with Prometheus. It's all in the Observability section.

And right now, how are they?

Public cameras from the three cities, switching every 10 seconds. Here the soundtrack makes room for the radio: CBN Rio, 24-hour news.

I haven't found an open public camera here yet. If you know one, tell me.

06 / Observability

This site measures itself.

I work with observability, so it's only fair that my site shows its own numbers. Visits and speed come from Cloudflare. The city APIs are watched by a Prometheus I run myself on an EC2, with Grafana and Loki next to it.

You are visitor no.

Some lights never fade.

I still miss you, but you remain with me—in the memories I keep and the thoughts I carry every day.

NEXT CHAPTER

An idea for the future: a real shared deploy button. Someone presses it and the music stops for everyone for 15 minutes, just like a production incident. For now it's just an idea.
