My Projects
I build software because I fell in love with UI & UX many years ago. I see them as a creative outlet, but also as small pieces of care we put out into the world.
For me, it’s not about reaching the biggest audience or maximizing revenue (that’s what my day job is for). Instead, I focus on building things that feel useful, considered, and that I can genuinely stand behind over time.
Jingles da República
A festival site for songs about the state of Brazilian politics.
On September 4, 2026, Coletivo Zero and Medo e Delírio launched Jingles da República, a jingle festival. Anyone can submit a song of at least 30 seconds about the political state of Brazil and compete for cash prizes.
I built the site with Swift, Vapor, and a lot of help from Claude. I picked the stack, decided what looked good, and set up hosting on Linode. Claude wrote most of the code.
Submissions go through email confirmation and are screened for AI-generated audio with Sightengine, so the contest stays about real songs. We also built load balancing and worked through server memory concerns before launch.
What surprised me is that it actually worked. I expected months of work and it took weeks. Now it's live, and I'm the only one maintaining it, from hosting to observability.
Role: Developer, infrastructure, QA, and sole maintainer
Integrations: Email delivery, Sightengine (AI-content detection)
Status: Live, submissions closed on Sep 27. Jury period until Oct 3rd. Festival is on October 11.
Dùn
A private space for personal links that don't belong everywhere.
Dùn is a utility app designed to help separate personal links from shared contexts. It’s for things you care about, but don’t want surfacing during a work meeting, screen share, or when handing your phone to a friend.
The app was born out of a very specific anxiety: having personal links from my Safari Reading List unexpectedly appear on my work laptop. While Face ID exists for passwords and sensitive data, there wasn’t a clear, intentional place for links that simply require a different context.
Dùn is local-first and intentionally boring. It’s a place to store links, add light organization through notes and tags, and find them again when you need them, nothing more. It’s not Pocket 2.0 and it’s not a password manager. It’s its own thing, built around the idea of separation between what you’re ready to share and what you prefer to keep private.

Medo e Delírio
A companion app for a Brazilian political podcast.
I started Medo e Delírio in May 2022 as a way to channel frustration, both with my job at the time and with the political landscape in Brazil. The app is a companion to the podcast of the same name and centers around short sound bites that users can share as humorous replies in conversations.
What began as a small side project grew into something much bigger, with thousands of monthly active users and a very vocal, engaged community. Maintaining and evolving the app over time has been a lesson in long-term ownership, listening to users, and shipping changes that real people immediately notice and care about.
It remains one of the projects I’m most proud of.

At their core, these things are about making space: for humor, for privacy, for context. I’m interested in how software fits into real lives, and how small, thoughtful decisions can reduce friction rather than add to it.
The apps specially are ongoing conversations more than finished statements. If any of this resonates, I’m always happy to talk, about product, design, or the small decisions that shape how software fits into our lives.
