in Curitiba, Brazil

Now

Now, and next

The first tab was true the last time I touched this page. The second one has not happened yet. The time above them is not decoration: it is the actual clock in Curitiba, which is where I am while you read this.

What has my weeks. The lighter things at the bottom are true too.

  1. Building

    Nock

    Since June 2026

    B2B lead enrichment for the Brazilian market. Right now I’m structuring the database with our CTO, ahead of our first paying customers. Most of my week that isn’t the internship is this.

    The four of us on a bench in front of the Hotmilk wall at PUCPR, the innovation hub where Nock is being built.

  2. Building

    project_cars

    Since May 2026

    A Python simulator that puts two 3D cars nose to tail and watches the gap between them open or close under aerodynamic drag. Every face of the uploaded mesh is colored by how much air it fights, and the car behind only gets slipstream relief for the part of it that actually fits inside the leader’s wake. I’m on the PySide6 input screens; the physics comes once the navigation holds.

    The simulator running: two red cars on a dark road, one well ahead of the other, with elapsed time, both speeds and the gap between them along the bottom edge.

  3. Building

    Ghosty

    Since August 2026

    An Android app in Kotlin that hides in plain sight: it wears the face of an ordinary app (it can imitate several) and keeps an emergency button underneath. The triggers call the police and open a live voice stream to emergency contacts. Only the front end exists so far, which is where I am.

    Ghosty open in the Android emulator, on the vault screen behind the disguise, with its Kotlin source beside it.

  4. Working

    Bradesco Seguros

    Since November 2025

    Data analyst intern on life insurance and private pension. I build the analytical bases other teams decide from, and I maintain the routine that reaches customers at the moment they’re about to pull their money out.

    The welcome kit that met me on the first day, laid out on a desk: notebook, bottle and card, all in Bradesco Seguros red.

  5. Running

    Builders Club, PUCPR

    Since April 2026

    PUCPR’s developer community meets every week and about fifteen people show up. I speak on APIs and databases. The talks are the easy part; keeping a room of students building on a schedule is the actual work.

  6. Filming

    @sudocarlos

    Since May 2026

    A small YouTube channel I make with care: Python, computer architecture, and what my own path through tech actually looks like. Six videos in, and I still write every one of them out before recording.

    The @sudocarlos channel page, six videos in: two Python course episodes and one on computer architecture.

Things I owe myself, not a roadmap. None of them carries a date, and that is the honest part.

  1. Finishing

    Lynx

    Lynx is my 2D engine in C++ with SDL2 and OpenGL. It builds and runs, then I stopped. I want to study OpenGL properly and rewrite the renderer knowing what the driver is actually doing, instead of whatever made the triangle appear.

    Everything Lynx does so far: its own window open on a flat green field, with a single sprite sitting in the middle of it.

  2. Studying

    Math, again

    It was my favorite part of the course and the first thing to fall off when work and side projects fill the week. Linear algebra and calculus show up in everything I build anyway, so I want the foundation solid instead of good enough.

  3. Shipping

    My first mobile game

    Pixel Car Racer was the game I played to death as a kid. Buy a car, tear it apart, rebuild it, race it. Development stopped and nothing replaced it, so I want my own take: garage, parts, tuning, drag races, pixel art I make myself. Small scope, actually released.

  4. Reading

    The Iliad and the Odyssey

    Both are on my shelf. Neither has been opened. Bought them with real intention and let them sit there, which is somehow worse than never buying them.

    The Penguin Classics slipcase and both volumes, Ilíada and Odisseia, lying on a bed in low light, as untouched as the paragraph admits.

  5. Moving

    My Pokédex, into Pokémon Home

    Bank is shutting down and years of collection are still stuck on the 3DS. This one has a deadline and no excuse.
