Papotech Editor

Podcast editing automation with Python

A command-line tool that takes the recordings from two microphones and returns synced audio with long pauses shortened, a transcript and a list of spots to review. It came out of my own editing routine for the Papotech podcast.

Sync based on detecting hand claps (RMS energy and peak detection)

ManiProtein

Landing page for an innovation project

A website presenting ManiProtein, a plant-based protein made from cassava and the winning project at Inovathon FIMAN 2025. I built the landing page; the product idea and the pitch were team work.

Ecos do Olimpo

An indie game built from many connected systems

A 2D top-down game I'm developing solo in GameMaker: gathering, crafting, grid-based building, farming, automation and offerings to the gods, all tied into one progression loop. Alpha 0.1.2 is public; the Demeter Update is in development.

Three alpha releases shipped in one week (0.1 to 0.1.2)

Supporting student retention, from early signal to real support

A prototype built as a team at the WorkInTech 2026 Hackathon for the school dropout challenge. Instead of only flagging who is at risk, it helps a school understand the barrier behind the absences and route the case to whoever can solve it. Demo with fictional data.

About me

I learn by building.

I study Software Engineering (on campus) and Digital Games (online) at UniCesumar in Brazil. I started programming at around 15, making games in GameMaker Studio 2, and I've been turning what I learn into shipped projects ever since.

Today I work across web development, Python automation and games: I built the ManiProtein landing page, a tool that automates podcast editing and the public alpha of Ecos do Olimpo, which evolved with feedback from players. I also create content as FZF Dev (formerly FZF Productions): devlogs, tutorials and game jams.

Hackathons taught me how to work in a team on a tight deadline: validate an idea, split the work and pitch the solution to a panel of judges. Now I'm looking for a software development internship, ideally in front-end, where I can learn from a team and contribute to real products.
