summary
about me:
- native developer focused on mobile reverse-engineering, mainly Android and iOS.
- domains: Android/iOS reversing, IL2CPP workflows, and game tooling/modding pipelines.
- current focus: learning cool stuff while studying at UC3M and contributing through student tech groups.
- fun fact: due to the region i live in + my family, i'm proeficient at 4 (irl) languages.
stuff i really like:
linux- homelabs
- navidrome
- TUI apps
- FPGA emulation
- skiing
- Android rooting
- iOS jailbreaking
Steam
opinions:
show/hide (warn: politics)
- i advocate a lot for FOSS, transparent code is vital for our privacy/safety
- anyone ideally should own the tech they purchase, avoid tech that cant be unlocked
- ai is amazing if used properly, but vibe-coding is horrible (unless its at frontend)
- privacy is a human right, no matter if we "don't have anything to hide"
- politics should NOT have a place in the FOSS community, it's like mixing water and oil

about this site
tech stack: Static HTML, CSS, JavaScript (vanilla). Framework: WebTUI with Catppuccin Mocha theme.
live data: GitHub API for real-time repo stats. Keyboard-driven TUI navigation with vim-style bindings.
ai usage: i dont like AI for my main work, especially on native code, i feel like it makes me lose more time than what it gains, that being said, this website was made mostly by AI, since i don't care about frontend, and probably never will.
tldr: vibecoded lol
