whoami
hi. i'm a 19-year-old software dev and IT student based in valence, france. i like building resilient apps, exploring system architectures, and contributing to open-source. currently working on my bachelor's degree in computer science (but informatique).
what i build (and sometimes break)
- web & software: kotlin, c#, python, php, js. i mostly play around with vue.js, react, nuxt, and nest.
- mosaic & open source: actively developing mosaic, an open-source app designed for people with dissociative identity disorder (tdi). heavy focus on kotlin, server-sent events (sse), and optimistic ui, because an app should still work when the network dies.
- hardware integration: wrote native android and c# apps to talk directly to serial hardware (esc/pos thermal printers, dispensers) during an internship at ipm france.
- offline-first logic: built and maintained a complete cashless & ticketing system for my high school. handled complex offline states and secure nfc transactions (mifare desfire ev3).
- security & bug bounty: as my write-ups show, i like hunting vulnerabilities in apis and auth flows. i practice responsible disclosure and enjoy reminding companies that client-side validation is just a suggestion.
afk
when i'm not staring at an ide or intercepting requests:
- i do theater and improvisation (huge performing arts nerd).
- i volunteer my time, notably with the secours populaire and solé'val.
