I build local-first, privacy-respecting Android applications and web platforms. My software has no trackers, no ads, and no dependency on someone else's servers: your data stays on your device and under your control.
- Local-first: apps work fully offline, and data lives on the device, not on a central server.
- Privacy by design: no trackers, no ads, no analytics. Cryptography protects people instead of profiling them.
- Open source: code is public and auditable, so trust comes from transparency rather than promises.

Why local-first?
For the past few years I've developed software on limited hardware, moving between a PC with motherboard problems and my phone.
During a repair attempt I lost nearly all of my childhood photos. That experience made the case for local-first software personal: people should truly own their data, without depending on a central server or a cloud platform that can disappear.
I'm currently saving up for a reliable development setup so I can keep building and maintaining open-source tools without interruption.
