👋 Hi, I'm Juan Carlos

I'm an independent developer working on open-source cryptography. My main
project is Quipu — a
post-quantum encryption library that makes quantum-safe cryptography usable by
everyday developers, not just specialists.

What I build

• 🔐 Quipu — hybrid post-quantum encryption & signatures (ML-KEM-1024 +
  X25519, ML-DSA-87 + Ed25519), with one Rust core and first-class bindings for
  Python, Node.js and Go.
• 🧪 Everything is built in the open: AGPL-3.0, 200+ tests, continuous fuzzing,
  reproducible releases on crates.io, PyPI and npm.

Why sponsor me

I maintain Quipu on my own time, and I want to keep it free and independent.
Your sponsorship funds the unglamorous but essential work: an independent
security audit, maintenance across four language ecosystems, interoperability
test vectors, and documentation so more teams can adopt quantum-safe encryption.

Whether it's a coffee or a corporate tier, every contribution goes straight into
keeping this work alive. Thank you for your support. 🙏
