Full Stack Developer & Privacy Engineer — building secure, scalable mobile & backend systems with a strong focus on encryption, usability & zero-compromise architecture.
🔭 Currently
- Building Erebos — a privacy-first anonymizing network with hybrid post-quantum cryptography (X25519 + ML-KEM-1024), adaptive cover traffic, reproducible builds, and a published threat model
- Working on Erebos Browser — an I2P browser (Firefox ESR 128 based) with a live governance UI backed by the Erebos Network daemon
- Consulting on PQC migration for end-to-end encrypted apps (Kyber · Dilithium · X3DH · Double Ratchet)
🌱 Currently learning
- Advanced state management — Riverpod · BLoC
- Secure DevOps — reproducible builds · supply-chain verification · GitHub Actions
- Browser engine hardening — fingerprint uniformity vs. randomization
Flutter-first, with native SwiftUI when it matters.
Typed end-to-end, containerized, automated.
Battle-tested foundations.
Ready for the next decade of threats.
