Systems-minded software, built securely.
I build secure systems, privacy-first applications, and production-grade cryptography that withstand real-world adversaries — from classical threats to quantum computing. My work spans end-to-end encryption, anonymous networking, blockchain consensus, and modern full-stack architecture.
I care about mathematically sound security, clean implementation, and collaborating closely enough to turn a strong idea into a battle-tested product.

| Full-stack web | Responsive products built with JavaScript, TypeScript, React, Next.js, and RESTful APIs. |
| Cryptography & security | Traditional RSA, ECC/ECDSA, AES-256. Post-quantum Kyber, Falcon-512, Dilithium, NTRU. Applied ECIES, HKDF, ChaCha20-Poly1305 for production protocols. |
| Blockchain & P2P | Core blockchain architecture — consensus, P2P networking, Kademlia DHT, JSON-RPC/gRPC APIs. Quantum-resistant chains with lattice-based signatures. |
| Secure systems | Anonymous messaging over Tor hidden services, end-to-end encrypted protocols, real-time sockets, and privacy-first data pipelines. |
| Cloud delivery | Production infrastructure and deployments across Linux, Oracle Cloud, AWS, and Azure with Nginx and process management. |
| Mobile development | Cross-platform mobile applications built with React Native and Flutter for iOS and Android. |
