Featured Work

Distributed ledger systems, hardware-level cryptography, and inference pipelines built for sub-second latency.

Aureus: Sovereign Edge Node

Local-first financial ledger implementing CRDT-based conflict resolution for offline transaction signing. Stream-based state management via BLoC pattern with Isolate spawning for AES-256-GCM encryption of ledger entries. Achieves sub-200ms sync latency through delta compression and optimistic UI reconciliation against serverless Cloud Functions.

Multi-Chain Vault

Non-custodial EVM/Hedera vault with Dart FFI bindings to libsecp256k1 for raw transaction signing. Zero private key exposure via memory-isolated cryptographic operations. Implements EIP-1559 gas estimation and deterministic nonce management for atomic cross-chain swaps.

Cryptographic Identity Layer

Hardware-level KYC via ISO/IEC 14443 NFC protocol for ICAO 9303 passport chip extraction. BAC/PACE authenticated channel establishment with SHA-256 hash verification against MRZ-derived keys. Liveness detection through temporal frame differencing and infrared depth mapping.

Context-Aware RAG Engine

Retrieval-augmented generation pipeline with HNSW-indexed vector store for O(log n) semantic search. Implements sliding window context management with 8K token budgeting and re-ranking via cross-encoder scoring. Supports local LLM inference through GGUF quantization for on-device privacy.
