👋 Hey, I'm Nick Angelou 🦀

I scale systems, build secure infrastructure, and chase clean abstractions - usually in Rust 🦀, but not always.

🔬 Projects & Research

🧬 ferroid

Time-sortable (and ordered) ID generators in Rust. Fast, lock-free, and production-ready for distributed systems.

• Designed for high-throughput ID generation with minimal contention
• Built for performance, testability, and extensibility in backend infra

📊 Vizdom

Rust-native diagram-as-code platform for programmatic diagram generation and embedding.

• Full-stack app using leptos, axum, and tokio with SSR and client hydration
• Runs entirely on AWS Lambda with streamed HTTP responses via CloudFront - faster than static S3 for warm requests
• Zero-dependency TypeScript SDK: @vizdom/vizdom-ts-node

🔒 PSI

Co-authored a multi-language asymmetric Private Set Intersection (PSI) library in C++, Rust, Go, Python, JS, and WASM.

• Used in NVIDIA's FLARE SDK
• Applied to privacy-preserving contact tracing and vertical federated ML
• Accepted at NeurIPS 2020 (Privacy-Preserving ML Workshop)

🔐 node-seal

TypeScript bindings for Microsoft SEAL's homomorphic encryption library.

• Compiled with Emscripten + Embind
• Fully documented with a live demo: seal-sandbox
