Selected projects

pq-boringtun Rust · cryptography · networking
Hybrid post-quantum key exchange for WireGuard: ML-KEM-768 alongside X25519 in the Noise IK handshake, built on Cloudflare’s BoringTun. The first FIPS 203-compliant hybrid WireGuard on a production Rust codebase, benchmarked on Apple M4 and Raspberry Pi 5. My BSc thesis.
-
Supernova Swift 6 · Metal · Core Audio
A live-wallpaper engine for macOS. Renders looping video, Shadertoy-style GLSL shaders transpiled to Metal, and sandboxed web bundles behind desktop icons — with audio, cursor, and motion reactivity, per-display assignment, and smart playlists.
-
Atlas — RAG platform for BluePlan Python · FastAPI · Qdrant · React
Retrieval-augmented chat over uploaded technical documents: hybrid dense, sparse, and image retrieval fused with RRF, reranked, with verbatim citations pinned to the source PDF. Multi-tenant, multilingual, closed-source, and in daily production use.
-
eBPF network analysis eBPF · C · Rust · Python
Network traffic classification for QUIC protocols using eBPF — inspecting encrypted flows at the kernel boundary.
-
nvim-search-and-replace Lua · Neovim · ripgrep
Project-wide search and replace for Neovim — async streaming ripgrep search, live before/after preview, selective replacement, and its own undo/redo stack. No quickfix list, no sed. Neovim, btw.
-
GeoDraw React · TLDraw · LLM APIs
An AI-powered canvas for sketching and wireframing apps — natural language in, accurate real-time design output on the canvas.
