Raven Nest MCP
A pentesting toolkit that runs as an MCP server. Wraps 22 security tools including Metasploit Framework (46 MCP endpoints) behind a 6-layer safety architecture, with session-aware context budgeting for local AI models.

Eric Jingryd
Rust Developer · Security tooling and Linux systems
I build secure systems - mostly in Rust, and in TypeScript, Python, and whatever the problem calls for - from JWT authentication and system hardening to desktop applications and CLI tooling. Every project starts with the same question: how do we make this safe by default?

What I've been building
Raven Nest Client
TypeScript MCP client for the Raven Nest pentesting server. JSON-RPC 2.0 over stdio with interactive REPL, tab completion, one-shot CLI, and 110 tests (43 unit, 67 E2E against live Docker targets).
Linux System Hardener
Security automation for Linux. 8 hardening plugins, Ed25519-signed checkpoint rollback, multi-distro support (Ubuntu, Debian, Fedora, RHEL, Arch, openSUSE), 2300+ tests across the workspace. CLI plus Tauri desktop plus Trunk WASM web UI. Published on the AUR.
BitNet Toy
Hand-rolled BitNet b1.58 in pure Rust: tensor with AVX-512/AVX2 SIMD matmul, autograd, ternary quantisation with straight-through estimator, transformer (RMSNorm, RoPE, SwiGLU), training loop, and a CUDA back-end with cuBLAS int8 GEMM on Ada tensor cores. No third-party ML dependencies.
Hyprland Keybind Manager
GTK4 keybinding manager for Hyprland with conflict detection, security validation, and automatic backups. Published on the Arch User Repository (AUR).
Security-First Portfolio
This website: a Rust/Actix-web application with JWT authentication, RBAC, rate limiting, and 12 OWASP security headers. Independently pentested, with the full security posture documented openly.

Let's Build Something
I'm looking for a team that cares about code quality, security, and having a good time doing it. Based in Gothenburg, open to remote - backend, security engineering, or DevSecOps.
