Rust-based Linux EDR agent that watches suspicious processes, file changes, network activity, and persistence attempts using /proc and file integrity monitoring.
TOML rules, JSONL alerts, suspicious ports, reverse-shell-like behavior, cron, systemd, SSH keys, and critical Linux files.AI-powered productivity companion that helps users turn last-minute deadlines into action instead of passive reminders.
React, Vite, Express, SQLite, Gemini API, Daily Signal, Smart Nudge, Break Down, Last Light, Action Lock, Flares, and calendar export.Isolated analysis lab with 5 Windows VMs and 1 Ubuntu monitoring server for controlled malware execution and behavior study.
CAPE Sandbox, Sysmon, Zeek, tcpdump, network telemetry, persistence analysis, and controlled connectivity.Python scanner with banner grabbing, response-latency checks, port behavior analysis, and TLS fingerprinting to identify fake services.
Detects Cowrie, Kippo, Portspoof-like behavior and extracts certificate CN/Issuer fields from unverified SSL contexts.Local-first terminal note-taking tool for Markdown notes with SQLite indexing, tags, links, and full-text search.
Integrated Ollama auto-tagging and semantic embeddings to surface related notes, forgotten ideas, and topic-based search results.open source
document scoping Hardened agent document owner checks across list, read, edit, delete, and suggest flows to prevent cross-user access in multi-user deployments.
admin guard Fixed the companion pairing admin guard import and added regression coverage for the runtime failure.
project Contributed to Odysseus, a self-hosted AI workspace for local-first chat, agents, documents, memory, email, calendar, and model serving.
