Backup & recovery engine for Docker Compose. Coordinates Postgres / MySQL / Redis dumps with filesystem snapshots into one consistent point-in-time backup. Client-side AES-256-GCM — the storage provider never sees a raw byte. Streams in 32 KB chunks, so memory stays flat at any size. Live progress over Server-Sent Events; every backup is auto-verified — if it can't be decrypted, it doesn't count.

AI legal assistant for Dutch law. Full-stack workspace built solo (~120K lines).
