MiNAS

A web file explorer for a NAS, with no VPN and without exposing SMB to the internet.

The problem

Reaching a NAS from outside the office usually means a VPN or opening port 445, a well-known security risk. I wanted to manage files from my phone with neither.

What I built

Python agent that talks to the NAS over SMB with pysmb, designed to open the connection outbound so no ports are exposed.
FastAPI service connecting the interface with the agent.
React and TypeScript PWA to browse folders and upload, download, create, rename, delete and preview images and PDFs.

Challenge

The first plan was a native iOS app, but I don't own a Mac. I built a PWA instead: it runs on the iPhone and let me reuse my web stack.
