Show HN: My OSS P2P file transfer tool for learning Next.js (as a C++ dev)

Hey HN, I'm a C++ algorithms engineer, and today I'd like to share my first full-stack web project: PrivyDrop. This project was born from two ideas: First, I wanted to solve a daily annoyance of mine: I needed a simple, AirDrop-like way to send text, links, or screenshots between my phone and PC. I tried many tools, but they either required me to sign up, had various limitations, or uploaded my data to their servers, which I was never comfortable with. Second, this was a personal experiment. Last year, with all the talk about "AI replacing programmers," I got curious. As a developer with no web background, I wanted to see how long it would take to learn full-stack development from scratch (an area I'm really interested in) and build a complete application, using AI as my primary coding partner and mentor. PrivyDrop is the result of that learning and experiment. It's a peer-to-peer (P2P) file-sharing tool based on WebRTC. Its core principle is that *your da
