Realtime-Notes Application

A full-stack collaborative notes platform with real-time sync and enterprise-grade security

Full Stack Developer3 monthsSolo project

Next.jsSocket.ioNode.jsMongoDBJWT

1 of 5 sections open

Existing note-taking apps lacked real-time collaboration or required expensive subscriptions. Users needed a solution that combined the simplicity of basic note apps with instant sync across devices — without compromising on security.

Sync delays of 5-30 seconds in competing apps

No end-to-end authentication in free alternatives

No searchable dashboard for quick note retrieval

Multi-AIUnified chat interface

AI Chat Fusion Platform

A unified interface to interact with multiple AI models simultaneously

Full Stack Developer2 monthsSolo project

ReactExpressMongoDBTailwindNode.js

1 of 5 sections open

Users who wanted to compare AI responses had to switch between multiple tabs, copy-paste prompts, and manually track conversations. There was no single interface to query multiple AI models and compare their outputs side-by-side.

Context switching between 3-5 AI tabs per query

Copy-pasting same prompt wastes 30+ seconds each time

No unified history — conversations scattered across platforms
