Designing scalable systemsand intelligent backend infrastructure.

Problem

Searching through large chat histories is slow and inefficient, making it difficult to find relevant messages quickly when dealing with history-heavy workflows.

Solution

A full-stack application with a high-performance C++ backend using inverted indexing for lightning-fast text search, paired with a modern React frontend for instant, highlighted results.

Architecture highlight

React Frontend -> REST API -> C++ Backend (Inverted Index) -> Message Database

Impact

Reduced search latency from naive string matching to microsecond-level retrieval, enabling users to instantly find messages in massive chat histories with responsive, highlighted results.

Problem

GenZ listeners want to share, discover, and jam with friends in real-time, but existing music apps lack seamless social features, collaborative listening, and peer-to-peer music discovery.

A full-stack music streaming and social platform enabling users to upload songs, create playlists, like tracks, add friends, sync playback in real-time jam sessions, and share music with an intuitive glassmorphism UI.

Architecture highlight

React + Vite Frontend (Tailwind CSS) -> Express.js Backend (Node.js) -> MongoDB Atlas + Socket.IO -> Cloudinary Cloud Storage

Impact

Empowers GenZ to build a connected music community with real-time collaborative listening (jam sessions), instant music discovery through friend recommendations, and frictionless audio/cover uploads with cloud optimization.
