Project Description Tech Stack Link
ColabCode Real-time collaborative IDE for technical interviews and pair programming. Decoupled React frontend (Vercel) talking to a sandboxed Node.js/Socket.io backend (AWS EC2). Yjs CRDT editor with per-file isolation and zero-data-loss late-joiner sync. Docker-sandboxed execution engine (JS/Python/C++/Bash) - network disabled, 128MB memory cap, hard timeout kill. WebSockets scaled via Redis pub/sub with room presence tracking. TypeScript Socket.io Redis Docker WebRTC AWS EC2 Live Β· GitHub
SecondBrain Full-stack AI-powered personal knowledge manager - an external memory for videos, tweets, PDFs, links, and notes. Full RAG pipeline built from scratch (embed β†’ vector search β†’ context injection β†’ inference, no framework abstraction). Async fire-and-forget save flow cut perceived latency from 3–5s to near-instant. Fixed a production cross-domain auth bug (JWT cookie sameSite config). Entire AI/infra stack runs at $0 cost, no OpenAI dependency. React MongoDB Atlas Jina AI Groq JWT Live Β· GitHub
CodeScale Full-stack coding judge platform with AI-guided DSA practice. Server-side execution engine via child_process with sandboxed isolation, 9s timeout, and safe temp files. MongoDB schema (Mongoose) for users, problems, submissions, and per-difficulty scoring. JWT auth with HTTP-only cookies, bcrypt hashing, Zod validation, and admin role-based access. Integrated Groq (LLaMA 3.1 8B) for AI guidance plus a Dry Run Canvas with react-sketch-canvas. Node.js Express MongoDB Groq JWT Live Β· GitHub
GlassyUI-Components - Open Source Fixed UI theme inconsistencies across 29 pages by building a shared PageShell layout for a unified visual identity across the library. React TypeScript Open Source Repo
ReactPlay - Open Source Added reusable Skeleton UI components to improve loading feedback and overall responsiveness across the platform. React Open Source Repo
