Final-year CSE @ Bengaluru  ·  Full-Stack & Real-Time Systems  ·  Open to SWE Roles (2025)

I build real-time, production-ready systems — collaborative editors, sync engines, and developer tools that actually work under load. My focus is on correctness, latency, and auth done right.

Currently targeting SWE roles at product-based companies · Available from mid-2026 · Target: 10–16 LPA

The project I'm most proud of. Think Google Docs for code.

• CRDT sync via Y.js — conflict-free real-time editing across multiple users
• Role-based room access — owner, editor, viewer permissions with JWT + refresh-token auth
• Video calls via Stream SDK, AI code assistance, sub-10ms WebSocket sync
• Secure auth — HTTP-only cookies, rate limiting, Zod validation end-to-end
• Stack: Next.js · Y.js · WebSockets · MongoDB · Redis · Stream SDK
• 🔗 Live · GitHub

Not just flashcards — a full learning science engine.

• FSRS algorithm (state-of-the-art spaced repetition, used by Anki) for optimal review scheduling
• Auto-generated flashcards from any topic using Gemini AI + Groq
• Gamification engine — streaks, XP, leaderboards to keep users coming back
• Stack: Next.js · TypeScript · PostgreSQL · Drizzle ORM · Gemini AI · Groq · Upstash Redis
• 🔗 Live

Watch anything in sync, with anyone, no account needed.

• Sub-second video sync across peers using WebRTC mesh networking
• Zero-account onboarding — share a link, watch together instantly
• Real-time chat via Socket.io alongside video playback
• Stack: Node.js · Socket.io · WebRTC · Express · Tailwind CSS
