IT graduate from Delhi Technological University (2025) · Backend-leaning full-stack engineer
I build production-deployed apps that solve real engineering problems.

A production-deployed AI writing app built on real distributed-systems decisions, not glue code.

Stack: React 19 · Node.js · Express 5 · MongoDB Atlas · Redis · BullMQ · Gemini 2.5 Flash · Vercel + Render

• Chunk-based document storage — only modified sections are persisted on autosave, replacing naive full-document writes
• Per-chunk version conflict detection with UI resolution modal for concurrent edits
• Streaming AI (8 actions) over Server-Sent Events with Redis locks preventing duplicate calls
• Background export workers (BullMQ) for non-blocking PDF/DOCX generation with retries
• Multi-tier rate limiting + daily AI quotas with graceful degradation when Redis is unavailable
• Dual-path JWT auth — debugged & fixed iOS Safari ITP cross-site cookie failure on cross-origin deployment
