About Me

Passionate Engineer.
Relentless Problem Solver.

I'm a B.Tech Information Technology student at JSS Academy of Technical Education, Noida (CGPA: 7.9), with hands-on experience building scalable backend systems, distributed infrastructure, and AI-powered services.

Currently interning at CloudCrane as an SDE Intern, I architect backend services with PostgreSQL, Supabase, and real-time APIs, build CI/CD pipelines with GitHub Actions, and shipped an end-to-end AI pipeline (STT → LLM → TTS) with real-time audio streaming.

I'm passionate about system design, distributed computing, and algorithm optimization — and I'm a LeetCode Knight (Top 3.63%) with 1500+ problems solved across LeetCode, Codeforces, and CodeChef.

Where I've Worked

CloudCrane

Software Development Engineer Intern

Nov 2025 – Present Remote, India
  • Shipped Gobbles — a production Voice AI waiter with a complete mic → STT → LLM → TTS pipeline: built Express voice APIs, integrated OpenAI transcription with menu-aware prompt orchestration, ElevenLabs TTS with key caching, ffmpeg multi-format audio normalisation, and per-IP rate limiting.
  • Engineered a custom AudioWorklet with a self-growing RingBuffer (24kHz, 30s capacity) for glitch-free PCM16 streaming playback off the main browser thread — plus a base64 PCM16-to-Float32 decoder and React useSpeech hook with full recording lifecycle and state machine UI (idle → listening → processing → speaking).
  • Accelerated feature delivery by building scalable RESTful APIs in Node.js/TypeScript with JWT + Google OAuth and React frontend components, shipping 5+ production features end-to-end across Agile sprints.
  • Improved deployment reliability by maintaining CI/CD pipelines via GitHub Actions with PR-based code reviews in a fast-paced startup environment.

Things I've Built

Sage

LLM Agent & RAG Pipeline

Oct 2025

  • Built a production-grade LLM agent microservice using FastAPI — document ingestion, semantic retrieval, and multi-turn response generation with streaming output.
  • Improved retrieval accuracy to 93% and cut latency by 60% using hybrid retrieval: BM25 + FAISS vector similarity with Reciprocal Rank Fusion and cross-encoder re-ranking.
  • Exposed clean REST endpoints for ingestion, retrieval, and generation with structured JSON logging and security-aware API design.

Quill

Real-Time AI Collaborative Editor

Nov 2025

  • Enabled conflict-free real-time collaboration for 10+ concurrent users at sub-200ms latency using WebSocket sync and Yjs CRDT.
  • Integrated Google Gemini API for AI text enhancement via SSE streaming; implemented JWT auth and role-based access control.
  • Reduced bandwidth by 60% using CRDT delta propagation — from 12 KB to under 5 KB per edit.

Snip

Distributed URL Shortener

Mar 2026

  • Achieved sub-millisecond p99 latency and 95% cache hit rate using Redis cache-aside architecture with async SQLAlchemy under sustained load.
  • Implemented token-bucket rate limiting, Base62 slug generation with collision detection across a 3.5T+ keyspace, TTL-based expiry, and atomic click analytics.
  • Containerised with Docker Compose; deployed serverless on Vercel with Supabase PostgreSQL and Upstash Redis.

SubDub

Subscription Tracker SaaS

2025

  • Built a full-stack subscription management SaaS with JWT auth, subscription CRUD, and a React 19 + Vite 7 frontend deployed on Vercel.
  • Architected durable email reminder workflows using Upstash QStash — 4 reminder variants with automatic retries and scheduled delays.
  • Secured API with Arcjet rate limiting & bot detection; Nodemailer SMTP with templated reminder emails per renewal cycle.
