About

Building at the intersection of software and intelligence.

I'm a software and AI developer focused on building full-stack applications and intelligent systems. My work spans end-to-end product development, from crafting intuitive user experiences and scalable systems to building autonomous agents, and AI-driven products.

Currently pursuing B.Tech at NIT Jalandhar, spending my time shipping products, experimenting with LLMs, and figuring out how to make systems smarter. When I'm not writing code, I'm probably exploring new tools, reading about system design, or tinkering with something that probably doesn't need to be AI-powered, but is anyway.

Belief> “Sometimes you win, sometimes you learn.”

Selected Work

A mix of AI experiments and full-stack applications.

PartyHost

Voice-first multiplayer trivia, hosted by an AI avatar

A multiplayer trivia game you play by speaking. An AI avatar runs the show, talking and lip-syncing in real time, while on-device vision works out which player just answered.

Jun 2025 — Jan 2026

AI Developer Intern

Maitreyalabs

  • Explored and prototyped several real-time, voice-driven AI systems, from conversational avatars to multiplayer interactive experiences.
  • Built FastAPI backend services that unified speech-to-text, an LLM, and text-to-speech into a single inference pipeline for low-latency, speech-driven responses.
  • Unified multiple inference components into a single concurrent request pipeline, wiring speech-to-text, an LLM, and text-to-speech into a live conversation loop.
  • Shipped cross-platform clients, including a Kotlin Android app over async REST APIs, and applied on-device computer vision for real-time face and speaker detection.
