Hi there! 👋
I'm Tusar Goswami.
I’m a Computer Science undergraduate at Lovely Professional University specializing in AI-driven solutions and full-stack development. I enjoy building things that actually work, focusing on Agentic Workflows (LangGraph/LangChain) and scalable web platforms.
Architecting agentic pipelines and real-time systems that hold up under load.
ABOUT
I'm a Computer Science undergrad at Lovely Professional University, originally from Kolkata. I build systems end-to-end — schema design up through the agent orchestration layer sitting on top of it.
Most of my recent work lives in multi-agent AI. The Deal Desk is a 7-node LangGraph pipeline where agents debate an investment thesis in parallel and converge on a deterministic score — no black-box verdicts. Head-2-Code is a real-time competitive coding platform running live code execution for 50+ concurrent users at sub-300ms latency. Jarvis is a voice-driven assistant that turns natural language into browser and system-level actions.
Core stack: React, Node.js, PostgreSQL, Python — plus LangGraph, LangChain, and the Gemini API for anything agentic. I contribute to UltimateHealth, an open-source healthcare platform, through GSSoC 2026.
Outside of building: competitive programming. Global Rank 746 of 34,000+ in LeetCode Biweekly 176, 5★ Java/C++ on HackerRank, 500+ problems solved, and a finals run at Fynd Hacktimus 2025 among 1,000+ participants.

PROJECTS
01 · Architect
The Deal Desk
Designed a 7-node LangGraph pipeline where parallel fan-out debate agents argue an investment
thesis, route into conditional rebuttals, then converge through a deterministic 5-dimension
scoring model — removing the variance you get when an LLM grades its own reasoning.
Grounded every recommendation in the Tavily API, so agents argue against live market data
instead of stale training knowledge. Built a 3-model Gemini fallback chain with automatic
quota-pool switching, Zod schema validation, and retry logic, holding pipeline failure rate
near-zero even on free-tier quotas. Shipped the frontend on an async 2-phase API — POST 202 into
an SSE stream — so users watch agents reason in real time, backed by fire-and-forget Postgres
persistence and input sanitization.
Tech: JavaScript, LangGraph, LangChain, Tavily API, Node.js, Express.js, React.js, PostgreSQL, SSE
02 · Creator
Head-2-Code
Built a gamified coding platform — friend challenges, custom contests, daily problems — serving
50+ concurrent users at sub-300ms end-to-end latency over Socket.IO.
Wired Judge0 and Monaco Editor for live execution across 10+ languages at a ~250ms average
verdict time, then layered a Gemini-powered debugging assistant on top for complexity analysis
and code review, running on a horizontally scalable Node.js/MongoDB backend on AWS EC2.
Tech: React.js, Node.js, Express.js, MongoDB, Judge0 API, Socket.IO, Monaco Editor, AWS EC2, Gemini API
03 · Creator
Jarvis
Built a modular, voice-driven assistant — hotword detection, Selenium-based browser automation,
system-level task execution — that cut manual workflow time by ~40%.
The NLP command-interpretation layer runs on Gemini API, translating natural language into
executable actions. A multi-threaded architecture holds sub-second response latency even across
concurrent interaction threads.
Tech: Python, Gemini API, Selenium, NLP, Multithreading

3D Space PortfolioAn interactive 3D portfolio built as a navigable solar system instead of a scroll page. Each planet maps to a section — projects, skills, certificates — explored via rocket or astronaut, with animations and layout tuned for desktop and mobile alike.
Tech: React.js, TypeScript, Three.js
