About Me

Second-year B.E. Computer Science student at St. Joseph's College of Engineering, with a focus on full stack development, data structures, and applied AI systems. Interested in building practical software that solves real problems - from intelligent multi-agent systems to in-store navigation engines.

Full Stack Engineering: Built end-to-end platforms using Node.js, FastAPI, React 18, PostgreSQL, and Tailwind - with JWT role-based authentication and clean, responsive interfaces.
Applied AI Systems: Designed MATSYA AI, a rule-based orchestrator for marine intelligence routing to specialized spatial-risk and language-detection agents, with Gemini-powered synthesis.
Algorithms & Competitive Programming: ICPC AlgoQueen 2026 Finalist. Active in competitive programming with a focus in DSA.
Cloud & Open Source: Oracle Cloud Infrastructure Certified, Microsoft Azure Fundamentals certified, GSSoC and OSCI 2026 Contributor.

Projects

MATSYA AI — Marine Analysis for Tracking, Safety & Yield Assistance

Rule-based multi-agent orchestration system for marine intelligence

Designed a rule-based orchestrator for intent, language, and location detection, routing queries to specialized marine-intelligence and spatial-risk agents.
Built the final synthesis agent that merges all agent outputs into structured text/speech responses — optionally using Gemini for natural language wording.
Kept data retrieval entirely LLM-free for reliability, with per-response trace, evidence provenance, and confidence scoring.
Stack: Python, Gemini API, Multi-Agent Architecture

CartZen — Retail Management Platform

Full-stack in-store navigation and hypermarket operations platform

Built a platform that generates optimized in-store walking routes using store layouts modelled as weighted graphs — Dijkstra shortest-path + TSP optimization with accessibility constraints and live rerouting.
FastAPI + PostgreSQL backend, React 18 + Tailwind frontend, JWT role-based auth.
Integrated Gemini API for an AI shopping planner, an offers engine, sales analytics, and budget-tracked lists.
Stack: FastAPI, PostgreSQL, React 18, Tailwind, JWT, Gemini API

Personal Blog Website

Full-stack blogging platform with auth and post management

Users can register, log in, and create, edit, and manage blog posts with session-based authentication and password hashing.
Stack: Node.js, Express.js, EJS, PostgreSQL

Drum Kit

Interactive browser-based drum machine

Plays drum sounds via mouse clicks or keyboard key presses using JavaScript event listeners with real-time audio playback and visual button feedback.
Stack: HTML, CSS, JavaScript
