I'm a 2nd-year CSE student focused on full-stack web development and system architecture. I build resilient, privacy-first applications and spend the rest of my time practicing Data Structures and Algorithms.

• Languages: C++, Java, JavaScript (ES6+)
• Frontend: React.js, HTML/CSS
• Backend: Node.js, Express.js
• Database & Tools: MongoDB, Git, GitHub, REST APIs

Epiqora | Node.js, Express, JavaScript, Gemini AI

A privacy-first, stateless AI skincare assistant. Instead of a basic API wrapper, I engineered a closed-loop system featuring transient state management, strategic multi-model LLM routing for token optimization, and custom jittered exponential backoff to handle third-party API traffic spikes. Zero user data is retained in the database.

LabourGuard | MongoDB, Express, HTML/CSS, Node.js

A comprehensive labor law compliance system. Built a robust backend architecture featuring a core compliance engine that actively tracks working hours, detects legal violations, and visualizes data through an intuitive employer dashboard.

I maintain structured, daily problem-solving repositories to keep my core fundamentals sharp:

• C++ DSA Practice: One file per problem, organized by lecture and concept.
• Java Mastery Journey: Structured practice for core OOP concepts and algorithmic problem-solving.
