Shinobi Saga is a 2D Anime-Inspired Fighting Game developed using Python and Pygame. The project recreates an intense battle between Naruto and Sasuke with Smooth character animations, combat mechanics, projectile attacks, health systems, and interactive game screens. The game was built completely from scratch using object-oriented programming principles and modular architecture, providing an engaging desktop gaming experience while demonstrating strong game development fundamentals.
An End-to-End production-grade analytics project analysing 600,000+ food delivery orders across 10 Indian cities (2022–2025) using Python, PostgreSQL, and Power BI. Covers the complete pipeline — synthetic data generation, star schema design, ETL loading, advanced Python EDA, and a 7-page interactive Power BI dashboard — solving 7 real business challenges including customer retention, revenue optimisation, restaurant performance, and market expansion strategy.
This project builds a production-grade Data Warehouse for Samsung — from scratch — using the Medallion Architecture (Bronze → Silver → Gold). The pipeline begins with Synthetic Data Generation simulating Samsung India's real business operations across Sales, Finance, Customer Relations, After-Sales Service, Supply Chain, and Marketing, then processes that data through three structured warehouse layers into analytics-ready Gold views.
A comprehensive End-to-End SQL Data Warehouse project built in PostgreSQL, implementing a full Bronze → Silver → Gold layer architecture. Integrates ERP and CRM source data, builds a Star Schema with clean dimension and fact tables, develops ETL pipelines, and applies 12 modules of Advanced SQL Analytics — covering customer segmentation, product performance, cohort analysis, and cumulative reporting.
Designed and Developed a fully Responsive Personal Portfolio Website from scratch using pure HTML, CSS, and JavaScript — with zero frameworks or libraries. The site serves as a central hub to showcase my Skills, Real-World Projects, Internship Experience, and Personal Artwork to Recruiters and the Tech Community. Deployed live on GitHub Pages with automatic updates on every push to main.
A Bluetooth-controlled 4WD Robotic Arm Vehicle built using Arduino Uno, featuring a 4-DOF Robotic Arm, Voice Command Support, and a Custom Android Application developed with MIT App Inventor. The robot combines a powerful 4-wheel-drive rover base with a servo-controlled robotic arm, allowing users to remotely navigate the vehicle and manipulate objects wirelessly.
A fully Interactive Excel dashboard analysing Blinkit's grocery sales performance using KPIs, pivot charts, and dynamic slicers.
