Cover image for In this project, I worked
In this project, I worked on cleaning raw sales data and transforming it into meaningful insights using Microsoft Excel. I applied pivot tables and interactive filters to organize information by city, product, payment method, and customer. The analysis highlighted key performance metrics such as total quantity sold, total revenue, and profit across five major cities. Mumbai emerged as the top-performing city with the highest revenue and profit, while Chennai showed the lowest figures. The final dashboard included a 3D bar chart for clear visualization, making it easy to compare city-wise performance at a glance. This project demonstrates my ability to: Perform data cleaning and structuring Build pivot tables for multi-dimensional analysis Apply filters for dynamic exploration Create professional charts for business insights Impact: The analysis provided actionable insights into regional sales performance, helping identify strong markets and areas for improvement.

Cover image for Excited to share my latest
Excited to share my latest project — a modern gym & yoga studio demo website built with Next.js, React, and clean custom styling. This project focuses on a premium fitness brand aesthetic with a responsive layout, engaging hero section, class highlights, trainer profiles, membership plans, facilities, and a strong contact/WhatsApp CTA. I also structured the content in a single data file so the site is easy to customize for any gym, yoga studio, or wellness brand without changing the core design. It’s a great example of building a high-converting, mobile-friendly landing page with a clean user experience and scalable content structure. #NextJS #React #WebDevelopment #FrontendDeveloper #GymWebsite #YogaWebsite #FitnessBrand #WellnessBrand #LandingPage #ResponsiveDesign #WebsiteDesign #ModernWebDesign #PortfolioProject #WebDesigner #SmallBusinessWebsite #FreelanceWebDeveloper #UXDesign #BrandWebsite #CreativeDeveloper #Contra #ContraProfile - If you want, I can also make this: - more premium/professional - more concise and punchy - tailored to a specific niche like fitness, yoga, salon, cafe, or real estate.
