My projects
This page showcases all the independent projects that I have completed recently and during my time at General Assembly during Data Analyses Immersive boot camp. These projects have helped me grow as a data analyst and provided the technical skills required in a fast-moving business environment.
01
A Dynamic Dashboard for Volunteering Organization
I recently collaborated with Creative Reaction Lab (CRXLAB) on data. analysis project. CRXLAB educates, trains, and challenges black and latinx youth to become leaders in designing healthy and racially equitable communities. Keep up the good work, Creative Reaction Lab (CRXLAB).
For CRXLAB, I performed end-to-end data management, meticulously refining and organizing data to enhance quality and accessibility. I also designed a dynamic Google Sheets dashboard that offers easy access to essential key performance indicators (KPIs), enabling swift, well-informed managerial decisions.
Moreover, I streamlined data collection by implementing a Google Forms system, ensuring seamless data updates and convenient dashboard maintenance.
This setup will eliminate the future need to hire a data analyst to clean the data and update the dashboard. By the estimation of the client, this project saved them over 6000$.
The logo and data used in this dashboard are fake in order to ensure data privacy and security.

Decoding the Twitter Pulse: Unveiling the Sentiments Shaping US Political Discourse
In this project, I have used the Global Political Twitter dataset obtained from Kaggle and the Twitter API for my project to conduct political sentiment analysis using the roBERTa model by Huggingface. Over 72,000 tweets that originated from the U.S. were extracted using intricate string manipulation. Please click here to learn more about the data cleaning process.

Navigating A Pandemic
This dashboard visualizes the monthly progression of COVID-19, including total case numbers, death counts, and the countries with the highest and lowest fatalities. It also explores the positive correlation between a country's average GDP, average diabetic prevalence, and the prevalence of COVID-19 cases.

Forcasting US wind capacity
The term wind capacity refers to the number of wind turbines in the U.S. Since 1982 the cumulative number of wind turbines has grown significantly. In the project, I used the Arima model to predict wind turbine numbers in 2025.
06
Personal Finance Dashboard
This finance dashboard is a personal project and an effort to manage my own expenses, but the dataset used for this project was randomly generated. I have used multiple pivot tables, lookup functions, vstack, table calculations, and a slicer to create this dynamic dashboard in Excel. You can click the button below to download the Excel file.
