About Me

Sadhana Rani Sankar Narayan
Data Analyst & Application developer

I'm a perpetually curious developer who loves working with data to extract meaningful patterns and valuable information about the world around us. I am experienced working with large datasets using Python analytic libraries (Pandas, NumPy, SciPy, and more) and SQL uncovering patterns and actionable insights and publish the findings through APIs (Flask).
I work with Plotly.js, D3, Matplotlib(Python) to bring life to my findings with highly descriptive visualizations. In the long run, I see myself driving business decisions of a successful organization that brings positive impacts to society. I also believe every step of the way is as important as the destination.

Portfolio

Below are some of my projects to showcase my skills in Python, Pandas, Matplotlib, Numpy, Seaborn, Javascript, D3, Plotly, Leaflet etc. in application development and data analysis.

Severe Weather Dashboard

Exploratory data analysis and visualization, full stack development project. Data analysis of hailstorms, tornados, and severe wind events that occurred in the USA from 2010-2016 using Python, Pandas, Plotly, Leaflet and D3.js.

Tweet Street

Exploratory data analysis project to study Social media (Twitter) sentiments and Stock market information. Data analysis and visualization is acheived using Python libraries namely Pandas, Matplotlib, Tweepy, SentimentAnalyzer.

Approaching Equator

Data's true power lies in its ability to answer questions definitively. Attempting to answer a fundamental question: "What's the weather like as we approach the equator?" Now, we all might think, "Duh. It gets hotter..."
But Proving it is the fun part!

Recent Earthquakes

A Leaflet js based visualization that shows all earthquakes from the past week along with the tectonic plates.

Biodiversity Dashboard

An interactive dashboard implementation of the famous belly button bio diversity dataset using Python, Flask, SQLite, Plotly and D3.js.

Twitter Sentiment Bot
