About me
Hi, I'm Sahil. Since August 2025, I've been transforming messy data into clean, actionable insights. I specialize in processing large datasets (20k to 400k+ rows, 10+ columns) using Python, Pandas, and NumPy. I clean data with zero loss, appending updates side-by-side without altering raw columns. With every project, you get: A detailed .txt log report documenting every error fixed. A custom interactive HTML dashboard (HTML/CSS/JS) for seamless visual analysis. Tools: Python, Pandas, NumPy, Jupyter Notebook, HTML, CSS, JavaScript.... Read more

Freelance Data Analyst And Automation Developer

Self Employed • Self-employed

Aug 2025 - Present • 1 yr

As an independent freelance developer, I have successfully delivered 10+ end-to-end data cleaning and visualization projects. I specialized in handling large, complex datasets ranging from 20,000 to 400,000 rows with up to 20 columns of raw data. Using Python, Pandas, and Jupyter Notebooks, I built custom automation pipelines to perform deep data cleaning, handling missing values, duplicates, and data types without ever altering the client's original raw data. Instead, I carefully appended new, cleaned columns side-by-side for 100% data integrity and easy comparison. For every project, I delivered two key components: a highly detailed text (.txt) log report documenting every single error fixed for technical auditing, and a custom interactive HTML/CSS/JavaScript dashboard featuring advanced, easy-to-read visual charts and KPI cards for seamless business analysis.
