I make messy data tell the truth.
Data analyst with 2+ years across ETL testing, business intelligence, and analytics — turning inconsistent, real-world datasets into dashboards and decisions people can actually trust.

Two projects that show the same thing from different angles: taking data nobody fully trusted yet, and building the process — not just the chart — that makes it trustworthy.
Disaster relief analytics platform
An end-to-end Power BI platform built for Samarthya NGO to track relief distribution and vulnerability across 3,000 beneficiaries — from inconsistent field records to a star-schema model that leadership and donors could rely on.

Star schema
Fact/dimension model
- Reviewed and reconciled raw beneficiary records for duplicates, formatting issues, and structural inconsistencies before any reporting began.
- Unpivoted wide-format vulnerability data in Power Query into a structure that supports real per-condition analysis.
- Validated geospatial coordinates against beneficiary, habitation, and government master records for accurate mapping.
- Migrated the reporting layer from Looker to Power BI to support interactive geospatial drill-through and custom tooltips.
- Built a Python pipeline against the KoboToolbox API and Google Drive to organize field-evidence photos for verification.
- Implemented object-level security in Tabular Editor so volunteers, admins, and donors each see only what they should.

"Working with Darshana on our Flood Relief 2026 project was exceptional. She built an advanced Power BI dashboard with GPS, photo, and signature validations to ensure transparency. Patient, friendly, and highly skilled — she delivered a clean, user-friendly tool while upholding beneficiary dignity."

- Cleaned and standardized views, likes, comments, and subscriber counts for reliable comparison across channels.
- Designed engagement-score and growth-score gauges that benchmark each filtered slice against the overall average.
- Built continent- and country-level breakdowns plus top-10 rankings for the most engaging channels and videos.

Open to meaningful work, not just job titles.
I'm open to different ways of contributing — from freelance dashboard work to collaborations, volunteering, and practical projects with students or early-career teams.
A small mission I'm building
Good analytics shouldn't be out of reach for smaller organizations.
I'm currently looking to take on selected free or low-cost dashboard projects for small businesses, NGOs, community initiatives, and organizations where better reporting can create real value. Pricing can be flexible — based on the organization's situation and ability to pay.
Let's use data to make a practical impact.Freelance Projects
Power BI dashboards, data cleaning, reporting, SQL analysis, KPI development, and business intelligence for real-world business needs.
Project Collaboration
Collaborate with analysts, developers, founders, researchers, or teams building practical data products and analytics projects.
Volunteer / Pro Bono
Open to meaningful analytics work for NGOs, social-impact organizations, community initiatives, and causes where data can help.
Student & Early-Career Projects
Happy to collaborate on portfolio projects, dashboards, data analysis initiatives, and practical learning projects.
Bring me a dataset nobody trusts yet.
I'm open to data analyst and BI roles — remote or Coimbatore-based. Reach out directly, or connect on LinkedIn or GitHub.
Location
Coimbatore, Tamil Nadu
