Raw data in. Sharp questions. Decisions out.
I'm Rajay Ajay Jain — Data Analyst. I build the pipeline, write the query, and shape the story. The work isn't done until someone makes a better call because of it.

The person behind the pipeline.
I'm an entry-level Data Analyst based in Goa, India who believes the hardest part of analytics isn't the query — it's making sure the right person trusts the answer enough to act on it. I spend my time in that gap: cleaning inconsistent data, modelling it so it holds up under scrutiny, and shaping the output into something a non-technical stakeholder can read in under a minute.
My toolkit runs from SQL and Python for the heavy lifting, through Power BI or Tableau for the story, and into ETL pipelines and star-schema models that keep the analysis reproducible. I care about data storytelling as much as data engineering — a dashboard nobody opens is a failed project, no matter how clean the schema underneath it is.
Query results: capabilities.
Core languages run deep; the tooling around them runs wide.

TOOLS & LIBRARIES
MODELING & PRACTICES
Real projects, real metrics.
Selected projects from github.com/RajayJain, with headline numbers pulled straight from each README.
Learning, pipelined.
Each stage extracts a new skill, transforms it into practice, and loads it into real work.
SQL & Excel as first languages
Started with spreadsheets and relational queries — learning to ask questions data could actually answer, and to distrust numbers without a clear source.
Python for real analysis
Moved into Pandas, NumPy and Matplotlib/Seaborn to clean messier datasets, automate repetitive reporting, and explore data before committing to a conclusion.
Power BI & dashboarding
Learned that a chart is a claim — built dashboards designed to be read correctly in ten seconds by someone who has never seen the underlying table.
ETL, modeling & validation
Building Python/SQL ETL pipelines, star-schema models and validation checks — the layer that keeps analysis reproducible, not just correct once.
Verified credentials.
Rigorous coursework, end-to-end processing, and continuous upskilling.
