Built on questions.
Backed by analysis.

Start with financial reporting and business intelligence, then explore the research behind my analytical toolkit.

FEATURED INDUSTRY EXPERIENCE / LARSEN & TOUBRO

Financial reporting.
Rebuilt with SQL & PySpark.

During my data analytics internship, I translated SQL-based financial-reporting logic into PySpark workflows for outstanding-ageing and due-payment analysis, then validated the results against the SQL baseline.

01 / UNDERSTAND

Reporting logic

Work through stored-procedure rules and the financial records they describe.

02 / TRANSFORM

PySpark workflows

Use DataFrames, joins, aggregations and window functions to reproduce the logic.

03 / CHECK

SQL validation

Compare outputs against SQL results to validate reporting consistency.

04 / INTERPRET

Payment visibility

Identify overdue and unbooked payment records for outstanding-ageing analysis.

Try a payments-ageing demo.

An independent, interactive illustration with fictional GBP and INR records, a downloadable dataset and reproducible SQL. It is not employer data, source code or a claim of production results.
