About

Finance mind.
Data instinct.

I'm a Chartered Accountant from ICAI who spent seven years auditing some of India's most complex organisations across banking, infrastructure, and power. That work gave me something rare: an instinctive feel for where financial data lies, misleads, or reveals truth under pressure.

Now I'm combining that domain depth with serious analytical capability — Python, SQL, Power BI, Tableau, financial modelling, and data warehousing. My GitHub portfolio includes projects from NHS capacity analysis to DCF valuation of DMart to a full data warehouse build in SQL.

I'm not a generalist analyst who learned some finance. I'm a finance professional who has earned the analytical tools — with a particular focus on risk analytics, fraud detection, and financial intelligence.
