A little bit about me.

I'm a Data Analyst who's spent the last few years living inside the whole analytics pipeline — from Python ETL and PostgreSQL modelling to shipping the Power BI dashboards leadership actually opens.

Most recently I was AI & Data Intern at YCX, where I rewrote a 4-hour multi-source pipeline into a Python + n8n workflow that runs in under 10 minutes and cut reporting errors by 25%. I'm just as comfortable writing window functions in SQL as I am building a DAX measure, tuning a Tableau parameter, or running a VADER sentiment model over unstructured text.

Currently based in London — MSc AI (Merit) at Queen Mary, BSc CS from SIES Mumbai — and looking for my next Data Analyst role.
