Who I Am

Hey! I'm Navin Ravichandran, an aspiring Data Analyst with a background in Construction Project Management. I discovered my passion for data analytics and made a deliberate pivot toward a career in data science and BI.

I believe in learning by doing — every project I build solves a real problem, from analysing Walmart's sales patterns to building a local gym discovery platform for the Indian market.

My goal is to join a data team where I can apply analytical thinking, drive business decisions with data, and keep growing every single day.
