About

Crafting software that quietly does the heavy lifting.

I'm Gaurav Kumar — a full-stack developer at B3 Solution shipping React + Node products that real finance teams use every day.

I built the company's flagship Amazon Analytics platform — six modules tracking ACOS, ROAS, CPC and ad spend — alongside four finance dashboards that cut reporting time by 70% and automated 60%+ of manual workflows.

End-to-end ownership from architecture to deployment. Quiet code, fast UI, business outcomes.
